One of the main factors affecting the engine resource internal combustion, It is the quality of engine oil and its replacement. To understand which oil is better to pour into the engine of the fiberboard, you need to prevent the specifics of its device and work well.
Specific requirements
Most modern motoblocks (can be studied in this article) are equipped with four-stroke gasoline engines that do not have in their design of the oil pump.
The bottom head of the connecting rod, which is a sliding bearing, is lubricated by the oil with a special protrusion on the bottom cover of the connecting rod, the native crankshaft bearings, the gas distribution mechanism and the cylindropional group are lubricated with the splashes.
Also these engines have an unstable temperature due to air cooling.
For more information about the 4-tact engine, see the video:
Thus, the engine oil for 4-tact engines of motoblocks should meet the following requirements:
- Low kinematic viscosity In a large temperature range, it is necessary to avoid oil starvation when driving the engine to operating temperature.
- The use of viscous oils in engines that do not have lubricants under pressure can lead to a burden on the surface of the connecting rod cervix followed by metal tooling at this place and engine jamming.
- The stable composition of the package of anti-friction and native additives will allow the oil for a long time to maintain its properties with regular cooling heating cycles during the operation of the motoblock.
- The high strength of the oil film is necessary to protect the cylindrophone group from the jackets when the engine overheating during hard work in hot weather.
- The detergents provided by the appropriate package of additives should counteract the fallout of the precipitate and the lacquer formations in the engine pallet and on the surfaces wetted surfaces.
- Low coking is relevant for engines with air cooledSince the oil falling into the zone of piston rings is heated in this place to a temperature of 270-300 degrees.
- Nagar's education will lead to the loss of mobility of piston rings and reduce compression with simultaneous oil overrun.
Based on these requirements, it is possible to describe the technical requirements that must match the oil for 4-stroke engines of the motoblocks, so:
- The class of high-temperature viscosity on SAE is not more than 30 in temperate climates, 40 - in hot. Low-temperature viscosity index - no more than 10W. These requirements are satisfied with the common oils of Types of 10W30, 5W30, 0W30, 5W40, 10W40 (the last two - at temperatures of 30 or more degrees).
- Pure summer options - SAE 30, SAE 40. It is necessary to carefully read the characteristics of the oils: a number of specialized oils for garden equipment with a viscosity of 5W30 are intended solely for winter use.
- The base of oil: synthetic or semi-synthetic, as in the specified viscosions of viscosity, mineral oils are practically not found. In addition, they have significantly worse stability compared to synthetics and semi-synthetic.
- A number of manufacturers of lubricants have a special line of oils for garden equipment on a mineral basis, in this case the cheapness has reverse side In the form of a frequent replacement.
- Quality class according to API (a complex parameter that defines antifriction, anti-plating and detergent properties of engine oil, as well as many other parameters) not lower than SG.
It should be understood that all the requirements for motor oils for motor-blocks, and the common automotive oils are responding, its consumption and the amount of car formed when long operation In the air cooling engine.
For this reason, although this material is considering specialized lubricantsIf there is no possibility of acquiring them, you can always use the corresponding automotive engine oils described.

Replacement
Replacing the oil in the motor motor motor is carried out with the frequency indicated in its operating manual, it is usually 60-80 hours. The specified interval should be reduced under severe working conditions or the use of cheap mineral oils.
Before replacing the oil on the motoblock, place it so that the engine is horizontally, and warm the engine so that the oil is better fastened. Then turn the plug of the oil-coaling neck and the drain plug, substituting the tank of the appropriate volume under it.
Be careful not to burn hot oil.
Waiting for the moment when the exhaust oil stops dripping, wrap the drain plug in place and pour into the carcase through the clean funnel fresh oil, guided by the passport volume and labels on the dipstick of the oil-coaling neck.
Since the engine lubricant is carried out only by spraying the oil from the crankshaft, strive to always maintain the oil level on the Maximum label. Low-locked filled holes without probe must be filled with oil until it appears on the thread.
