How to choose an oil filter

The choice of oil filter, despite the overall simplicity of the design, includes a lot of features and subtleties that must be taken into account. Expertology magazine recommends special attention For the following aspects:

Filter type.There are three types oil filters:

1. four-way - have an overproof valve in their composition, which regulates oil pressure in the lubricant system. It protects seals and gaskets between blocks from damage and breaks, the bypass excess pressure from the engine crankcase. In the case of full operation of the filter resource (its clogging), in order to avoid oil starvation, the valve provides the flow of polluted oil, in order not to bring the engine to the overheating state.
2. partial-statement - provide more subtle filtration than total-current models, in connection with which it requires more time to flow the cleaning process. However, such a principle of operation avoids pressure drops in the event of a filter clogging, as well as with random sticking of the bypass valve.
3. combined - Filters Extractic oil purification, combining the advantages of the first two types and eliminate their characteristic disadvantages. It is more expensive than the rest, but allow you to largely increase the resource of the work of rubbing steam and are recommended for use in heavy-loading engines.

Control of the bypass valve. This aspect is quite difficult to check when purchasing a filter, however, if such an opportunity is provided, be sure to make sure that the opening pressure of the valve was slightly higher (literally by 0.1 bar) of the upper limit of the relevant pressure of the system. In this case, you accurately secure the engine from the ingress of unfiltered oil with a high content of abrasive particles. Similarly, you can organize checking the reverse shutdown valve to the closing density, in order to exclude the oil leak while the engine idle.

Filter paper thickness. This parameter directly affects the values \u200b\u200bof the filter working resource. Subsolation and complete workout is the higher, the greater the thickness of the paper layer. In addition, you should consider the moments associated with the maximum temperature of the oil heating in the engine. Be sure to find out what the permissible temperature of the oil filter is valid, in order not to provoke the burnout of the paper when the engine is normal.

Housing integrity. The indicator of the secondary importance that can largely influence the operation of the filter. Before purchasing, be sure to make sure there are no external damage to the body, valves, as well as in the integrity of the filter paper.

Manufacturer. In this case, the value of the corporate product is obvious, since falsification is often subjected to rapid failure, and may also entail a number of more critical faults. In this regard, we strongly recommend that you contact the acquisition of products from eminent brands that have certificates of compliance with modern quality standards.

Best Cheap Oil Filters

Goodwill is the rare type of manufacturers, the range of which contains filters of budget, medium and premium price segments. Product quality in all variations is excellent, and the resource strongly depends on those driving modes that the user chooses, the maintenance frequency of the car and its technical condition.

According to experts, the operational conditions of GOODWILL oil filters can be quite enough for 15-20 thousand mileage kilometers, perhaps even with the presence of a residual resource. As for consumers, they, in general, respond about the product complementary, noting his great choice in the retail market. Those who order filters through service centers located on the territory of the country complain about the non-painting of service and incompetence by personnel, but currently these problems are practically leveled.

Dignity

• wide prevalence in the retail market;
• high quality filtration;
• the resource has been laid enough for 15-20 thousand kilometers of run;
• high dependence of filters from operation.

disadvantages

• not found.

The market phenomenon is far from new and until recently very situationally, Sakura is the result of qualitatively done work on making filters of the required qualities with minimal costs for their subsequent acquisition. Obedience to Japanese style trends, the entire product produced passes strict control on the most important operations, excluding secondary steps from manufacturing technology.

The results of such manipulations are more than impressive: the percentage of marriage barely reaches 4%, and the approximate working resource varies within 10 thousand kilometers. A number of independent tests still revealed some shortcomings related to the work in the hard work of overheating, but in essence it is impossible to attribute such behavior. User reviews, in turn, confirm the good quality of products at nominal modes of work, referring to the stable and easy operation of the engine during operation. Reinforces good renome and very low price, almost the same as in the case of filters domestic production.

Dignity

• very low cost of products;
• the working resource of one filter is enough for 10 thousand kilometers of run;
• low level marriage associated with rigid control of production;
• wide prevalence in the cities of Russia;
• acceptable filtering quality.

disadvantages

Magnitogorsk manufacturer of budget oil filters, regenerated after a complete stop of production due to lack of financing and low demand in manufactured products. The production production "Belmag" was launched in 1996, when the "Maswings" were used to the conveyor of the domestic car industry. Once upon a great dependence on the only (in fact) of the customer, the company was not able to survive a decline in the automaker niche and the arrival of new companies to the market, declaring his own closure.

