Features of engine oil for four-stroke internal combustion engines. Oil for 4-stroke air-cooled engines Neva oil for 4-stroke engines

Oil for 4 stroke engines has a number of differences from analogs designed for two-stroke motors. In the case of a two-stroke engine, lubrication is carried out with oil, which is previously dissolved in gasoline and, as a result, burns with it. In a four-stroke engine, on the other hand, everything is done to prevent oil from entering the combustion chamber.

Four-stroke motorcycle engine

Thus, the oil in a four-stroke engine should provide stable lubricating properties for as long as possible.

Accordingly, the content of various additives in modern motor oils for four-stroke engines is significantly higher and sometimes reaches 25%. Given the absence of special requirements for motor oils for four-stroke engines, ash content is not taken into account when selecting additives. As a rule, it can reach 2% or more. In addition, such lubricants differ more high level smokiness.

The principle of operation of a four- and two-stroke motor

Before considering the main differences between lubricants for 4-stroke engines, it is necessary to find out how such engines differ from two-stroke ones. One of the elements of a four-stroke engine is oil sump, constantly maintaining the required level of lubricant. From the crankcase, the lubricant is transferred by an oil pump to the lubrication system and ends up on the cylinder walls. The result is the friction of the piston against the wall not "dry", but in the form of sliding on the oil film.

To prevent oil from entering the combustion chamber, it is cut back into the oil bath by special oil scraper rings... In the case of four-stroke engines, the power of which does not exceed 5 l / s, the oil pump is most often absent. The distribution of oil in them is carried out by the oil mist created by the rotating crankshaft.

The loads in such engines are much less, therefore, the oil supply is provided regularly in the required quantities, which has a positive effect on the durability of the engine.

After one pouring of grease into the crankcase, it needs to be changed only once during the season. In this case, it is also necessary to control its level, although the car oil will not disappear anywhere. Besides, modern engines equipped with sensors capable of reminding of changes in the level of the oil substance.

How the 4-stroke engine works

The lubrication system in two-stroke motors works differently. In engines up to 30 hp it is necessary to prepare a mixture of gasoline and oil in a ratio of 50: 1. In this case, it is not necessary to shake the container after filling with gasoline and lubricant, since modern car oils are self-mixing. Even so, sometimes there is a lack of oil for high-quality lubrication of the cylinder bore. As a result, the engine starts to run "dry", which causes a corresponding decrease in its resource.

In motors, the power of which exceeds 40 hp, there is a tank for car oil, in which there is automatic preparation mixtures in the right proportions. The mixture of oil, air and gasoline first enters the cylinders and burns. At the same time, its combustion is not so effective, since the contained in fuel mixture the lubrication causes a decrease in the energy released. In addition, efficiency is reduced by the temporary opening of the cylinder outlet and inlet ports, resulting in partial loss of unburned mixture and its release into the atmosphere or water.

Differences between oils

So, consider what oil is for two-stroke engines differs from 4-stroke. As already mentioned, the main fundamental difference between the two types of engines is that two-stroke engines are lubricated with a lubricant that is previously dissolved in gasoline and burns out together with it. In a number of two-stroke engines, there is a separate system for supplying lubricant to the crankcase, but the essence does not change from this - the lubricant also burns out at the same time as gasoline.

In the case of four-stroke engines, measures are taken to prevent oil from entering the combustion chambers.

Accordingly, the basic requirements for motor oils also differ:

• in a two-stroke engine, the most complete combustion of the oil is required, which leaves a minimum carbon deposit in the form of ash and soot;
• Lubrication in a 4-stroke engine should provide stable lubrication characteristics for as long as possible.

Early in the age of engines internal combustion simple oil distillation was used to make lubricants. Such substances were used in both types of motors. This was due to the low specific power of the first auto engines, as well as low loads on the mating parts and the wear they caused.

However, subsequently, an increase in specific parameters and engine operating speed has led to the fact that such motor oils have exhausted their capabilities. As a way out of this situation, it was decided to use special additives in motor oils, called additives. They are able to significantly improve certain parameters of lubricants.

In auto lubricants, a whole range of such additives is usually used:
antiwear;

• washing;
• extreme pressure;
• antioxidant;
• anti-foam, etc.

As a result, today the content of additives in modern oils for engines with four strokes, it can be up to 25% of the total mixture volume. Considering that no special requirements are imposed on lubricants for such engines in terms of combustion efficiency, ash content can be ignored when selecting additives. Consequently, the ash content of such oils can exceed 2%, in addition, such motor oils can have a high smoke point.

