Each car owner, after a certain period of time, faces the need to replace the automotive oil. As the market is presented big choice different species from manufacturers such as: Shell, Mobile, Motul, Liquim Moth, Castrol, etc. - The choice is not easy. To do this, you must compare the range and select the oil that meets the requirements of your car.

Motor oil parameters

The main parameters of oil that will help the driver to make a choice, three:

Oil viscosity is its aggregate state (liquid, thick, solid), depending on the temperature. Typically take wide ranges of temperature - from -30, up to +100 degrees Celsius. This is one of the most important indicators, since the viscosity is determined by the force of friction with which the engine cylinders interact, and, as a result, the motor wear rate.

An alkaline number is the content of ions in automotive oils that neutralize the acids and oxide during the engine operation. Measure in con / g. The greater the value of this parameter - the longer the oil will be able to neutralize the harmful acidic environment

The combination of these indicators determines the quality of the car and its focus: additional protective properties or the best engine performance indicators. Currently, according to the rating "Auto - Review" for 2014, the most popular among them are products of companies and.

They are similar: these are synthetic, high-class oils, with its place in the market.

From this approval follows the question - "Which one is better quality?".

To answer it, we analyze the viscosity, an alkaline number and the content of different ions.

Analysis of chemical properties of Shell and Mobile oil properties

Chemical analysis and alkaline number The chemical composition of the automotive oil is determined by its additive elements, the content of which is measured in milligrams per kilometer of the run. These elements include calcium, phosphorus, zinc, boron, magnesium ions. The content of calcium ions, the indisputable advantage has mobile oils or catcher.

It contains more than 2000 mg / kg, compared with 1354 mg / kg of shell oil. The amount of magnesium is approximately the same. The content of phosphorus, zinc, boron is also more in production Mobile, but it is impossible to say that the difference between these indicators is large - on average, the deviation reaches 10%. However, the shell oil contains barium 2 times more than its competitor - 14 mg / kg. The unarmed look is noticeable that the oil of Mobile is significantly ahead of the shell on the content of different ions. This quantitative advantage is determined by a higher alkaline number: an average mobile oil demonstrates values \u200b\u200bin a region of 9.5 mg of con / g, while the shell oil has about 5.40 mg of con / g. An interesting feature of Mobile oils, which significantly improves the functionality of the product is the content of molybdenum. This metal protects the engine from wear and reduces the friction effect. The mechanism of its action is simple - it fills the microcracks, increasing the smoothness of the surface. The average molybdenum content in mobile oils - 150 mg / kg.

Despite the visible lag of Shell, with respect to quality composition, empirical experience shows that compared oils show equally good indicators in terms of protecting the engine from wear. The only significant difference between them is the difference in protection for aluminum and steel parts, which was studied due to the trace concentrations of iron.

Mobile oil shows top scores When working with an aluminum engine, and shell - with steel. Also, with practical use, these oils show almost the same ability to protect against acids and various oxides. Despite the fact that the shell oil has a smaller alkaline number by almost twice, compared with Mobile, it retains the permissible level of acidity at no worse. A comparison of physical properties has already been said that viscosity is one of the significant parameters of the automotive oil.

Shell and Mobil at low temperatures comparison

In order to compare the products of Shell and Mobile, it is necessary to trace the behavior of these oils at low temperatures and high-temperature conditions. The tests were revealed that shell oil is the most thick at 100 degrees Celsius, that is, with operating temperature Engine. It exceeds not only synthetic mobile or catcher, but also semi-synthetic Motul or G-Energy samples. Low-temperature properties, in a compared pair, are excellent. Even at a temperature of -27, oil retained a liquid aggregate state, slightly thickening, and provided stable work Engine and fast running motor - within 3 seconds.

Oil consumption "On the Ugra"

This parameter reflects the amount of oil to burn in car Engine, for its optimal work. Accordingly, the flow rate determines not the last, as of importance, the indicator is economy. Shell, in this respect, demonstrate enough high flow. Without adding oil, the engine is ready to work up to 4500 km, after which the level begins to fall, and, to 5000 km, will fall below the permissible minimum. Mobile - more economical oil. The difference between indicators is not so significant - its consumption is 3% lower than that of Mobile products. Therefore, we can assume that Shell and Mobile, in this regard, do not demonstrate significant differences. The figures say about it: average flow Fuel, when using Mobile oil - 11.32 l / 100 km, and Shell - 11.39 l / 100 km. Each one in all basic parameters, the functionality of Shell oils and Mobile keeps at a high level. Their chemical composition and physical properties provide good engine performance and do not cause problems.

So all the same Shell or Mobile?