The new milestone in the history of "Belmag" was laid with the arrival of the United Renault-Nissan concern, which concluded the next contract for the delivery of oil filters for domestic conveyors. Initially mediocre, the quality of products with capacity building began to grow gradually, and to date, it has reached the ceiling within the budget segment, equal to the recognized grants.

Dignity

• in stock Oil filters for cars VAZ, Renault and "Nissan";
• high quality within the segment;
• low price due to selection of inexpensive materials;
• wide prevalence in retail.

disadvantages

• not detected.

Russian manufacturer who fell into the rating of the best thanks to the production of oil filters not only for passenger cars, and for cargo machinery, providing products with the whole territory of the CIS. The latter became possible solely due to the fact that at the stage of the formation of the company was able to provide a satisfactory quality of filter elements. Later, his own developments were reinforced by foreign technologies, in order to provide "masselkers" even greater level of compliance with the adopted quality standards.

Despite the low cost of filters from the "Auto unit", it is often impossible to find them in retail. The fact is that the work of the company rests on the need to work on orders, delivering a product with straight to conveyor lines of the VAZ, KAMAZ factories, the Urals, etc. In this regard, only a small part of the consumables produced (no more than 10-15%) goes to retail SALE, which is the most negative quality of the brand from the position of consumers.

Dignity

• work on the equipment of conveyors automotive factories domestic and overseas markets;
• nominally high quality products, compliance with international quality and safety standards;
• low price.

disadvantages

• only a small part of oil filters enters retail sale.

Without exaggeration, the leading manufacturer of filters for cars engaged in the development of inexpensive products for the domestic and foreign market of spare parts. The main advantage and feature of this brand is the existence of a contract for the supply of consumables to Volkswagen plants located in Russia.

According to experts, the value of Big Filter is in a wide range of oil filters manufactured: the lineup There are more than 100 types of product that has passed a multi-step test for compliance with quality standards. In particular, special attention is focused on providing good job Shut-off valves that prevent flowing oil during engine idle. As for consumers, many prefer to put filters from "Big" in return to the staff at the stage of the work of the working resource, and, in general, they are satisfied with the quality of the engine work. It is noteworthy that the firm always seeks to update product range, and recently produces an increasing amount of technological products.

Dignity

• development of filtering elements for enterprises of domestic and foreign automotive concerns;
• high degree of product recognition (characteristic green color corps);
• proper quality of manufacture;
• an affordable price tag for the entire range.

disadvantages

• not found.

The best manufacturers of oil filters by price-quality ratio

Bosch.

Perhaps the most diligent manufacturer of oil filters of the arrogant price segment, showing excellent results in terms of the quality of the product being produced. In essence, the quality of oil filtering from impurities in Bosch filters can be called the reference on all cut-off of the resource generation: neither bypass valve nor the cartridge have problems with the provision of functions in late operations.

According to experts, the only problem pursuing some of the BOSCH oil filters is caused by the overestimation of the time of normal functioning, which causes a wave of indignation and misunderstanding in the minds of most users. This explains this simple enough: when the corporation's concentration on the release of a wide range of products (from the power tools to other consumables from auto parts), control of storage and transportation processes is given very difficult. Alive this factor can only have a minor cost of the product, which combines car owners to make a purchase.

Dignity

• low cost of almost the entire range of oil filters;
• high quality cleaning oil from impurities;
• abundance of proposals in retail;
• low marriage percentage.

disadvantages

• some filters exhaust the working resource before the term-declared period.

According to the assurances of world experts, Hengst is one of the segment leaders in the number of collaborative relations with the famous automakers. On the establishment of connections and the formation of a brand, what it is now, has left more than 50 years, but the acquired status of that definitely stands. The painstaking work resulted in the signing of contracts for the supply of oil filters to the Ford, Mercedes-Benz conveyors, Isuzu, BMW and many others, after which the firm came to the fame of the most demanded in his niche.

