Oil for motor-pump 4 x stroke. Oil for four-stroke engines with air-cooled. Fourth: how does the engine run

Four-stroke engines S. air cooled We need lubricants. With such such that the quality corresponds to the requirements of which we will tell.

The owners of the technique prefer to use SAE marking oil, which must be poured into the engine at an air temperature not less than 5 o C. It includes a multifunctional package of additives with anti-wear and anti-corrosion characteristics.

This liquid protects well from wear and overheating driving engine parts, ensures its cleanliness and increases the resource of the work. SAE standard lubricants are manufactured with different type Basics, which affects their market value.

So, the price of synthetics per packaging of liter container varies from 240 to 290 rubles., Mineral - from 350 to 510 rubles.

Skout-5l oil has exceptional lubricating characteristics, which won a high reputation from domestic owners of motoblocks and can be called a full-fledged analogue of SAE 30. It is comparable to it in quality, but more accessible by price, which makes this product Even more sought after. Such an oil in a 5 liter container costs 1390 rubles, which in terms of 1 liter is only 278 rubles.

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

Some types of engine oil are designed for four-stroke power units, while others - for two-strokes. They are not interchangeable, and they should be poured in accordance with the appointment, because various requirements are imposed on lubricants for motors with different working cycle. So, oil for four clock engineswhere used forced system Lubrication is designed for a long impact and is designed to provide a more stable coating of parts. In 2-stroke engines - the oil comes together with the fuel and should be dissolved instantly in it, smuggling with a minimum of sediments in the form of soot and ash. Therefore, a characteristic feature of 2 clock oils is good cleaning and minimal content of aggressive additives. They, in contrast to the 4-stroke fluid, do not accommodate the ash, antisaded and anti-emission additives, which allows them to almost completely burn with fuel without the formation of a nagar and exhaust toxicity.

A feature of oils for four-stroke engines is the content of many organometallic additives, which are aimed at improving their physicomechanical properties and an increase in the efficiency of action. And if you pour such a mixture into the engine with a working cycle into two clocks, this will result in the formation of ash sediments on the surface of the piston and the walls of the combustion chamber. Increased accumulation of deposits, in turn, can provoke the emergence of various troubles, eliminate which is possible only having done the complex and expensive repair of the motorcycle motor. Many harm causes a soot that litters air filter and settles in grooves piston ringsIf using the inappropriate petroleum product. Say accumulation is fraught with the loss of mobility of the rings, and this is a direct path to reducing the engine power of the motor-block, deterioration of its work and even complete failure.

Classification of motor oils

Most important parameters Motor oil are the degree of viscosity and temperature Rangewhere it can be used. In the marking, the number in front of the letter "W" indicates the temperature in which the liquid thickens. The digit after the letter denotes the maximum temperature at which it provides uninterrupted engine operation. These indicators must comply with what are indicated in the instruction manual for gardening motor-block. It should also be borne in mind that highly viscous lubricants, such as SAE 30, SAE 40, are intended for the use of technology in the summer, and low-viscosity, for example, 5W30 - for its winter operation. Lumpy petroleum products high temperatures It will quickly evaporate and will not be able to ensure full-fledged lubrication of the mechanisms. Too thick liquid will become an obstacle in the launch of the motor at low air temperatures.

The chemical composition of the lubricant base is also important, since it affects the properties of the product and causes its impact.

Mineral motor oil:

• provides a decrease in the friction force;
• reduces the formation of precipitation and nagar;
• reduces wear of working parts;
• does not forms harmful exhausts and does not pollute the air environment.

Synthetics accommodates additives that prevent ingorage and protecting the power unit from wear. The semi-synthetic is made by mixing the mineral and synthetic bases using special additives.

Advantages of synthetic and semi-synthetic engine fluid:

• increased fluidity;
• low evaporation;
• small consumption on the avgar.

For 4-stroke motor motoblocks, cultivators and other garden equipment, oil products with SAE-30 marking, having a high viscosity and designed for summer use are excellent. They can be produced on a mineral or synthetic basis and accommodate various additives. The liquid with such marking reliably protects the rubbing surfaces from corrosion and rapid wear, extends the service life of the engine.

Analogue of summer SAE-30 can perform any all-season oilIn the designation of which the second digit is "30". For example, the liquid with the labeling "5W-30" has similar characteristics when used in summer, but it can also be pouring into winter timewhen the air temperature is not lower than -35 o C. Lubricant "10W-30" also has similar SAE 30 properties when used in warm season, but its operating range is limited to the temperature -25 o C.

