Automotive oil for walk-behind tractors with a garden equipment generator. Features of engine oil for four-stroke internal combustion engines

When purchasing a walk-behind tractor, it must be remembered that its durable operation depends not only on the replacement of consumables, parts, tightening the necessary nuts, but also on the timely replacement of oil in the walk-behind tractor.

The durability and performance of the equipment depends on how correctly you choose engine oil for walk-behind tractors. The question arises, what kind of oil to fill in the motor block engine, how to replace it or check the level.

1 Engine oil functions

With each technique, including walk-behind tractors, a passport and instructions are included with the sale. Manufacturers always recommend in the instructions those types of oil that will allow the equipment to last a long time and not break.

You need to know that during the operation of the walk-behind tractor, engine oil performs 4 functions at once:

• cooling;
• lubricant;
• cleaning;
• seal.

When the air-cooled walk-behind tractor engine is running, the lubricant burns and remains on the hot cylinder, after which a smoky exhaust is formed. The deposition of resinous substances drastically affects the contamination of some parts and difficult to lubricate.

Using a walk-behind tractor, it is necessary to choose a lubricant based on the climatic zone.

For example, when using grease type SAE 10W30 at a temperature of 5 ° C and above, its consumption will be much higher and there will be a high probability of engine breakdown. It is undesirable to pour summer lubricants at air temperatures below 5 ° C. Such use leads to difficult starting of the engine and damage to the cylinder mirror.

1.1 Classification of oil grades by viscosity

The viscosity grade of motor oils is usually classified according to the SAE (Society of Automotive Engineers).

High-quality flushing oil MPA - 2

Namely:

1. Summer varieties - oils belonging to this category are used in summer, have a high viscosity and without a letter designation. These include: SAE 20, 30, 40, 50, 60.
2. Winter grades - these oils are used in the winter and have a low viscosity. The letter designation of this variety is W (Winter). These include: SAE 0W, 5W, 10W, 15W, 20W, 25W.
3. All-season varieties are the most popular at present, as they are used both in summer and in winter. They are indicated by a double combination: 5W-30, 10W-40.

In addition to differences in lubricants based on seasonal characteristics, they are divided into two types:

• mineral;
• synthetic;
• semi-synthetic.

All oils are also divided into lubricants for both 2-stroke and 4-stroke engines. Usually, 4-stroke air-cooled engines are installed on walk-behind tractors. In such engines it is necessary to pour only 4-stroke oil.

An air-cooled engine heats up more during operation than a water-cooled engine under the same operating conditions. Therefore, the filling liquid must have low volatility and high thermal and oxidative stability. Also modern oils should be environmentally friendly, those. the amount of smoke and toxicity of exhaust gases is controlled.

Since the waste is often simply incinerated in boilers or steam generators, it must not contain components that form toxic compounds when burned. In a motor cultivator that runs on gasoline and does not have instructions, it is better to pour 4-stroke 5W30 or SAE30 brand oil.

In winter, winter or gear oil, such as 0W40, will be preferable. But you have to pay for such quality. It’s not worth saving on this, because high-quality oil affects less engine wear and its durability.

2 How to choose a walk-behind tractor: diesel or gasoline?

Diesel powered units are mainly designed to work on large plots of land. This type of engine is capable of producing high tractive effort due to operation at low speeds. They are designed for a much larger amount of resources than gasoline.

Therefore, their work can be carried out for much longer without stopping. Do not let the diesel engine run at idle often, because this leads to its breakdown. Sometimes it is necessary to load the unit at full capacity for 3-4 hours. This will extend the life of the walk-behind tractor.

The main advantages of a diesel walk-behind tractor:

1. Convenient maintenance and operation, as there are no candles and magnetos, and there is also no carburetor, which has to be constantly adjusted.
2. Maximum ground grip due to high weight.
3. Cooling is possible either with air or water. Gasoline engines lack this diversity.
4. The fuel consumption run can vary from 2 to 5 liters per 100 km, based on the power of the unit.
5. The operation of the engine is ensured by stable revolutions due to increased traction.

The price can scare away when buying a diesel walk-behind tractor. But it is worth considering that it consumes less fuel than gasoline, and diesel is cheaper than gasoline. This purchase will pay for itself over time.

2.1 Gasoline walk-behind tractors

Motoblocks of this class are ideal for cultivating small plots of land. In a gasoline engine, fuel is ignited by a spark generated by a spark plug. These motoblocks are very maneuverable and light.

For a gasoline engine, any gasoline used in modern cars will do. They can only work at high speeds. Repair and maintenance is much cheaper than diesel engines.

The main advantages of a gasoline engine:

1. It can be started in all weather conditions without an electric starter.
2. Reduced noise level.
3. Significantly less vibration when driving.