According to users, such a complete element in the oil purification system from impurities has a positive effect on the safety of the engine, creating excellent conditions for its sustainable work during the entire operating time filter. If we talk about the scale of production of Hengst, since all the time it produced about 5 thousand different filter modules, which were invariably became competitive even in comparison with premium models.

Dignity

• a large number of contract delivery contracts directly for the conveyor assembly of the car;
• more than 5 thousand oil filters developed in the entire history of the company's existence;
• high working resource, toughly limited by the manner driving of the car owner;
• adequate prices and the magnificent ratio of their quality.

disadvantages

• not detected.

Fram.

Like Purflux, Fram is a representative of the SOGEFI group of companies, whose name is associated with the concept of "quality" and "durability". Unlike a premium analogue, this brand is focused solely on the production of products in retail sale in the secondary market, pursuing the purpose of equipping with oil filters of cars predominantly used.

The choice of such a specific target audience is not accidental, and the calculation is focused on the consumer's mass. As a result, high sales figures with an average price tag, thousands of satisfied buyers and high places in all sorts of ratings of the best. In addition, the main advantage of the trademark FRAM for experts is seen by the observance of environmental friendliness (it is expressed in the creation of "facilitated" versions of filters) and the focus on the permanent expansion of the range. Considering the scope of activities, this brand clearly could not have passed past the troika of the nominees.

Dignity

• focus on the secondary market as a whole and for used cars in particular;
• the development of "lightweight" versions of filters, characterized by fewer polluting waste while maintaining performance;
• constant expansion of the range;
• the average price level.

disadvantages

• not detected.

Nitto.

The Japanese company for the manufacture of filter elements, founded in 1959 in Ibaraki Prefecture, where the main production complex is located. According to official data from the study conducted in 2017, is the largest player of the segment (according to this indicator exceeds UNION), which accounts for more than 20% of the internal market in Japan.

The main advantage of the NITTO company is concluded in concentration on the observance of the strictest control in all aspects of production: from the selection of raw materials to the steps of packaging filters. Such an approach to the case, together with the compliance with the requirements of international standards ISO 9001 and ISO 14001, approved the introduction of innovations, allowed significantly to raise the level of the working resource (up to 30-40 thousand mileage kilometers under the condition of normal operation of the car), withstanding quite loyal to the consumer Price frames.

Dignity

• high assessments of world expert councils and experienced users;
• work on the introduction of innovations into filter manufacturing technology;
• more than 15 years of work in the domestic Russian market;
• increased workflow of products.

disadvantages

• not found.

Hyundai / Kia.

Non-specialized Korean production oil filters designed to install in the cars of the same stamps. From the start of the manufacture, they used low popularity in consumers, although they were intended to be installed in warranty service centers. The reason for this was an extremely unstable work quality, accompanied by rapidly generating the resource and the need to quickly replace the element to the new one.

Over time, the situation has been established mainly due to the opening of a full-fledged research office for testing existing and prototypes. Korean engineers managed to identify the most weak spots In the design of oil filters, after which the painstaking work began on their elimination of a few years. At the present stage, Hyundai / Kia's branded product is preferred, rather than competitors from Nitto, Sakura or more than a UNION.

Dignity

• high working resource;
• the possibility of ordering through the company's service centers and, as a result, a good service;
• middle rates for the original product.

disadvantages

• the residual presence of some "sores" to be quickly corrected.

SCT.

The German company SCT is positioned by many experts as a complete competitor company MANN, however, with a much less wide scale in terms of financing and production volumes. The main "point" of the sale of oil filters for it is the CIS countries, the main of which, of course, is Russia. The domestic consumer is not like a sign with this product, and responds about it quite well. Yes, in a large assortment there was a place for not very successful representatives, but it is rather an exception to the rules than established regularity.

As in the case of Mahle, the main advantage of the SCT company lies in adequate pricing policy, which supports a thin balance between the cost and operational parameters. According to experienced car owners - this excellent option To buy an average price segment, especially for car old formations.

Dignity

• optimal combination of price and operational parameters;
• wide product prevalence in Russia;
• high quality lubricating liquid filtration;
• low level of marriage and fakes in the secondary market.

disadvantages

• separate filter models have a very low service life.