Application of "4-stroke" oil in a 2-stroke engine

In the case of using a lubricant intended for 4-stroke engines in a two-stroke engine, the ash formed during the combustion of oil settles on the pistons and walls of the combustion chamber. In this case, combustion residues form an abrasive powder with the motor lubricant, which has an effect on the cylinder mirrors similar to real sandpaper. As a result, this abrasive literally cuts the parts, as a result of which their service life is significantly reduced.

Soot, which settles in the grooves, also causes serious damage. piston rings. As a result, the rings lose their mobility, which leads to a decrease in engine power. The soot deposited in the exhaust windows gradually reduces the size of their cross-section. This leads to a difficulty in exhausting the exhaust gases, that is, again, to a loss of power.

In addition, carbon deposits, including soot and ash, and deposited on cylinder heads and pistons, cause the development of such negative phenomena as glow ignition and detonation. It also causes a decrease in power and a decrease in the life of the motor. As a result of carbon deposits on the electrodes in the spark plugs, they may close and, accordingly, stop the engine.

Classification

At the moment, the most advanced oils for use in 4-stroke engines are oils that meet both JASO MA-2 and API SN (USA) specifications. Russian GOST 17479.1-85 has been adapted for SAE classification... It is recommended by car manufacturers to use motor oils for four-stroke engines with a viscosity class between 5W20 and 10W40.

Moreover, the higher the viscosity, the better the work will be. engine oil at elevated temperatures. This must be taken into account when selecting a lubricant in different climatic zones.

Like any other, motor oils for 4-stroke engines are divided into three types:

1. Synthetic, non-carbonating and with excellent protective properties. Can be used in extreme operating conditions.
2. High quality semi-synthetic and mineral motor oils are distinguished by good protection against wear, absence of smoke during combustion and maintenance of engine cleanliness. They are well suited for everyday driving.
3. Special semi-synthetic lubricants have detergent properties, low waste consumption, and high stability of characteristics. These lubricants can be used with low grade fuels.

How to choose 4 stroke oil

In many examinations of oils for four-stroke engines, foreign manufacturers are mainly represented by special motor oils, and domestic ones - by ordinary motor oils. At the same time, it is explained that a special 4-stroke oil for motorcycles differs from an automobile oil only in a lower amount of antifriction additives. At the same time, it is enough for an ordinary consumer to understand only two of the most important criteria that determine the merits of a certain brand: viscosity and quality.

The viscosity of motor lubricants for 4-stroke engines is classified in our country according to GOST 17479.1-85, which, as mentioned above, is adapted to SAE. According to this classification, three types of automotive oils are distinguished:

1. A group of car oils for engine operation only in the summer. Such lubricants are rarely commercially available, their marking: SAE 20, 30, 40. Lubricants with viscosity exceeding SAE 60 are not used in motors.
2. Technique with 4-stroke engines in winter period is practically not used, therefore we will give only the designation of such lubricants: SAE 0W, 5W, 10W and so on up to 25W.
3. All-season car oils are produced by adding special additives to base oil... These additives make the lubricant fluid enough to start the engine more easily at subzero temperatures. They also provide high protection for all working elements of the engine. All-season grades are designated by SAE as 10W40, 15W50, 10W60 and other numerical combinations that determine the range of use of the lubricant in accordance with the ambient temperature.

The number in front of the letter "W" indicates the negative temperature at which the car oil thickens, and the number after the letter indicates the maximum temperature at which the engine runs smoothly.

Engine oils for 4-stroke drives with air cooled differ from lubricants for water-cooled engines. Therefore, when selecting oils, it is necessary to take into account the marking, the composition of the fluids and the type of engines for which they are designed.

For 4-stroke air-cooled engines, high temperatures in the cylinder-piston group are characteristic. The oil does not mix with the fuel and does not enter the combustion chamber, therefore, the engine mixture for the specified type of drives must have the following properties:

1. The increased number of additives included in the motor fluid- up to 25% of the total.
2. Stability of viscosity characteristics at various temperature conditions. The lubricant should provide a quick and easy engine start, as well as instant oil flow to all rubbing drive elements.
3. Thermal oxidative stability. The structure of the mixture must be resistant to oxidation reactions, so that sediment and carbon deposits do not form, and the mixture does not become like water in structure.
4. Improved antiwear and extreme pressure characteristics to protect engine components from tribological loads.