Both of these oils are good, but it is important to determine the optimal zone of their work. If the car is operated in conditions when it is necessary to provide high-quality fuel to a machine, then the car oil must have a large number of additive elements that will provide an increased alkaline number - like mobile oils. It is also necessary that the engine of the car and the oil most suitable for each other. As mentioned above, steel mechanics will have to taste more to taste, and Aluminum - Mobile.

After analyzing all these factors, the motorist needs to make the choice between these products. The operating conditions of the machine, the quality of gasoline, climatic conditions - all this affects the operation of the oil. Therefore, the answer to the question: "Who is better, Shell and Mobile?" It will be completely different in different situations.

Engine oil used internal combustion, Performs several tasks. It cools the details of the motor, prevents the formation of corrosion, reduces the friction of moving parts, thereby slowing down wear.

Since there are many types and varieties of engines, then the engine oils are no less. After all, the work of different motor systems is designed for certain working conditions. To determine what butter to use during the operation of the car, for example, shell or mobile, you can independently, if you know the principles of classification of oils.

About manufacturers Mobile and Shell

A significant number of car owners have far from a complete picture of the engine operation at different temperatures, as they do not show interest in the chemical composition of the oils. They are based only on reviews of other drivers and recommendations of specialists.

Both concern has long been popular with the world market. The first, North American, exists for more than 120 years. For such a term, it has significantly strengthened, absorbed several less significant competitors.

In 1999, it was associated with a large English company Exxon. In terms of sales, the corporation has been in second place in the United States for a long time, while maintaining its place in the top five world leaders.

Shell, which is the largest manufacturer of the car, the product of the joint production of the two countries - the Netherlands and the UK. It leads to the world market in terms of sales. Created at the very beginning of the 20th century.

Products manufactured by Mobil and Shell Helix.High quality. At the same time, the first manufacturer contains compositions that reduce consumption.

The second releases a car that allows you to run engines to any heat without any problems. At the same time, they reliably protect the motors. In addition, in the line of this company there are GTL oils.

General information about Motor Mobile and Shell Helix

The assortment of both producers have a mineral water. The process of its manufacture - primary (selective) purification of the composition from paraffins present in it.

With hydraulic processing mineral oils Their characteristics are improved. They are better lubricated the details. Substances that are pollutants are very small in them.

Also produced lubricants with a special viscosity, which is provided by the hydrocracking process. Such formulations are present in the range and Shell, and Mobile. They are divided into mineral, synthetic, semi-synthetic.

All this products are characterized by stability with respect to oxidation, has good viscosityThey do not have harmful impurities. GTL oils have the highest quality. There are no compositions of this level at the mobile.

Both Mobil and Shell Helix are manufactured for diesel and gasoline engines. In addition, there are universal compositions that are suitable for working with those and other DVS.

By purchasing engine oil, you should always control the rate of kinetic viscosity. If the viscosity is high, then it can be poured into the motor even if the summer heat reaches tropical values.

In automas, intended for internal combustion engines, there are always a variety of additives that improve its properties. In recent years, more popular becomes synthetic oils. They contain chemical compounds that provide higher operating performance.

Motor Oil Requirements

When choosing an oil, it is worth relying on the following main parameters:

Viscosity is an aggregate state that is completely dependent on temperature. This indicator is considered important, as it is responsible for the power of friction with which motor cylinders work.

Alkaline number - indicates the volume of ions, which in the process of functioning are eliminated by oxides, cope with wear and show detergent. The higher the indicator - the longer the oil will be able to cope with its task.

All these nuances speak of the quality of oil and its orientation: improved motor performance or additional protection. And Mobil, and Shell has lubricants optimal in all indicators.

Review and properties of additives in Shell Helix and Mobil oils

When analyzing the chemical composition, the alkaline indicator is to pay attention to first of all, as it is the determining diversity of additives. They are ensured by the presence of ions:

• zinc
• boron
• calcium
• phosphorus
• magnesium.

There is always more calcium in Mobile - 20 mg / kg (about the presence of the same level of calcium ions in its products declares Castrol).

In the production of shell calcium less, no more than 13.55 mg / kg.

The remaining elements and compounds are present in approximately equal ratios. However, Mobile has a little more.

At the same time, the shell oil marks a larger volume of barium - 15 mg / kilogram. In the mobile, this indicator is 9.5.

But in general, in Mobil compositions, the number of major additives is higher than in Shell. In particular, they contain molybdenum (MO), which improves the lubricant effect. This metal is designed to protect the parts and engine nodes during the friction process.

When the motor operation, microcracks are formed in detail. They are filled with particles of molybdenum. Mo has high strength, thanks to him, the service life of the motor is extended. In a kilogram of Mobile oil there are 150 milligrams of molybdenum.