The best manufacturers of oil filters of a premium segment

Mahle.

Like MANN, Mahle is a representative of the German group of manufacturers engaged in the manufacture of oil filters. That's just unlike a competitor, it pays much more attention. secondary market, Along the way, shipping "Maswings" to the conveyors of at least famous automakers of their country (which is only cooperation with BMW and Mercedes-Benz). Among other things, Mahle is an active developer of expensive consumables for the VAZ brand's cars - on the coincidence of circumstances can be observed in the now removed from the conveyor "Priors".

According to the manufacturers themselves, the resource of one oil filter may be enough for a run of 50 thousand kilometers. Experts, in general, support this statement, but in such a transcendental figure they believe with great difficulty, taking place on a much less embarrassing imagination of 30 thousand mileage. For consumers, the parameters of fine filtering are first place, thanks to which the engine works amazingly "purely". Given all the above, even with a small amendment to the loud words, the investment in the purchase of a product from Mahle will be quite justified.

Dignity

• the declared working resource of oil filters reaches 50 thousand kilometers;
• the presence of strict operational control, as well as careful selection of materials and raw materials for the initial stage of production;
• implemented concept of creating valves from heat-resistant rubber high degree of strength;
• big focus original Product In the secondary market.

disadvantages

• high price.

The trademark of the SOGEFI group of companies, under the logo of which reliable and adequately appreciated filters of cleaning carcase oil from extraneous impurities. Speaking "adequately appreciated", we mean the legitimacy of the established value of working qualities, whose violation is sometimes "sins" no less famous competitors.

According to the established tradition of representatives of the premium segment, SOGEFI (read, Purflux) conducts a comprehensive policy providing consumers to the highest quality product, which is expressed in the creation of a whole research complex (although not the scope that the Union). According to consumers, a thorough comparison of the operating parameters of these oil filters with others often reveals a small Purflux winnings in a value or rational constructive attitude, which is a big plus in the brand piggy bank. In parallel with this, experts allocate the original form of filter paper (it is built in the Christmas tree), which does not make any sense with the exception of difficulties in the forgiveness. For a series of small subtleties and a very competent price policy, this trademark deserves the second line of the rating.

Dignity

• loyal to consumers price policy;
• high quality filter elements;
• "Tricks" forms of individual components of the cartridge that make falsification;
• the presence of a research center.

disadvantages

• not found.

Mann.

MANN is a product of the fusion of the two oldest German auto parts manufacturers (Filterwerk Mann and Hummel GmbH), which rushed to the scale of the main current corporation of the whole of Europe. It is famous for a very rigid approach to controlling the quality of its products, which is a positive effect on the percentage of marriage (less than 2% of the total). The production control here begins straight from the stage of preparation of raw materials, which makes it possible to eliminate even the slightest deviations from the nominal introductory as the product is promoted.

According to users, the quality of oil filters from MANN is manifested not only by the degree of filtering, but also a notorious increase in the life. As for experts, they note an extremely risky, but very effective method of supplying a freshly developed product with straight to conveyor lines of famous automakers, including the entire VAG group, as well as a number of brands known in Russia ("Nissan", "Peugeot" and etc.) It is also worth noting the focus of the manufacturer on the production of products for the retail market in quantities sufficient to meet the needs of car owners.

Dignity

• the largest representative of European oil filter manufacturers, which is a title supplier of a large number of world automakers;
• attention is paid to the production of filter elements for domestic cars;
• the desire to control the quality at all stages of product development.

disadvantages

• the presence of a large amount of falsification in retail.

Union

An eminent manufacturer of premium oil filters from Asia, who fell into the rating thanks to a magnificent reputation among the consumer segment. He has general agreements with the overwhelming majority of automakers in Japan, Korea and China on the supply of conveyors with oil filters: they can be found in the mass vehicles of the brand "Lexus", "Toyota", "Hyunde", "KIA", etc.

According to experts, the main advantage of UNION is in innovation and constant search for the best technological solutions. On this indicator with brave japanese corporation No competitor may not be compared: annually on research in the field of oil filtering and an increase in the operation of individual elements (including internal combustion engines), the brand takes almost a third of the total income. This step, on the one hand, allows you to move forward the entire area of \u200b\u200bthe market, and on the other, does not give the company to lose relevance in modern conditions.