Main The advantage over the diesel engine is the relatively low cost. They are suitable for small areas (20-30 acres), as they do not withstand heavy loads. The diesel engine will be optimal in all other cases.

2.2 Changing the oil in the walk-behind tractor

There are many different opinions about how often you need to change the oil for walk-behind tractors. But in this case, you need to rely on the manufacturer's instructions. If there is no instruction, you can change the lubricant in a common way among users.

The first oil change in the walk-behind tractor is carried out after the unit has been run in. Running in the engine and all its components must be carried out at idle. Before starting the engine, you need to make sure that there is lubricating fluid in it. When buying a unit, its engine may be completely dry.

After an hour of engine operation, the first oil change is performed. The next replacement is after 5-6 hours of operation. It is recommended to change the oil in the walk-behind tractor every 40 hours of operation, which is much more often than in a car. After the winter period, a lubricant change is mandatory. It doesn’t matter how many hours the walk-behind tractor has worked, if its lubricant has become viscous, darkened, or it emits a strong smell of burning, then it needs to be changed.

Before changing the oil, it is necessary to warm up the walk-behind tractor. This is necessary in order for the lubricant to become more fluid. The walk-behind tractor is installed in a horizontal position. The drain plug is unscrewed and the old fluid is removed from the crankcase.

After that, it is required to screw back the drain tank plug and fill the lubricant through the filler neck. You can check the oil level being filled with a dipstick plug. The level must be between the Minimum and Maximum marks. The cork is then completely screwed on.

To fill and check the lubricant level in the gearbox housing, place the walk-behind tractor on a flat surface and clean the gearbox housing in the area of ​​the filler hole. Then loosen the filler bolt. If the level is correct, then oil will begin to flow from the hole. If this does not happen, it is necessary to unscrew the bolt completely and pour oil into the gearbox until it flows out of the hole.

An important nuance is the proper condition of the air filter. Indeed, without an air filter or with a filter, but without the required oil level, you cannot start the engine. To add lubricant, unscrew the nut on the filter cover, pull the filtration element out of the sump, fill in oil up to the level of the mark on the oil bath body. Reinstall the filter element and tighten the nut.

Based on the above, before buying oil, you need to understand a few important points:

1. Decide on the season to use the oil.
2. Purchase special additives to enhance the properties of the lubricating fluid.

With the right choice of product, a long service life of the unit is ensured and its performance is improved.

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 analogues 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, this oil does not have increased requirements for the level of ash and smoke. Their level reaches elevated rates (ash content - more than 2%).

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

Many consumers wonder what is the difference between 4-stroke and two-stroke engines. A predetermined amount of lubricant is constantly maintained in the crankcase of a four-stroke power unit. From there, it is fed into the lubrication system under the influence of the oil pump.

As a result, an oil film forms on the pistons. In this case, there is no friction when it slides along the walls of the cylinders. In order to prevent the penetration of oily liquid into the combustion chamber, oil scraper rings are installed that cut off lubricant leaks, directing them back to the crankcase.

The lubrication system of two-stroke engines is based on mixing fuel with engine lubricant in a ratio of 50/1. Modern automotive oils have the unique property of self-mixing. With a lack of substance for the full lubrication of the working surfaces of the cylinders, the power unit operates “dryly”. At the same time, the overall life of the engine is sharply reduced.

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

The disadvantage of 2-stroke lubrication systems is the reduction 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 power unit. In this case, a large release of unburned mixtures into the environment occurs.

Differences between 2 and 4-stroke oils

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

1. For two-stroke engines, a prerequisite is the ability of the most complete combustion of oil. In this case, a minimum amount of soot (soot and ash) is formed.
2. In four-stroke engines, the main requirement for engine oil is to provide long-term lubricating effects by maintaining the beneficial properties of the material used.

Previously, in the manufacture of lubricants, the method of simple oil distillation was used. The resulting product was suitable for lubricating parts and assemblies, engines of any kind. Their technical characteristics met the requirements of motors with low power, low friction and low wear at the interface of parts.

With the growth of performance indicators and engine speeds, it became necessary to create motor oils with new capabilities. Additives began to be added to lubricating fluids, which significantly improve the technical parameters of lubricant products:

• reducing wear;
• antioxidant;
• antifoam;
• extreme pressure;
• washing.

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

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

Four-stroke engine oil is not recommended for two-stroke powertrains. When the mixture is burned, ash is formed, which forms a deposit in the combustion chambers and pistons.

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

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

Carbon ash and soot deposits on pistons and cylinders cause detonation. The operational resource of the power unit is sharply reduced. Coking of electrodes and spark plugs leads to their short circuit and engine blocking.