You should not use motor oils developed for engines equipped with water cooling in 4-stroke air-cooled engines, these two types of oils contain a different composition of additives, the former are designed to heat the cylinder bore to a temperature of +160 0 С, and for the latter this parameter is - +220 0 C.

Standards

It is difficult for an ordinary buyer to understand the marking of lubricants, therefore, unscrupulous sellers often issue fluids for 2-stroke engines instead of 4-stroke ones. By purchasing such products, you reduce the drive life, so before going to the auto shop, read the generally accepted standards indicating that engine oil is suitable for air-cooled four-stroke drives:

1. The operating class according to the API system must comply with the requirements of SF / CC, not lower.
2. According to GOST, motor oil for these drives corresponds to group G.
3. SAE requires the fluid to meet the requirements of the vehicle dealer. This information can be found in the service book or on the filler cap. For air-cooled engines, it is recommended to fill with oil marked SAE 30 - summer class engine mixtures, the specified lubricant is thick enough so that it does not quickly liquefy at high operating temperatures.

Choosing a base car oil base for engines with air system cooling consider:

1. Mineral water - reduces friction force, reduces wear of drive elements, burning does not form carbon deposits and smoke, using it you can use leaded or unleaded gasoline.
2. Semi-synthetics - used with fuel of not very high quality, it is recommended for engines with a heavy load, ensures the stability of its structure during operation, but has increased fluidity, is applicable with leaded and unleaded gasoline.
3. Synthetics - prevents carbon formation, protects the engine from wear, is applicable only with unleaded fuel.

When choosing a lubricant, take into account the season when the vehicle will be used, summer types of oils begin to crystallize at temperatures below -10 0 C, winter ones withstand -25 0 C, all-season ones provide engine protection at any time of the year. See SAE classification for their operating temperature range.

The quality product can indicates that the lubricant is suitable for air-cooled 4-stroke drives. Correctly selected fluids must meet the requirements of the vehicle dealer to ensure proper engine operation. Preference should be given to the product famous brands, for which the sellers have a quality certificate. An incorrectly selected engine oil will lead to an increase in carbon formation, increased fuel consumption, and quick engine breakdown.

When choosing a specific brand of oil, please note that motorcycle oils differ in the quantitative composition of antifriction additives. This is due to the operating mode of the power units, snowmobiles, for example, are designed for extreme load modes, and scooters are used under much better operating conditions. The lubricants for these types of equipment will have a different composition and additives.

The need for the production of oils for air-cooled engines is caused by the appearance on the domestic market in last years a large number of equipment driven by this class of engines. The operating conditions of air-cooled engines differ from water-cooled engines primarily by the higher temperature regime of the cylinder-piston group.

In addition, when the engine is paired with an electric generator lubricating oil it is necessary to ensure quick and easy engine start and instant delivery through the lubrication system to all rubbing parts. These and other circumstances impose particularities on the quality requirements for oils for air-cooled engines.

• 4TD series oils are specially designed for use in 4-stroke gasoline and diesel engines air cooling of small equipment. They are formulated on the basis of highly refined mineral and synthetic polyalphaolefin oils, special additive packages that provide protection against the formation of deposits on the piston and in the engine crankcase, ring coking, and reduce energy consumption. The oils have high thermal and oxidative stability. To improve lubricating properties, oils contain extreme pressure additives protecting engine parts from wear under extreme loads and high temperatures Oh
• 4ТD Standard SAE 30 - mineral oil provides long-term and stable work motors over the entire load range. Recommended for use in summer, as well as in climatic zones with ambient temperatures ranging from -10 ° C to +40 ° C

Application

Recommended for use in the lubrication systems of four-stroke air-cooled gasoline and diesel engines, including those with moderate supercharging: garden tractors, lawn mowers, other garden equipment, snow plows, snowmobiles, small engines refrigerators and air conditioners, electric generators, motorcycles, boat motors and etc.

In two-stroke power units, the lubricant dissolves in the fuel, and then burns out simultaneously with it. Oil for four-stroke engines differs significantly from analogs used in two-stroke engines. It is of higher quality and retains the effect of its beneficial properties for a long time.

It contains a large number of special additives (at least 25%). Unlike other brands, there are no increased requirements for this oil in terms of ash content and smokiness. Their level reaches higher levels (ash content - more than 2%).

Features of the lubrication system of a two- and four-stroke engine

Many consumers are wondering what is the difference between 4-stroke and 2-stroke engines. A preset amount of lubricant is constantly maintained in the crankcase of a four-stroke power unit. From there, it is fed into the lubrication system by an oil pump.