Dignity

• innovation in the development of new technical and technological solutions, the content of its own research center;
• careful compliance with world quality standards;
• the highest quality of oil filtration;
• very low marriage percentage achieved by hard operating control;
• large support for the retail market by issuing part of the manufactured products.

disadvantages

• very high price for the original product.

Oil filter, which in English is known as Oil Filter, is able to provide optimal cleaning of engine oil from a variety of impurities that usually fall into a total mass when carrying out circulation.

Such an oil beyond doubt can be attributed to one of the key elements of the high-quality lubrication system of all modern engines, which will work on the principle of internal combustion. Located a similar filter usually at the bottom of the engine.

Major varieties of oil filters

In the modern area of \u200b\u200bautomotive industry, such categories of filters are popular as:

1. Four-minded.
2. Partial reports.
3. Combined type filters.

Filters are full-flow possess the simplest design, they immediately skip the total weight of the oil through the filtration unit. The oil comes from a special pump, and after the composition is fed to all existing points in which the engine must be lubricated.

The devices of such a plan work on the basis of a special bypass valve, which is designed to regulate the pressure in the system. If the pressure for some reason exceeds the permissible parameters, this factor will be reduced using a special bypass valve.

Important! This is the main disadvantage of this design, since in the process of clogging the filter, the oil flow slows down significantly, and the internal pressure, on the contrary, increases. At the same time, the bypass valve is completely opens and contaminated oil falls into the system.

The presence of a bypass valve is able to effectively prevent the engine outlet due to the complete termination of the lubricant process. From the other side, dirty oil gets able to circulate. It is for this reason that the general state of the filter needs to be monitored.

A part-state-state filter oil purifies much longer as opposed to full-flow. In all systems where it is used, oil passes gradual cleansing, circulating simultaneously in two circuits:

• Straight, that is, from the pump to the friction site;
• Cleaning - from the pump to the friction zone through the filter.

When circulating oils of different contours, each other is mixed, which is able to provide high-quality cleansing of the lubricant of the entire engine entirely. Systems of such a plan are able to maintain oil in a relatively good condition, and for a rather long time period.

Important! The main advantage of filter data is that even with a strongly polluted filter, as well as under the broken valves, the total oil flow will not stop its movement, respectively, the engine will work as efficiently as possible.

As for the combined systems, they are usually created using technologies inherent in the two types listed above. The oil filter device provides a guarantee of high-quality oil filtration, as well as the maximum use of it.

Features Filter Design

All modern oil filters belong to the category of non-separable. Despite this, a lot of American and german cars They have a collapsible filter. Such devices provide the ability to replace the resulting filter element.

This is the main advantage of these structures, as the vehicle service is seriously simplified. In the case of such a filter there are not only filtering elements, but also a pair of valves:

1. CONSTRUCTABLE, Used to complete the reverse oil current.
2. The valve of the bypass, which provides the oil flow even with a serious clogging of the filter, and also fails the modified valve of the sample.

The bypass valve is able to work even when using oil with sufficiently high viscosity indicators, that is, with rather difficult filtering. This valve provides high-quality oil circulation even if the filter fails.

The core valve has the main task that is not to not be released from the filter at the moment when the engine does not work and that the circulation process and the engine lubricant starts immediately after launch.

The most common breakdowns of filters

Among the main signs of oil filter faults, such phenomena can be noted as:

• General engine worsening;
• When podagazaska appears black exhaust;
• Increase or reduced oil pressure;
• Flooding a special light bulb on the panel.

In addition to scoring the filter, the problem can be based on the loss of complete elasticity of the MEETING VALP. This factor is manifested in the fact that the controller on one of one of dashboards, as a rule, immediately after the engine is launched.

This happens for the reason that during the stop process, when the motor is turned off, the oil from the housing flows, respectively, during the startup process starts to work without the desired lubricant. This problem is solved quite simply. It is necessary to replace the oil filter or some specific filter element.

Important! Even with a slight suspicion of the filter output, the problem is strongly not recommended to pull. Any deterioration in the quality of the oil lubrication will lead to its overheating of the engine, respectively, its rapid wear. Neglecting timely repair work He will entail the formation of serious malfunctions and expensive overhaul.