The most popular grades of summer oils with marking SAE 30 are described below, as well as intended for all-season use.

Such a grease variety is all-season and can be used in a wide range of temperatures - from -25 ° C to +40 ° C without reducing its properties.

Choose the best oil for the motoblock and cultivator

Having a cultivator with a Chinese, American engine or a motor-block with a Honda engine, it must be remembered that the duration of the moto unit does not only affect the timeliness of troubleshooting, but also the quality of the oil used, as well as the systematic replacement. Incorrectly selected mixture or not on time, the lubrication of parts in the friction zones leads to increased nagara formation, increasing the flow rate of fuel and fastest motor failure.

Lubricants for 4-stroke engines motorcycles are available in a fairly wide range - from budget to more expensive. To select the appropriate product, you need to navigate in the labeling and parameters denoting its main criteria. Thus, the labeling "S" is classified a group of lubricants provided for gasoline engines, and the letter "C" - for diesel.

All requirements for motor lubricants for Motoblocks Neva, Scout, Crosser, Salute, Bison, Favorite, Dobrynya and other models equipped with a four-stroke air-cooled engine, is also responsible car lubricants. To the question: "Is it possible to pour automobile oil in a motor-block?" Specialists respond - "Yes, only when using different varieties of liquids, various costs of consumption and the degree of formed by Nagara can be observed. But pour into the motor motoblock transmission fluid they do not recommend explaining this by the fact that this type Substances are not designed to work in the range of large revolutions and high temperatures. If there is a transmission to the motor, it will start intensely burn, fall into the precipitate, score channels and air filter, which can lead to serious breakdowns.

How much do you need to pour?

Cultivators, minitractors and motoblocks supplied to the Russian market are mostly equipped with SUBARU, Briggs & Stratton, Honda or their power plants chinese analogues. They can be different power And accommodate a different amount of lubrication. How to find out how much lubricant liquid is pouring out of the canister so that the 4-stroke engine worked in optimal mode and its details were not erased from the lack of lubrication?

Consumption rate of lubricants can be found from the instruction manual or technical documentationattached to motorcycles.

The table below shows individual lubrication consumption norms for the most popular models of engines.

You can simply pour the motor lubricant by defining its number on the punch on the plug. The minimum level is practically limited to the length of the probe itself, and the maximum - comes to the thread of the drain hole. You can also navigate, looking into the crankcase hole.

As a rule, about 0.6 liters of liquid is placed in a motoblock with a 6-8-power engine, in more powerful units - a little more than 1 liter. The most popular packaging of manufacturers is a volume of 0.6 liters. It is such a norm of oil that is enough to refuel the medium power to the full level, which uses the greatest demand among the owners of garden and country sites.

Prices

High-quality four-stroke oils for motoblocks produce companies different countries, including Russia, France, Germany, Sweden, USA. Large price range and variety of products allows you to choose the most optimal option For any unit of small agricultural machinery.

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

In order for the motor-block or cultivator to be durable and qualitatively performed its functions, it is necessary to create optimal conditions for the engine operation: timely troubleshooting, make lubrication of rubbing surfaces. It is important that only suitable engine oil was used to lubricate parts in the friction zones, to acquire which follows from the technical requirements of the power plant and the real conditions for its operation.

Where can one buy?

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 effect. 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 penetration, oil fluid In the combustion chamber, the rings are placed oil-cutting, cutting 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 possess a unique feature blending 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 are more than 40 liters. from. Equipped with a special tank for automotive 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. The opening of intake and exhaust valves also negatively affects the performance of the power unit. 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:

1. For two-stroke engines 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.
2. 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. IN 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 cause irreparable harm to the mirror surfaces of 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, adapted to the requirements of the SAE system.

Like all lubricants, engine oil for 4 clock engine has the following varieties:

1. Synthetic motor oil. It does not forms Nagarov, has a multitude of positive characteristics. It is used in extreme trips.
2. 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.
3. Special semi-synthetic. Such types of lubricant are used when working on low grade fuel. Thanks to incoming additives, this oil is characterized by excellent detergent properties, a small consumption of a voligator, preserving 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 the viscosity of motor lubrication and its quality.

By viscosity, the lubricant is selected based on SAE tables by 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 ambient temperature for normal uninterrupted 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 Placed on branded stickers and on the filler tubes of engines.

The use of a higher class lubricant is inappropriate. However, if 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.