Consumption for avar

When the engine is running, a process called an oil burnout occurs. This parameter indicates the volume of the car that burns into the engine. It can be called and an indicator of economy.

There are extremely permissible flow rates when ugar. In such cases, the smaller the car is spent, the more economical it is considered.

All Mobil products in this respect exceeds Shell Helix. The magnitude of the difference in the ugar is approaching three percent. But this indicator is not a significant value based on which the choice can be made.

Shell shows increased flow. Without an attraction, it will work 4500 km, then the oil level will fall, and the 5000 km falls below the permissible values.

Mobile is a more economical option, but the difference between them is not so sensible - about 3%. This indicates the following data:

1. On average mobile oil, 11.32 mg is consumed at 100 mileage kilometers.
2. Shell consumption is 11.39 per 100.

Physical indicators and chemical composition of oils are responsible for the proper operation of the engine.

Work under reduced temperatures

Lubricants were tested and in cold conditions. At the same time, temperatures were brought to minus 30 degrees. Studies have shown that the oils from the company Shell at 100 ° C are not diluted.

According to this indicator, it exceeds its competitor, as well as semi-synthetic samples from G-Energy and Motul.

The properties of the compositions of both brands during the cold season remain at the initial level. Even under 30 frost Shell Helix and Mobil retain viscosity indicators, providing start for three seconds.

What is still better, Shell Helix or Mobile?

The great presence of additives in the car is only an indirect factor of impact on ensuring the operation of the engine. During the tests, the shell oil indicators did not inferior mobile.

Differences are present only if there is a speech about "soft" details, that is, made of such metals such as copper and aluminum. But in steel engines Shell show advantages.

Both options have their advantages, but it is necessary to determine the optimal area of \u200b\u200btheir work. In a situation where, due to the features of operation, there is no possibility to pour into TC proper fuel, a large package of additives must be made to the oil to increase the alkaline number, - Magil brand is suitable for this criterion.

It is also important that oil and motor are compatible. As noted, the steel technique will fit Shell, and aluminum - Mobil.

Climatic indicators, quality of fuel, as well as the working conditions of the car - all this affects the operation of the oil. Therefore, the answer is which choice is to be absolutely different in different conditions.

Any motorist, not even having a lot of experience, understands that the presence of a lubricant is simply necessary for the car. Without such a liquid, mechanical nodes and aggregates simply fail, while the car will not even leave. In fact, the aspect of the choice is extremely important, only a quality substance, confirmed by the manufacturer's guarantee and the manufacturer permitted by the manufacturer should be purchased. vehicle. If you buy good oilThe interacting mechanisms will function for a long time and freely function, glad the owner of the car. In the material below, we will consider the goods of brand companies, learn how oil is better - Shell or Mobile, comparing them before. High-quality lubricating liquids not only reduce friction between the elements of the system, but also oppose oxidative processes, cooled hot parts.

Comparison of motor mobil oils, Shell or Castrol.

Motor oil selection criteria

If the motorist does not know what to rely on when choosing a lubricant, it should, first of all, to pay his attention to the product of the foreign manufacturer. As a rule, all motor liquids You can classify. Substances are different from each other in composition, in stores you can purchase mineral lubricants that are considered basic (they are created by selective purification by removing paraffins by solvent); minerals that were disturbed by hydraulic processing; As well as lubricants that have the highest degree of viscosity.

Motor fluids that have the highest level of oxidative stability, as a rule, have excellent viscosity, there are no paraffins. This class includes exclusively basic synthetic fluids without harmful impurities of sulfur and metals.

Manufacturers are also created, which are based on plant extracts. Such substances have a high level of resistance to the outer film from the oil. Their main advantages are the possibility to rinse the power unit, showing good thermal and antioxidant functions. It is believed that the most best Oilwhich exists today is a lubricant created by the GTL technology. The release of this substance is engaged exclusively to Shell, in which this lubricant is called Pennzoil.

Differences of oils for chemical properties

If the car enthusiast doubts what oil is better - Shell or Mobile, it must take into account that in almost all modern engine fluids there are substances of several categories described. In addition, in them, thanks to which you can hide the shortcomings of basic lubricants. The best engine substances are oils: Shell Helix, Mobil 1, Castrol, moth moth. According to many specialists, the goods produced by Total and Zeke, the goods produced by the company, not worse properties, however, when choosing it is extremely important to take into account the quality of lubricants.

The motorist when choosing should take into account the lubricating fluid qualities, the temperature range of the work, the possibility of the substance for a long time to function without losing paramount properties, hygroscopicity, polarity, the level of evaporation. Not in vain between leading companies for the production of motor liquids, there is a chemless struggle for the championship, each plant is trying to invent such a liquid that would have the optimal indicators regarding all existing qualities. However, allocate only one single substance is not yet possible.