Filter replacement frequency

Each modern filter has its own service life. Its significant excess threatens such problems as a violation of the quality of the intensity of purification processes. If the oil is not timely cleaned, the engine structural elements will be very rapidly worn.

Mann-Filter.

MANN-FILTER is one of the leaders in the production of liquid and gas filters of Europe. She releases filters under MANN, Wix Filters, Filtron, Purolator. Also, its products can be found in the composition of the EMO products of the set of brands.

MANN filters are supplied to consumers in a simple cardboard box of the corporate yellow-green colors. It can contain data on compatibility, and the phrase " oil filter"Written in 12 languages, including Russian and Korean.

We have in hand filters models W 811/80 and W914 / 2. The first is intended mainly for Hyundai cars and other Korean, Japanese and Chinese models, the second - for owners of VAZ cars and some rare foreign cars. Filters in Korea and Germany are produced, respectively, what the inscriptions both on the boxes and the filters themselves are.

Packaging is characterized by neat printing and assembly. The hulls of the filters themselves are carefully painted: 914/2 has blue colour, 811/80 - black. On the case of each filter, you can find a set of icons resembling the basic rules for its replacement and handling of spent materials, about the name of the model and the manufacturer. A barcode is also placed on the filter 914/2, and 811/80 has a protective plastic membrane that protects the insides from getting garbage before installation.

Also, the filter housings are equipped with a notch to facilitate installation and removal. The quality of rolling is high, paint damage in the zone of docking parts of the body is not. The filter for the VAZ has a simple flat sealing ring of rigid rubber, at the filter for the Hyundai ring from the softest material of the complex profile. The thread is made as accurate as possible, the surface is absolute smooth, without burrs and traces of mechanical processing. 914/2 filter can be seen inside the bypass valve, it is made of white plastics. It has a white elastomer from him with a white elastomer, and in 811/80 - brick-colored rubber.

Filtron.

Filters under the Filtron brand are also produced at MANN + Hummel plants. In this case, this is a factory in Poland. The packaging of this brand has its original design, made in yellow-black tones. Compatible filter models are indicated, there is a QR code with reference to the specifications page. Polygraphy neat, package assembly high quality.

The OP 564 model filter strikes compact sizes: its diameter is only 69 mm. These filters are intended mainly for Chevrolet, Daewoo and Suzuki cars. Case color black, color quality high. There is a stamp with information about the release date, performed directly on the housing. The reference to the country of production is on the box and on the filter itself. Directly on the building contains brief instructions for installation in English, Polish, German and Russian, as well as the names of the manufacturer and the filter model. The protective membrane or the cover on the filter is missing.

The quality of the rolling is high, the bin is painted in the color of the case with outdoor. The sealing ring closes one of the rolling planes and partially hides the place of attachment of the filter coil to the case. The sealing ring itself is a simple rectangular section and is deficiently installed, it should be trimmed when installed. It can be seen that the ring is made without the use of welding, compression. The quality of the thread is average, visible unevenness from coarse mechanical processing and acute outer edge. In the case you can see the black bypass valve and the elastomer in the corporal valve.

The filter of the OP 520 model is also packed in a box of corporate colors, but noticeably larger. Apparently, for this reason, instead of a simple Made in Poland on the filter itself and on the package you can see the intricate Made for MANN + Hummel FT PL. This model is designed for "classic" "Zhiguli", Fiat, Alfa Romeo machines and such exotic as Lotus. The rest of the differences from the "younger brother" at least. There are instructions for installing in four languages \u200b\u200band QR code. Rolling diagram and accuracy of the performance is similar. The protective cap or the membrane is absent. The sealing ring is also a loosely installed, with an inaccurate appeal, it can even be lost. The quality of the thread is good. You can consider the core valve from the black elastomer.

SCT-GERMANY.

SCT-GERMANY filters in Germany itself are known to a lesser extent. The address of the manufacturer on the package indicates Lithuania. On the Brand History page, you can also find a reference to the Filter Plant in Turkey and Production lubricants in Lithuania.