Varieties of four-stroke motor oils

The most popular among users is a four-stroke engine oil that meets the specifications of JASOMA-2, APISN. Domestic oils produced 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 motor oil. It does not form deposits, has many positive characteristics. It is used for extreme travel.
2. Semi-synthetic and mineral high-quality lubricants are wear-resistant, smoke-free during combustion, and keep the engine clean. Recommended for daily use.
3. Special semi-synthetics. These types of lubricants are used when operating on low-grade fuels. Thanks to the incoming additives, this oil is characterized by excellent detergent properties, low waste consumption, and preservation of useful qualities over a long period.

The right choice of 4-stroke engine oil

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

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

• grease used in engines in summer, SAE 20, 30, 40;
• winter materials from SAE 0W to SAE 25W;
• multigrade automotive oils.

In addition to the basic base, all seasons contain special additives. They dilute the lubricant to speed up the start of the engine in the 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.

Designation of all-weather motor oils according to SAE: 10W30, 14W40, etc. The numerical designation in front indicates the lowest air temperature at which this oil will not begin to thicken. The last digits are the maximum allowable ambient temperature for normal, uninterrupted operation of the motor in the summer heat.

Quality oil selection according to API specification

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

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

The use of a lubricant of a higher class is impractical. However, if the operating conditions are more difficult, it is recommended to use engine oil with a higher viscosity index.

Lubricant for air-cooled engines

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

In vehicles with worn four-stroke engines, it is also recommended to use more viscous lubricants to reduce losses.

What oil to use in older 4 stroke engines

For older models, all lubricants of modern brands are suitable. The main thing to remember is that synthetics are characterized by greater fluidity compared to mineral counterparts.

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

In order for the walk-behind tractor to work flawlessly for a long time, it must be properly maintained and operated. Oil is a key factor in keeping an engine running. We will try to figure out what kind of oil to fill in the engine of a walk-behind tractor on this page of the site.

The most correct recommendation for the selection of oil will be the recommendation of the engine manufacturer for the walk-behind tractor. Therefore, we will familiarize ourselves with the operating instructions for the main engine manufacturers for walk-behind tractors and give excerpts from the instructions.

The choice of engine oil, like any other type of oil, depends on two main parameters - the operating category and the viscosity class.

CLASSIFICATION OF OIL TYPES
API classification by operating category (American Petroleum Institute). For more details see

CLASSIFICATION OF OIL GRADES BY VISCOSITY
SAE (Society of Automotive and Transportation Engineers) classification. See more

In short:

Winter- with the letter W (Winter). Oils that meet these categories are low viscosity and are used in winter - SAE 0W, 5W, 10W, 15W, 20W, 25W

Summer- no letters. Oils that meet these categories are high-viscosity and are used in summer - SAE 20, 30, 40, 50, 60.

All season- at the moment, universal oils are most widely used, which are used both in winter and in summer.

Such oils are designated by a combination of winter and summer series: 5W-30, 10W-40

In winter, use an oil with a lower SAE number (less viscous), and in summer an oil with a higher SAE number (more viscous).

The multi-viscosity oil has all-round stability in the face of seasonal and temperature changes. For example, an SAE 10W-30 type oil is suitable for use as an all-weather oil. At low temperatures, it is equivalent in viscosity to SAE 10W oil, and in operation it has the same lubricating properties as SAE 30.

Motoblock engine brand	Engine oil recommended by the manufacturer
	summer	winter	operating class
Robin Subaru (subaru)	SAE 10W-30 - in moderate climates	SAE 5W-30 - in cold regions	Automotive engine oil; SE class or higher (recommended SG,SH or SJ)
Honda (Honda)	SAE 10W-30 oil is recommended for use at any temperature. If you wish to use a seasonal oil, then choose an oil with an appropriate viscosity grade based on the average temperature in your area.		SG, SF.
Lifan (lifan)	SAE-30	SAE-10W-30 - all season
Briggs & Stratton(briggs)	When operating below 0°C, Briggs & Stratton recommends the use of synthetic oil. If you do not have synthetic oil, you can use non-synthetic oil Briggs & Stratton 10W-30 part 998208 Note: Synthetic oil that meets the ILSAC GF-2 certification mark, API and API service symbol of “SJ/CF ENERGY CONSERVING” or higher can be used in all temperatures. Change synthetic oil according to the usual schedule. Air-cooled engines heat up faster than car engines. Using a non-synthetic thickened oil (5W-30, 10W-30, etc.) above 4°C will result in high oil consumption. If such oil is used, the oil level should be checked more frequently.		SF, SG, SH, SJ or higher
DM-1-01 (JSC Kaluga engine)	M6 3 /12G 1 or M5 3 /10G 1 GOST 10541-78, oil that meets the requirements of API: SF; SG; SH and SAE: 10W30; 15W30

Engines of these brands are installed on almost all currently produced walk-behind tractors such as Neva, MTZ, Salyut, Cascade, OKA, Ugra, Tselina, Tarpan, Agat, Favorit, MKM and many others.