If the motor-block engine is equipped with a downward gearbox, do the same operations with it. Most often the gearbox does not have oil affectionAnd in order to measure the desired amount of oil, use the small capacity of the known volume.
Whatever the motoblock worked perfectly perfectly, it must be maintained correctly and operated. Oil is a key factor that provides engine operation. Which oil to fill in the engine of the motor-block, let's try to figure it out on this page of the site.
The most correct recommendation on the selection of oil will be the recommendation of the engine manufacturer for the motoblock. Therefore, you will get acquainted with the instructions for the operation of the main engine manufacturers to the motoblocks and make excerpts from the instructions.
The choice of engine oil, as well as any other type of oil, depends on the two main parameters - operational category and viscosity class.
Classification of varieties of oil
Classification of the API on the operational category (American Oil Institute). See more detail
Classification of viscosity oil varieties
SAE classification (automotive and transport engineers society). See more details
If briefly:
Winter - With the letter W (Winter). Oils satisfying these categories - low-viscosity and used in winter - SAE 0W, 5W, 10W, 15W, 20W, 25W
Summer - Without alphabetic designation. Oils that satisfy these categories are highly viscous and used in summer - SAE 20, 30, 40, 50, 60.
All-season - At the moment, universal oils, which are also used in winter and summer, are most widely distributed.
There are such oils with a combination of winter and summer series: 5W-30, 10W-40
In winter, use oil with a smaller SAE numeric value (less viscous), and in summer - oil with a large value (more viscous).
Oil with several viscosity indicators has comprehensive stability in seasonal and temperature changes. For example, oil type SAE 10W-30 is suitable for use as a all-season. At low temperatures it is equivalent to viscosity oil Sae. 10W, and in the process of work possesses the same lubricating properties as SAE 30.

Periodicity of oil replacement in the engine of the motoblock
- check the oil level by installing the engine on the horizontal surface, wait until it stalks into the crankcase.
- when replacing the oil, drain it on the hot engine, unscrewing, drain and filling covers
- do not use additives and supplements to the oil
- get rid of the used oil in such a way that it would not harm the environment, do not drain it to the ground, do not throw in the garbage tank, the best option is renovating the oil in a closed container to the local processing point.
Please note that there are such engines in which an additional gearbox is built, in which periodic oil change is also needed. Here is an excerpt from the user manual for the Honda engine.
Purchasing a motoblock, it is necessary to remember that its durable work depends not only on the replacement supplies, parts, tightening the necessary nuts, but also from timely replacement of oil in the fiberboard.
From how correctly choose engine oil for motoblocks, the durability and efficiency of the equipment depends. The question arises which oil to fill in the engine of the fiberboard, how to replace it or check the level.
1 Motor Oil Functions
With each technique, including with motor blocks, complete when selling there is a passport and instruction. Manufacturers are always in the instructions recommend that kinds of oils that will allow the technique for a long time and do not break.
It is necessary to know that during the operation of the motoblock, the engine oil performs 4 functions at once:
- cooling;
- lubricant;
- cleaning;
- seal.
When the engine is operating with air-cooled, the lubricant is burning and remains on a hot cylinder, after which the smoke exhaust is formed. Deposition of resinous substances Carefully affects the contamination of some details And their lubricant is complicated.
Using the motoblock you need to choose a lubricant, leaning on the climatic zone.
For example, when using a SAE 10W30 lubricant at a temperature of equal to 5 ° C and above, it will be much higher, and the engine breakdown will occur much higher. Summer lubricating fluids undesirable at air temperature below 5 ° C. Such use leads to a difficult engine launch and damage to the cylinder mirror.
1.1 Classification of varieties of oil according to the degree of viscosity
The degree of viscosity of motor oil varieties is customary to be classified according to SAE (society of engineers of the automotive industry).
Quality wash oil MPa - 2.