The Filter of the SM101 model is designed for VAZ front-wheel drive machines. Packaging quality is excellent. In addition to the data on the manufacturer and the filter model, there is information about compatibility with the MANN W914 / 2 filter and the list of basic models of machines for which this filter is intended.

One of the pieces of packing with perforation is intended for use as a marking-reminder of oil replacement. Color Filter Case Black, Coloring quality high. There is a stepped SCT logo on the lid and the testing date applied by paint. Also on the housing you can find the names of the manufacturer, filter models and compatibility data from 914/2 and Knecht OC102. It's nice that there are both pictograms and a text reminder about proper installation Filter, but only in English.

High rolling quality housing. The protective membrane or cap is missing. The sealing ring of the rectangular section is not fixed, but it holds tightly, a thin layer of lubricant is applied to it. The quality of the body is high, the traces of point welding under the sealing ring are noticeable. Inside, you can see the black bypass valve and the subtle membrane of the MEMPRESS valve, apparently, it is made on simplified technology. The filter element is poorly visible, but the traces of a large amount of glue-sealant on the top of the filter coil are noticeable.

Big Filter.

Domestic company Big Filter from St. Petersburg supplies oil and air filters On the conveyors of foreign automakers in Russia, in particular for the production of Volkswagen, Skoda, Peugeot in Kaluga. The company is deserved proud of victories in sectoral competitions and participation in the development of air filtration systems for foreign brands. And also the fact that its products are shipped to export and has a complete set of certification for working with foreign brands.

The GB-113 model filter is designed for installation on cars Audi, VW, BMW, Jaguar, Skoda, SEAT and some other issues of the 90s - early 2000s. Printing and package assembly high quality. The box contains the name of the manufacturer, contact information, including phones, data on the compliance and testing system ISO standards, QR code leads to the main page of the manufacturer's website.

The sticker shows the filter model, compatible models from MANN and FRAM and a partial list of models of machines for which this filter is intended. Case color green, color quality high. The enclosure shows the filter model, the manufacturer, its contact details, present pictograms with installation instructions. There is a stamp with a test date. The quality of the rolling of the body is high, there are no traces of point welding. The protective membrane or cap is absent. The rectangular sealing ring is kept due to elasticity tight enough, landing is smooth. The quality of the thread is average, mechanical traces are smoothed, but the edges of the thread have sharp edges. There are no sealant or glue. You can see the black membrane of the centenant valve and the spider by the bypass.

The GB-1156 model filter is packed in a box with a branded design, but another size. Fully preserved color gamut and design features. The filter model is also indicated on the sticker. A brief list of compatible models is present. The filter housing itself is very similar to GB-113: the same color and set of information. But here the other design of the sealing ring, it is from soft rubber Complex profile, installed on glue. It is possible to see the erect valve from black rubber and abundant traces of glue-sealant on the filtration coil next to the bypass valve.

"Nevsky Filter"

The filters of the brand "Nevsky Filter" also domestic production and also come from St. Petersburg. The brand is included in the large industrial group along with CJSC "Filtering Materials", the only production for the release of filter paper for filters in Russia. Thus, these filters are "maximum domestic". The company supplies filters for several domestic and Belarusian auto plants and engine manufacturers.

The NF-1001 model filter is packed in a box, which, according to the informativeness and colorfulness of the design, significantly exceeds any products of competitors. It can be seen not only data on the manufacturer and filter model, but also photos with the design of its filling with explanations, description of features and even data on the operating pressure of the activation valve. There are original manufacturer's number on VAZ nomenclature, a list of machine models for which this filter is designed, as well as some advertising of other products of the company.

The quality of printing and packaging assembly is high, there are cuts for re-fixing the valves of the box in the closed position. The filter housing is painted in white color, quality color is high, but there are traces of rubbing when packaging. The inscriptions on the housing are slightly lubricated, but readable. Unfortunately, their few: only the names of the manufacturer and the filter model. On the top of the case, a stamp with data on testing and the release date is applied.

The quality of the rolling is average, there are chains on the case. The protective membrane or cap is missing. The rectangular sealing ring is additionally held by small subset on the housing, but it is worthwhile due to the characteristics of the technology is not very smooth. The quality of thread processing is good. Inside, it is possible to consider a thin neat layer of glue-sealant for fastening the filter coil next to the bypass valve, the black membrane of the anti-valve valve is well noticeable.