The product under review is purchased by the owners of both injection, and the machines are equipped with both boxes with machine guns and mechanics. Due to the mass of the differences between the types of engines and the PPC, there is no possibility to highlight only one single tool, optimal lubricant It should also be bought and depending on what region or climatic belt is operated auto. Moreover, an important indicator For many, the price of the finished product becomes.

If you think about what oil is better - Shell or Mobil, it should be noted that Exxon Mobil is part of the leading auto chemical manufacturers widely recognized by car owners from around the world. Regularly improved synthetic lubricants are most popular. If we compare the oil of Shell and Mobile, it will be necessary to take into account the fact that Royal Dutch Shell has a powerful basis, owning a variety of subsidiaries and refineries. At the peak of Glory, synthetic and semi-synthetic motor fluids, which have traditionally high quality are almost always located.

Many motorists often cannot figure out which oil is better - Mobil or Castrol. As practice shows, the product producer of Castrol lubricants enjoys with great demand among compatriots. Russians are trying to acquire the synthetic and semi-synthetic substances of Castrol, ideally suitable for power units installed both on passenger and on cargo cars, on motorcycles. Analysis of chemical properties car oils These manufacturers do not allow to name only one unprecedented winner. All described lubricants of these firms are in demand among motorists of Russians. Due to the ever-growing competition, lubricants are regularly looking for new technologies, improve the quality indicators of their goods.

Principle of Motor Lubrication

Compared by Mobile and Shell oils, we can conclude that both lubricants have excellent quality indicators, which gave them great popularity among motorists from around the world. True, Castrol oil has no worst qualities.

Before you buy one or another lubricant, you need to pay attention to the climatic conditions in which the car will be operated. With the active work of the vehicle at the time of the combustion, any fuel is converted to Nagar. Any residual deposits do not disappear without a trace, they remain on the walls of the engine elements. Essence of work lubricants - Significantly reduce friction between the parts of the engine, neutralize the oxidation reactions, wash off harmful precipitation from the elements of the system, which causes the need to periodically change the engine oil.

By buying lubricant, its environmental friendliness and safety should be taken into account. Regarding the season, you should choose summer, winter or all-season fluid. On sale there are always motor oils intended exclusively for a particular type of engine, as well as universal. Of course, in the presence of sufficient amount, it is recommended to give preference to the oils of the companies Shell or Mobile (if they are original) or cheaper analogues produced by Total plants, LUKOIL, TNK.

Main differences of oils

To understand which oil is better - Mobile or Castrol, it is necessary to check it on a variety of factors. Regarding different criteria in the leaders are completely different lubricants. When considering such a factor as the most economical fuel consumption, the goods are leading the goods of Shell. According to studies, people who prefer the goods of this brand can save about 8% on the fuel used.

Often comparative analysis affects the stability of the oil film, motorists are often interested in comparing lubricants at low temperatures. Here the unprecedented leader is the product of Mobil. Such a lubricant increases the service life of the engine, since it has a beneficial effect on reducing the wear of the system elements. True, it negatively affects the power of the power unit due to the increased friction coefficient that appears due to the resulting film. In the lubricants of Shell and Castrol, quality data is somewhat less pronounced.

Russian experts regularly check motor lubricants For many indicators. For example, with respect to kinematic and dynamic viscosity, all oils have excellent indicators. As for the presence of additives, the lubricants of Mobil, Shell, Castrol lubricants are defeating (at the same level of oil firms and Total). By density, all oils correspond to the stated indicators. If we speak exclusively about anti-wear properties, you should give preference to lubricants Mobile and Shell, the catcher in this plan is slightly weaker.

Given the consumption of the avgar and all the above criteria, Russian specialists note that all the above firms supply oil to the market, on which a motorist without unnecessary problems will be able to drive about 300 thousand km. Test results showed that normal conditions Shell lubrication operation, Castrol and Mobile are suitable for use. Only with high loads on the power unit of the machine or high temperatures should be paid to the properties of a particular substance.

Conclusion

So, it is impossible to distinguish only one oil, which would have been excellent characteristics in all indicators. The optimal substance should be selected according to the temperature and loading regime in force aggregate. The accounting should also be taken by some specific features of the vehicle, sometimes the use of high-quality fluid is impossible due to a certain amount of the gap in the details, which directly affects the efficiency of fluid operation. It should be purchased exclusively that product that meets the technical definitions of the manufacturer's plant, as well as the personal preferences of the motorist. The main thing - the working substance must be original, not fake.