As a result, an oil film forms on the pistons. In this case, there is no friction when it slides along the cylinder walls. In order to prevent penetration, oil liquid into the combustion chamber, oil scraper rings are installed, cutting off grease drips, directing them back to the crankcase.

The lubrication system for two-stroke engines is based on mixing fuel with engine lubricant in a 50/1 ratio. Modern automotive oils possess unique property self mixing. With a lack of substance for full lubrication of the working surfaces of the cylinders power unit works "dry". At the same time, the total engine resource is sharply reduced.

More powerful two-stroke motors over 40 hp. with. equipped with a special tank for automotive oil. It automatically dispenses and mixes the mixture in the correct proportions.

The disadvantage of 2-stroke lubrication systems is a decrease in combustion efficiency due to the content of oil particles in gasoline. Opening the intake and exhaust valves also negatively affects the performance of the powertrain. At the same time, there is a large release of unburned mixtures into the environment.

Differences between 2 and 4-stroke oils

Due to the structural differences in the lubrication systems of these engines, the requirements for lubricants are significantly different:

1. For two-stroke engines necessary condition is the ability of the most complete combustion of oil. This produces a minimum amount of carbon deposits (soot and ash).
2. In four-stroke engines, the main requirement for engine oil is the long-term provision of lubricating effects due to the preservation of the useful properties of the material used.

Earlier in production lubricants the method of simple oil distillation was used. The resulting product was suitable for the lubrication of parts and assemblies, engines of any kind. Them specifications satisfied the requirements of motors with low power, low friction force and low wear at the mating points of the parts.

With the growth of performance indicators and engine speed, it became necessary to create motor oils with new capabilities. Additives have begun to be added to lubricants that significantly improve technical specifications lubricating products:

• reducing wear;
• antioxidant;
• anti-foam;
• extreme pressure;
• washing.

Modern motor oil for 4-stroke engines contains additives in the amount of 25% of the total volume. For such fluids, there are no increased requirements for the level of ash and soot.

Why refueling a 2-stroke engine with 4-stroke oil is harmful

Engine oil for four-stroke engines is not recommended for two-stroke power units. When the mixture burns, ash is formed, which forms a sludge in the combustion chambers and pistons.

In combination with the lubricant, combustion residues are converted into an abrasive powder. Sharp abrasives cause irreparable damage to the mirror surfaces of the cylinders, significantly reducing their service life.

Soot is very harmful to piston ring performance. It clogs into the grooves, as a result, the rings lose their mobility, and the engine power drops sharply. Soot deposits also accumulate in the exhaust system, narrowing the pipe clearance, which makes it difficult for exhaust gases to escape and additional power losses.

Ash and soot deposits on pistons and cylinders cause detonation. At the same time, the service life of the power unit is sharply reduced. Coking of electrodes and spark plugs leads to their closure and blocking of engine operation.

Varieties of four-stroke engine oils

The most popular among users is an engine oil for a four-stroke power unit that meets JASOMA-2, APISN specifications. Domestic oils issued in accordance with GOST 17479.1-85 are adapted to the requirements of the SAE system.

Like all lubricants, 4-stroke engine oil has the following varieties:

1. Synthetic engine oil. It does not form deposits and has many positive characteristics. It is used for extreme trips.
2. Semi-synthetics and high-quality mineral lubricants are wear-resistant, smoke-free during combustion, and maintain cleanliness in the engine. Recommended for everyday use.
3. Special semi-synthetics. These types of lubricants are used when operating on low-grade fuels. Due to the included additives, this oil it is characterized by excellent detergent properties, low waste consumption, preservation of useful qualities for a long period.

Choosing the right 4-stroke engine oil

For ordinary consumers, the most decisive factors in choosing the right brand are the viscosity of a motor lubricant and its quality.

In terms of viscosity, a lubricant product is selected based on the CAE tables according to three criteria:

• summer lubricant, SAE 20, 30, 40;
• winter materials from SAE 0W to SAE 25W;
• all-season car oils.

In addition to the basic base, all-seasons contain special additives. They thin the lubricant to speed up engine starting in winter cold. At the same time, with their help, all working elements of the engine are reliably protected from harmful oxidative processes and high friction forces.

SAE designation for multigrade engine oils: 10W30, 14W40, etc. The numeric designation in front indicates the lowest air temperature at which this oil has not yet begun to thicken. The last figures are the maximum permissible ambient temperature for normal smooth operation of the motor in the summer heat.