Namely:
- Summer varieties - oils related to this category are applied in summer, have high viscosity And without alphabetic designation. These include: SAE 20, 30, 40, 50, 60.
- Winter varieties - these oils are used in the winter and have a low viscosity. The letter designation of this variety W (Winter). These include: SAE 0W, 5W, 10W, 15W, 20W, 25W.
- All-season varieties are the most popular currently, as applied in summer and winter. They are denoted by a double combination: 5W-30, 10W-40.
In addition to differences in lubricants for seasonal features, They are divided according to the composition of two types:
- mineral;
- synthetic;
- semi-synthetic.
All oils are divided into lubricant for both 2-stroke and 4-stroke engines. Usually 4-stroke air-cooling engines are installed on the motoblocks. In such engines it is necessary to pour only 4 clock oil.
The air cooling motor during operation heats up more than water-cooled engine under the same operating conditions. Therefore, the filling fluid should have low evaporation and high thermal acid stability. Same modern oils must have environmental security, those. The amount of smoke and toxicity of exhaust gases is controlled.
Since waste is often simply burned in boilers or steam generators, they should not contain in themselves the components forming toxic compounds when burning. In a motor-cultivator, which works on gasoline, and does not have instructions, it is better to cast 4-stroke oil 5W30 or SAE30.
In winter, it will be preferable to winter or transmission oil, for example 0W40. But for such quality will have to pay. It is not worth saving this, because high-quality oil affects less engine wear and on its durability.
2 What kind of motoblock: diesel or gasoline?
Aggregates with a diesel engine are designed mainly to work at large areas of the Earth. This type of engine is able to produce high traction effort due to working on low revs. They are designed for a much greater resource, rather than gasoline.
Therefore, their work can be done much longer without stopping. It is impossible to give a diesel engine to idling, because it leads to his breakdown. Sometimes you need to upload for 3-4 hours the unit on full power. This will allow to extend the life of the motoblock.
The main advantages of diesel motoblock:
- Convenient maintenance and operation, since there are no candles and magneto, as well as there is no carburetor that you have to constantly adjust.
- Maximum grip with earth thanks to high weight.
- Cooling is possible either by air or water. Gasoline engines are deprived of such a variety.
- The fuel flow rate can vary from 2 to 5 liters per 100 km, based on the power of the unit.
- The engine operation is provided by stable turns due to increased traction effort.
The price may scare when buying a diesel motoblock. But it is worth considering that it consumes fuel less than gasoline, and the diesel is cheaper than gasoline. This acquisition pays off over time.
2.1 Gasoline Motoblocks
The motoblocks of this class are ideal for the processing of small land plots. In the gasoline engine, fuel ignition comes from the spark that is produced from the spark plug. Such motoblocks are very maneuverable and lungs.
For gasoline engine Suitable any gasoline used in modern cars. They can only work on high revolutions. Repair and maintenance is much cheaper than diesel engines.
The main advantages of the gasoline engine:
- It is possible to start it under all weather conditions without an electric starter.
- Reduced noise level.
- Significantly less vibration when managing.
Basic the advantage over the diesel engine is a relatively small cost. They are suitable for small sections (20-30 acres), as they do not withstand large loads. Diesel engine It will be optimal in all other cases.
2.2 Replacing Oil in Motoblock
There are many different opinions about how often it is necessary to change the oil for motoblocks. But it is necessary to rely in this case on the manufacturer's instruction. If there is no instruction, you can change the lubricant common among users in the manner.
The first replacement of the oil in the fuel is made after running the unit. Engine running and all its nodes must be carried out at idle. Before starting the engine, you need to make sure there is a lubricant in it. When buying an aggregate, its engine can be dry at all.
After an hour of operation of the engine, the first replacement of lubricant is performed. Next replacement - after 5-6 hours of operation. It is recommended to change the oil in the motobock every 40 hours of operation, which is much more likely than in the car. After winter period Replacing the lubricant is required. It does not matter how many hours a motoblock worked if his lubricant became viscous, darkened or a strong smell of Gary proceeds from it, then it should be changed.