The need to produce oils for air-cooled engines is caused by the appearance on the domestic market in last years A large number of equipment with a drive from such a class of engines. The operating conditions of air cooling engines differs from water cooling engines primarily by a higher temperature regime of the cylinder-piston group.

In addition, when the engine is in a pair with an electric generator lubricant Oil It is necessary to provide quick and easy engine start and instant delivery by lubrication system to all rubbing items. These and other circumstances impose features on the quality requirements for air-cooled engines.

• 4TD series oils - specially designed for use in 4-stroke gasoline and diesel engines Air cooling of small equipment. Prepared on the basis of highly purified mineral and synthetic polyalphaole oils, special packages of additives that protect against the formation of deposits on the piston and in the engine crankcase, the rings, reduce energy consumption.

Application

Recommended for use in the lubrication systems of four-stroke engines of air cooling of gasoline and diesel, including moderate superimposure: garden tractors, lawn mowers, other garden machinery, snowproofs, snowmobiles, small engines refrigerators and air conditioners, electric generators, motorcycles, boat engines and etc.

Oil for 4-stroke engines has a number of differences from analogs intended for two-stroke motors. In the case of a two-stroke engine, oil lubrication is made, which is pre-dissolved in gasoline and, as a result, burns with it. In the engine four-stroke, on the contrary, everything is done so that the oil does not penetrate the combustion chamber.

Four-stroke motorcycle engine

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

Accordingly, the content of various additives in modern engine oils for four-stroke engines is significantly higher and sometimes reaches 25%. Considering the lack of special requirements for car accidents for four-stroke engines, as a selection of additives is not taken into account ash content. As a rule, it can reach 2% or more. In addition, such lubricants are different high levels Smoke.

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

Before considering the main differences between lubricants for 4-stroke engines, it is necessary to find out what the motors are different from the two-strokes. One of the elements of the four-stroke motor is oil Carter, on an ongoing basis, supporting the required lubricant level. From the crankcase, the lubricant with an oily pump is transmitted to the lubricant system and is on the walls of the cylinder. The result is the friction of the piston about the wall is not "dry", but in the form of sliding over the oil film.

In order for the oil to penetrate the combustion chamber, it is cut back into the oil bath special masonry 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 oil distribution in them is carried out at the expense of the oil mist generated by the rotating crankshaft.

Loads in such engines are much smaller, so oil flow is provided regularly in the required amounts, which has a positive effect on the durability of the motor.

After one pouring lubricant in the crankcase, it is required only once during the season. At the same time, it is also necessary to control its level, although the car will not disappear anywhere. Moreover, modern engines Equipped with sensors capable of reminding changes in the oil substance levels.

Principle of operation of the 4-stroke engine

The lubrication system in two-stroke motor acts otherwise. In engines up to 30 hp Preparation of a mixture of gasoline with oil in a 50: 1 ratio is necessary. At the same time, it is not necessary to shake the container after filling with gasoline and lubricant, since modern autosals are self-drying. Even despite this, sometimes there is a shortage of oil for high-quality lubrication of the cylinder mirror. As a result, the engine begins to work "dry", which causes a corresponding reduction in its resource.

In motors, the power of which exceeds 40 hp, there is a tank for a car in which automatic preparation Mixes in the right proportions. A mixture of oil, air and gasoline first enters the cylinders and burns. In this case, its combustion is not so effective because the contained in fuel mixes Lubrication causes a decrease in the energies. In addition, efficiency is reduced due to the temporary discovery of the graduation and intake windows of the cylinder, the result of which is a partial loss of a unburned mixture and emissions to the atmosphere or water.

Differences of oils

So, consider than the oil for two-stroke engines differs from 4-strokes. As already mentioned, the main fundamental difference between the two types of engines is that the two-stroke motors are lubricated lubricantdissolved in gasoline and with it as a result of burning. In a number of two-stroke engines, there is a separate system for supplying a lubricant to the crankcase, but the point of this does not change - the lubricant also burns simultaneously with gasoline.

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

Accordingly, the basic requirements for cars differ:

• in two-stroke engine It requires as complete combustion of the oil as possible, in which the minimum tag remains in the form of ash and soot;
• lubricant in the 4-stroke engine should provide stable lubricating characteristics as long as possible.

At the beginning of the era of internal combustion engines for the manufacture of lubricants, a simple distillation of oil was used. Such substances were used in both varieties of motors. It was associated with the small specific power of the first auto motors, as well as low loads on the interface of the parts and the wear, which they caused.