The filter of the NF-1019 model is already designed for foreign cars, mostly Japanese and Korean assembly. The design of the box is in the same style as NF-1003, minimalist and with good informativeness. The color of the body is white, data is applied on the date of release and testing, the manufacturer and model, as well as the pictograms explaining the features of the filter replacement process. Rolling quality high. Rectangular sealing ring is glued. Inside the filter you can see abundant traces of glue-sealant on the top of the filter coil, the black plastic bypass valve and the black membrane of the anti-industrial. The quality of the thread is high, the traces of mehowing is not observed.

The product assortment contains filters not only the traditional design of Spin-on and interchangeable cartridges, but also exotic as NF-1020P. This filter is intended for machines with very common diesel engines Cummins 2.8 ISF, for gas production machines and significantly different from the usual. First, he has a plastic case, and secondly, completely unusual form and seal scheme. The quality of the manufacture is high, nor inclination, no distortion of geometry is noticed, seals are in their places, the thread is absolutely smooth. Contact surfaces are made with a homogeneous roughness. Marking on the filter itself is minimal: only the manufacturer and model. Inside you can see small traces of glue. Packaging such an unusual filter is completely typical, it is allocated to the size and the fact that the information is applied directly to it, but on the sticker.

Modern hull oil filter (cartridges are used on a number of cars - only the paper filter element itself is replaced by maintenance) consists of the following nodes:

• Housing. This is a metal cylinder with a spinned lid, in which the threaded seat is located (it is the output of the filtered oil) and the holes for the oil supply. For a particular car, two geometric parameters are important: the type of thread (metric 20x1.5 on most cars, on some, in particular - vases, inch ¾ UNF) and the diameter of the sealing ring, which should clearly fall on the cater's catering plane. Filter height U. different manufacturers It may change, and in most cases it is better to choose a larger oil filter: This means that a filter element is installed with a larger area, which will provide a smaller resistance (this is especially important when the oil viscosity increases) and smaller contamination rate. But need to be taken into account and the design of a particular car - a long filter may simply not fit into motor compartment, rest in the nozzles and so on.
• Filtering element. This is a corrugated paper with a predetermined pore size (usually several dozen microns), through which the pump is pumping oil pump. The filter resistance and cleaning quality depend on the filter element and its porosity. Tighter paper - the choice of motorists using low-viscosity (5W30, 0W20) synthetic motor oils for cars operating on more dense oilsThe smaller resistance is required - from here either reduction in the quality of filtration, or the need to increase the size of the filter element. And indeed, on many modern passenger cars Oil filter is several times less than the classic "Zhigulevsky" - with the same filtering, there is no need to create large-sized filters.
• Bypass valve It serves to protect the filter element from destruction - with increasing pressure difference before and after the filter, it triggers, passing oil bypass to avoid the destruction of the filter. The positioning valve calibration is always a compromise: too soft will open too early, opening the path of untreated oil with each cold start, too tough in the same conditions can cause the filter element curtain break. Calibration is set in features concrete Engine, and including the viscosity of the engine oil recommended by the manufacturer.
• Corporate valve You can see through the holes in the oil inlet. This is a flexible rubber curtain that does not allow oil after stopping the engine to flow back into the crankcase. Thus, the time required to set the pressure in the system when starting the engine is reduced. A lesserless high-speed valve will noticeably increase the oil starvation after the night parking, too hard will increase the total filter resistance.

To increase the oil filter resource, a number of manufacturers enters into its design an additional coarse filter. Usually in its role there is a magnet designed to keep metal dust, inevitably generated during engine wear. But is it necessary? For a new engine operated on high-quality motor oilThe pace of mechanical wear will be negligible, and there is no need for an additional compartment of metal. A worn motor, especially repeatedly repaired using low-quality cheap spare parts, it will be much more necessary.

In this ranking, we practically did not use the usual combination of requirements for the value of the price and quality (except for original filter, But he was too tangible from the general row). In the end, in the total cost of oil replacement, the costs of the filter are extremely small share, and its high-quality work for 10-15 thousand mileage means much longer. Considering the specified facilities specified in the description of the presented goods, you can make the best choice.