Before changing the oil, you need to warm the fuel. It is necessary in order for the lubricant to become more fluid. The motoblock is installed in a horizontal position. A drain plug is twisted and the old liquid from the engine crankcase is removed.
After that, it is necessary to tighten the plug in the drain tank back and make a fill of lubricating fluid through the bay neck. Check the oil level can be controlled by a plug. The level should be between the MINIMUM and MAXIMUM marks. Then the plug is twisted completely.
To fill and check the lubrication level in the gearbox crankcase, install a motor-block on a flat surface and clean the gearbox housing in the area of \u200b\u200bthe fuel hole. After that, loosen the bolt bolt. If the level is normal, the oil will begin to flow from the hole. If this does not happen, you must unscrew the bolt completely and pour oil into the gearbox until it flows out of the hole.
An important nuance is the proper condition air filter. After all, without a air filter or with a filter, but without the required oil level, the engine cannot be launched. For tall lubrication, you need to unscrew the nut on the filter cover, Pull the filtering element from the pallet, pour the oil to the level of the mark on the oil bath. Set back the filter element and spin the nut.
Based on the above, before buying an oil, it is necessary to understand several important points:
- Determine the oil use season.
- Purchase special additives to enhance the properties of lubricating fluid.
For proper choice The product is ensured by a long service life of the unit and improves its work.
In the two-stroke power units, the lubricant dissolves in a combustion, and then burns simultaneously with it. Oil for four-stroke engines is significantly different from the analogues used in two-stroke engines. It better and maintains its useful properties for a long time.
It includes a large number of special additives (at least 25%). Unlike other brands, there are no increased requirements for the level of ash content and smoke. Their level reaches increased indicators (ash content - more than 2%).
Features of the lubricant system of the two- and four-stroke motor
Many consumers are wondering what is the difference in 4-hour engines and two-stroke. Carter four-stroke power aggregate A predetermined amount of lubricant is constantly supported. From there it is supplied to the lubricant system under the influence of the oil pump.
As a result, oil films are formed on the pistons. In this case, there is no friction when it is slipped along the walls of the cylinders. In order to prevent the penetration, oil fluid into the combustion chamber, the oil-chain rings, cutting the lubricant, directing them back to the crankcase.
The lubrication system of two-stroke engines is based on mixing fuel with motor lubricant in the proportion of 50/1. Modern car oils have a unique property of mixing itself. With a lack of a substance for the full lubrication of the operating surfaces of the cylinder, the power unit works "dry". At the same time, the overall engine resource is sharply reduced.
More powerful two-stroke motors more than 40 liters from. equipped with a special tank for car Oil. It produces automatic dosing and mixing the mixture in the correct ratios.
The disadvantage of 2-stroke lubrication systems is to reduce the combustion efficiency due to the content in gasoline of oil particles. Opening inlet I. exhaust valves Also negatively affects the performance of the force aggregate. In this case, there is a large release of unburned mixtures into the environment.
Differences of 2 and 4-stroke oils
In connection with the presence of constructive differences in lubricating systems of these engines, the requirements for lubricant materials differ significantly:
- For two-stroke engines A prerequisite is the ability of the most complete combustion of oil. At the same time, the minimum amount of nagar (soot and ash) is formed.
- In four-stroke engines, the main requirement for engine oil is a long-term provision of lubricating effects by storing the beneficial properties of the material used.
Previously, the method of simple refineries was used in the manufacture of lubricants. The resulting product was suitable for lubricating parts and nodes, engines of any kinds. Them specifications We satisfy the requirements of motors with a small power, low friction force and small wear in the locations of the details.
With the increasing performance of the performance and revolutions of the engines, there was a need to create a car with new features. The lubricating fluids began to add additives that significantly improve technical specifications Lubricating products:
- reducing wear;
- antioxidative;
- antipid;
- contamilated;
- washing.