Oil selection by quality in accordance with API specification

The quality level of engine oil according to this system is indicated by two Latin letters. The first indicates that the product belongs to a group of materials intended for gasoline or diesel engines- S and C, respectively. The second letter is directly the level of product quality. Oils of the SL, SJ, SH brands are very popular. While the classes SM, SE, SF, SG are used extremely rarely.

When producing motorcycles, manufacturers indicate the types of motor oils recommended for use in a particular vehicle. This information placed on brand stickers and engine filler plugs.

Usage lubricating fluid a higher grade is impractical. However, if the operating conditions are more difficult, it is recommended to use a machine oil with a higher viscosity index.

Air Cooled Engine Lubricant

For motors equipped with an air-oil cooling system, this is especially important, since the temperature in a running engine exceeds 100 ° C.

IN vehicles with worn out four-stroke motors, it is also recommended to use more viscous lubricants to reduce losses.

What oil to use in old 4-stroke engines

All modern brands of lubricants are suitable for older engines. The main thing to remember is that synthetics are characterized by greater fluidity compared to mineral analogues.

The trading network also has a large assortment of both mineral and semi-synthetic engine oils.

Air-cooled four-stroke engines require lubricants. Moreover, such that the quality meets the requirements, which we will talk about.

Owners of equipment prefer to use oil marked Sae, which must be filled into the engine at an air temperature of at least 5 ° C. It contains a multifunctional additive package with anti-wear and anti-corrosion properties.

This fluid well protects the rubbing parts of the engine from wear and overheating, ensures its cleanliness and increases the service life. Sae lubricants are manufactured with different types fundamentals, which affects their market value.

So, the price of synthetics for a package of a liter container varies from 240 to 290 rubles, mineral - from 350 to 510 rubles.

Oil "Scout-5L" also has exceptional lubricating characteristics, which has won a high reputation among domestic owners of motoblocks and can be called a full-fledged analogue of Sae 30. It is comparable in quality, but more affordable, which makes this product even more in demand. Such oil in a 5-liter container costs 1390 rubles, which in terms of 1 liter is only 278 rubles.

What is the difference between two-stroke oil and four-stroke

Some types of engine oil are designed for four-stroke powertrains, while others are for two-stroke. They are not interchangeable, and they should be poured in accordance with the intended purpose, because different requirements are imposed on lubricants for motors with different duty cycles. So, oil for four-stroke engines, where it is used forced system lubrication, is designed for long-term exposure and is designed to provide a more stable coating of parts. In 2-stroke engines, the oil comes along with the fuel and should instantly dissolve in it, burning smokelessly with a minimum of deposits in the form of soot and ash. Therefore, a characteristic feature of 2-stroke oils is their good purification and a minimum content of aggressive additives. They, unlike a 4-stroke fluid, do not contain ash, EP and anti-wear additives, which allows them to almost completely burn together with the fuel without the formation of carbon deposits and exhaust toxicity.

A feature of oils for four-stroke engines is the content of many organometallic additives, which are aimed at improving their physical and mechanical properties and increasing the efficiency of action. And if you pour such a mixture into an engine with a working cycle of two strokes, it will lead to the formation of ash deposits on the surface of the piston and the walls of the combustion chamber. The increased accumulation of deposits, in turn, can provoke the appearance of various troubles, which can be eliminated only by doing a complex and expensive repair of the motor-block motor. A lot of harm is done by soot, which clogs air filter and settles in the piston ring grooves if an inappropriate petroleum product is used. The accumulation of soot is fraught with the loss of mobility of the rings, and this is a direct way to reduce the engine power of the walk-behind tractor, deteriorate its operation and even complete failure.

Classification of engine oils

Most important parameters engine oil viscosity grade and temperature Range at which it can be used. In the marking, the number in front of the letter "W" indicates the temperature at which the liquid thickens. The number after the letter indicates the maximum temperature at which it ensures uninterrupted operation of the engine. These indicators must correspond to those indicated in the operating instructions for the garden walk-behind tractor. It should also be borne in mind that high-viscosity lubricants, such as Sae 30, Sae 40, are designed for the use of equipment in the summer, and low-viscosity, for example, 5W30, for its winter operation. A low-viscosity oil product will quickly evaporate at high temperatures and will not be able to provide full lubrication of mechanisms. Too thick liquid will become an obstacle to starting the engine at low air temperatures.

The chemical composition of the base of the lubricant is also important, as it affects the properties of the product and determines its effect.