Nevertheless, subsequently the growth of the specific parameters and engine speeds led to the fact that such cars have exhausted their capabilities. As an exit of the current situation, it was decided to apply special additives in the car, called additives. They are able to significantly improve certain lubricant parameters.

In self-mixing, a whole range of such additives is usually applied:
anti-wear;

• detergent;
• contamilated;
• antioxidative;
• heavy etc

As a result, today's content of additives in modern oils For four-standing engines, it can be up to 25% of the total mixture. Considering that there are no special requirements for lubricants for such engines in terms of combustion, during the selection of additives, you can not take into account ash content. Consequently, the ash of such oils may exceed 2%, in addition, such autosals can have high smoke.

The use of "4-clutter" oil in a 2-stroke engine

In the case of use, the lubricant intended for 4-cycle engines in the two-stroke motor, which is formed during the combustion of the oily oil sends to the pistons and walls of the combustion chamber. At the same time, the residues of combustion form with a motor lubricant abrasive powder, which has an impact on the cylinder mirrors, similar to this emery paper. As a result, this abrasive literally saw details, as a result of which their life is significantly reduced.

Quite serious harm is also delisting the soot that settles in the grooves of piston rings. As a result, the rings lose mobility, which leads to a decrease in engine power. Soot, laid in exhaust windows, gradually reduces the size of their cross section. This leads to difficulty producing exhaust gases, that is, again, to loss of power.

In addition, the Nagar, which includes soot and ash, and laid on the heads of cylinders and pistons, causes the development of such negative phenomena as a cylinder ignition and detonation. It also causes a reduction in power and reduced motor resource. As a result of nagar deposits on the electrodes in the ignition candles, their closure may occur and, accordingly, stop the engine.

Classification

At the moment, the most advanced for use in 4-stroke engines are oils that are simultaneously the JASO MA-2 and API SN (USA) specifications. Russian GOST 17479.1-85 was adapted under sAE classification. Car manufacturers are recommended to use for four-stroke engines of an automated vehicle, which are viscosity, the class of which is in the range between 5W20 and 10W40.

At the same time, the viscosity is higher, the better the operation of the engine oil at elevated temperatures. This must be taken into account in the process of selecting lubrication in various climatic zones.

Similar to any other, motor vehicles for 4-stroke engines are divided into three varieties:

1. Synthetic, non-nagar and possessing excellent protective characteristics. Can be used in extreme operating conditions.
2. The semi-synthetic and mineral high-quality minerals are characterized by good protection against wear, lack of smoke in the combustion process and maintaining the purity of the engine. They are well suited for everyday driving.
3. Special semi-synthetic lubricants have detergent properties, a small value of the flow rate, as well as high characteristics stability. Such lubricants can be used when using low grade fuel.

How to choose 4 clock oil

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

Viscosity motor lubricants For 4-stroke engines is classified in our country according to GOST 17479.1-85, which is already mentioned above, adapted to SAE. According to this classification, three types of automotive oils differ:

1. A group of automotive for the engine operation only in the summer. Such lubricants rarely go on sale, their marking: SAE 20, 30, 40. Lubricants whose viscosity exceeds SAE 60, not used in motors.
2. Technique with 4-clock engines in winter It is practically not used, so we give only the designation of such lubricants: SAE 0W, 5W, 10W and so on to 25w.
3. Machines All-season are produced by adding special additives in basic oil. Such additives make lubrication sufficiently liquid for easier engine start at negative temperatures. They also provide high protection of all engine work items. All-season varieties are indicated by SAE as 10W40, 15W50, 10W60 and other numeric combinations that determine the range of use of lubricant in accordance with the ambient temperature.

The number located in front of the letter "w" indicates a negative temperature at which the car thickens, and the digit after the letter is the maximum temperature at which the engine is uninterrupted.

One of the main factors affecting the resource of the internal combustion engine 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 is needed 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.
• Stable composition of the package of antifriction and non-promotional additives Allows oil for a long time to maintain its properties with regular heating and cooling 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 air-cooled engines, since the oil falling into the piston rings zone 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).
• Purely summer options - SAE 30, SAE 40. It is necessary to carefully read the chalk of oils: a number of specialized oils for garden equipment with a viscosity of 5W30 are designed exclusively 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 special line of oils for garden equipment on a mineral base, in this case low cost in the opposite direction 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 motoblocks, and are associated with common automotive oils, the only difference can be its consumption and the amount of carpent formed during long-term operation in the air cooling engine.

For this reason, although this material also considers specialized lubricants, in the absence of the possibility of their acquisition you can always use the corresponding automotive engine oils described.

Classification of oils