Modern engine oil for 4-stroke engines contains additives in the amount of 25% of the total volume. For such liquids, increased demands on the level of ash content and soot are not imposed.
The harmful refill 2-stroke motor 4-clock oil
Motor oil for four-stroke engines is not recommended for two-stroke power units. When combustion, the mixture is formed by ash, which forms a precipitate in combustion chambers and pistons.
In combination with lubrication, the residues of combustion turn into an abrasive powder. Acute abrasives apply irreparable harm mirror surfaces Cylinders, significantly reducing their service life.
Says are very harmful to work piston rings. It is clogged into the grooves, as a result, the rings lose mobility, the engine power decreases sharply. Save deposits also accumulate in the exhaust system, narrowing the lumen in the pipe, which makes it difficult to exhaust the exhaust gases and additional power losses.
Cartoon ash and soot deposits on pistons and cylinders cause detonation. The operational resource of the power unit is sharply reduced. The focusing of electrodes and spark plugs leads to their closure and blocking of the engine.
Varieties of four-stroke motor oils
The most popular among users is the engine oil for the four-stroke power unit, which meets the specifications of Jasama-2, Apisn. Domestic oils issued in accordance with GOST 17479.1-85 are adapted to the requirements of the SAE system.
Like all lubricants, engine oil for 4 clock engine has the following varieties:
- Synthetic motor oil. It does not forms Nagarov, has many positive characteristics. It is used in extreme trips.
- Semi-synthetic and mineral high-quality lubricants have durability, lack of smoke when combustion, maintain purity in the engine. It is recommended to fill for everyday use.
- Special semi-synthetic. Such types of lubricant are used when working on low grade fuel. Thanks to incoming additives, this oil It is characterized by excellent detergent properties, low consumption of avgar, preservation of useful qualities over the entire period.
Correct choice of 4 clock engine oil
For ordinary consumers, the most defining factors when choosing a suitable brand are viscosity. motor lubricant and its quality.
By viscosity lubricant Selected based on SAE tables in three criteria:
- lubricant used in engines in summer, SAE 20, 30, 40;
- winter materials from SAE 0W to SAE 25W;
- all-season automobile oils.
In addition to the basic basis, all-season contain special additives. They dilute the lubricant to speed up the engine launch in winter cold. At the same time, with their help, all working elements of the engine are reliably protected from harmful oxidative processes and large friction forces.
Designation of all-season motor oils by SAE: 10W30, 14W40, etc. The numerical designation that is standing in front indicates the lowest air temperature at which this oil does not start thickening. The latest numbers are the maximum allowable temperature. ambient For normal smooth operation of the motor in the summer heat.
Selection of quality oil in accordance with the API specification
The level of quality of engine oil on this system is denoted by two Latin letters. The first one speaks about the product belonging to the group of materials intended for gasoline or diesel engines - S and C, respectively. The second letter is directly the level of product quality. SL, SJ, SH brand oils are very popular. While the classes are SM, SE, SF, SG are extremely rare.
When producing motorcycles, manufacturers indicate the types of automotive recommended for use in a particular vehicle. This information is placed on the branded stickers and on the fuel plugs of the engines.
The use of a higher class lubricant is inappropriate. However, if the operating conditions are characterized by increased complexity, it is recommended to use machine oil with an increased viscosity index.
Air-cooled engines lubrication
For motors equipped with air-oil cooling system, this is especially true, because in the running engine temperature exceeds 100 ° C.
IN vehicleshaving worn four-stroke motors are also recommended to use more viscous lubricants to reduce losses.
Which oil to use in old 4 clock engines
Motors of older samples are suitable for all lubricating fluids of modern brands. The main thing is to remember, synthetics is characterized by greater fluidity compared to mineral counterparts.
The trading network also has a large assortment of both mineral and semi-synthetic engine oils.