Mineral engine oil:

• provides a decrease in friction force;
• reduces the formation of sludge and carbon deposits;
• reduces wear of working parts;
• does not form harmful exhaust gases and does not pollute the air.

Synthetics contain additives that prevent carbon formation and protect the power unit from wear. Semi-synthetics are produced by mixing mineral and synthetic bases with the use of special additives.

Benefits of synthetic and semi-synthetic motor fluid:

• increased fluidity;
• low volatility;
• low consumption for waste.

For 4-stroke motors of walk-behind tractors, cultivators and other garden equipment, oil products with the Sae-30 marking, which have a high viscosity and are intended for summer use, are excellent. They can be produced on a mineral or synthetic base and contain various additives. A fluid with such markings reliably protects rubbing surfaces from corrosion and rapid wear, prolongs the life of the engine.

An analogue of the summer Sae-30 can be any multigrade oil, in the designation of which the second number is "30". For example, a liquid labeled "5W-30" has similar characteristics when used in summer, but it can also be poured into winter time when the air temperature is not lower than -35 o C. Grease "10W-30" also has properties similar to Cae 30 when used in the warm season, but its operating range is limited to a temperature of -25 o C.

The most popular Sae 30 summer oils and multigrade oils are described below.

This grade of grease is all-weather and can be used in a wide temperature range - from -25 o C to +40 o C without reducing its properties.

Choosing the best oil for a walk-behind tractor and cultivator

Having a cultivator with a Chinese, American engine or a walk-behind tractor with a Honda engine, you need to remember that the duration of the operation of the motor unit is influenced not only by the timeliness of troubleshooting, but also by the quality of the oil used, as well as the regularity of its replacement. An incorrectly selected mixture or improper lubrication of parts in friction zones leads to increased carbon formation, an increase in fuel consumption and a quick engine breakdown.

Lubricants for 4-stroke engines of motor vehicles are produced in a fairly wide range - from budget to more expensive ones. To choose the right product, you need to navigate the labeling and parameters that indicate its main criteria. So, the marking "S" classifies a group of lubricants provided for gasoline engines, and the letter "C" - for diesel.

All the requirements for motor lubricants for motor-blocks Neva, Scout, Crosser, Salyut, Zubr, Favorite, Dobrynya and other models equipped with a four-stroke air-cooled engine are also met by a number of automotive lubricants... To the question: "Is it possible to fill car oil into the walk-behind tractor? " experts answer - “Yes, only when using different grades of liquid, different consumption rates and the degree of carbon deposits can be observed”. But they do not recommend pouring transmission fluid into the motor-block motor, explaining this by the fact that this type of substance is not intended to work in the range of high speeds and high temperatures. If the transmission is poured into the engine, then it will begin to burn intensively, precipitate, clog the ducts and the air filter, which can lead to serious damage.

How much do you need to fill?

Cultivators, mini tractors and walk-behind tractors supplied to Russian market are mainly equipped with Subaru, Briggs & Stratton, Honda or their Chinese counterparts... They may be different power and accommodate different amounts of grease. How do you know how much lubricant to pour from the canister so that the 4-stroke engine works at its optimum level and its parts are not erased from lack of lubrication?

The consumption rates of lubricants can be found in the operating instructions or technical documentation attached to the motorcycle.

The table below shows the individual lubrication rates for the most popular engine models.

Flood motor lubricant you can simply determine its amount by the dipstick on the plug. The minimum level is practically limited by the length of the dipstick itself, and the maximum level reaches the drain thread. You can also navigate by looking through the crankcase hole.

As a rule, about 0.6 liters of liquid is placed in a walk-behind tractor with a 6-8-strong engine, a little more than 1 liter in more powerful units. It is not for nothing that the most popular packaging among manufacturers is a volume of 0.6 liters. It is this rate of oil that is enough to fill up to the full level motor vehicles of medium power, which are in greatest demand among owners of garden and summer cottages.

Prices

High-quality four-stroke oils for motoblocks are produced by companies different countries, including Russia, France, Germany, Sweden, USA. A large price range and a variety of products allows you to choose the most the best option for any unit of small-sized agricultural machinery.

The table shows the average prices for the most popular lubricants for 4-stroke internal combustion engines.

In order for a walk-behind tractor or cultivator to be durable and to perform their functions efficiently, it is necessary to create optimal conditions for the engine's operation: to fix problems in a timely manner, to lubricate the rubbing surfaces. It is important that only suitable engine oil is used to lubricate parts in friction zones, which should be purchased based on technical requirements the power plant and the real conditions of its operation.