Motors of such well-known companies are tested and tested on the indicated oils, therefore, the result of operation in accordance with the recommendations of the manufacturers will be the best. Using engine oil of the specified grade and viscosity will greatly extend engine life and performance. Using too little or too much oil can cause serious problems, including engine seizure.

In gasoline engines for general use, only SE, SF, SG engine oils should be used.

SA	For low stress applications where additives are not required
SB	For use in the medium stress range. It is characterized by low oxidation, stable lubricating properties, protects engines from wear and prevents corrosion of bearings.

• when changing the oil, drain it on a hot engine by unscrewing the drain and filler caps
• do not use additives and oil additives
• dispose of used oil in an environmentally friendly way, do not dump it on the ground, do not throw it in a trash can, the best option is to take the oil in a closed container to a local recycling center.

Please note that there are engines that have an additional gearbox built in, which also requires periodic oil changes. Here is an excerpt from the owner's manual for the Honda engine.

Tips for choosing engine oil for gasoline generators
There are several classifications of motor oils, we will focus on the following classifications:

1. Classification of oils according to the combination of operational properties API
2. Classification of oils by viscosity S.A.E.

API engine oil classification for gasoline engines
class description
SL For all engines Engine maintenance recommendations. Tips for choosing engine oil for gasoline generators: There are several classifications of engine oils, we will focus on the following classifications:

3. Classification of oils according to the combination of API performance properties

4. Classification of oils by viscosity SAE

Vehicles currently in use. SL grade oils are designed to provide the best high temperature properties and reduce oil consumption.
SJ For car engines up to 2001 of release.
SH For car engines up to 1996 release.
SG For car engines up to 1993 release.
The API classification distinguishes between oils for gasoline and diesel engines. The first corresponds to the letter S, for example - SH, SJ or SL, while the second letter indicates a higher level. So, the SL class was put into practice, improving and partly replacing the SJ engine oil class. API - American Petroleum Institute (API - American Petroleum Institute)

SAE engine oil classification for gasoline engines
Classification Application at ambient temperature Designation
0W30 0W40 0W50 5W30 5W40 5W50 -40°…+20° -40°…+35° -40°…+45° -30°…+20° -30°…+35° -30°…+45° "Winter oil"
10W30 10W40 10W50 ?25°…+30° -25°…+35° -25°…+45° "All-weather oil"
15W30 15W40 20W30 20W40 -20°…+35° -20°…+45° -15°…+35° -20°…+45° "Summer oil"
SAE (Society of Automotive Engineers - American Association of Automotive Engineers) describes the properties of viscosity and fluidity - the ability to flow and, at the same time, "stick" to the surface of the metal. The SAE J300 standard divides motor oils into six winter grades (0W, 5W, 10W, 15W, 20W, and 25W) and five summer grades (20, 30, 40, and 50). The double number means multigrade oil (5W-30, 5W-40, 10W-50, etc.).

The combination of summer and winter viscosity values ​​does not mean an arithmetic combination of viscosity properties. So, for example, 5W-30 oil is recommended for operation at ambient temperatures from? 30 to +20 degrees. At the same time, summer oil 30 can operate at temperatures up to 30 degrees, but only at ambient temperatures above zero.

In general, the term "recommended for use" is very, very conditional. Each engine of a certain brand of car, or a gasoline internal combustion engine for special equipment, is distinguished by a unique combination of the degree of forcing, thermal stress, design features, materials used, etc.
For gas generators, use high quality 4-stroke engine oils that meet the requirements of automakers for service of at least SG class. It is highly desirable to use motor oils corresponding to the SL class according to API, which have the appropriate marking on the package. SAE 10W30 engine oil is recommended as a universal oil for operation at all temperatures. Using the given data to select the optimal oil viscosity according to the temperature of the environment in which you are going to operate the generator, you can choose a different grade of oil.

The ideal condition for the normal operation of the gas generator is the use of SL class engine oils with viscosity characteristics according to SAE suitable for the ambient temperature in the place where the gas generator operates.
Recommended oils. API class not lower than SJ
Above 4°C 10W30, 10W40, 15W30, 15W40, 20W30, 20W40, SAE 30
At temperatures from 18°С to +4°С SAE 0W40, 0W50, 5W30,5W40, 5W50, 10W30, 10W40
At temperatures above 4°C, multi-temperature oils (10W-30, etc.) are consumed to a greater extent and can cause engine wear. When using these oils, check the level more often than usual. When using SAE30 at temperatures below 4°C, starting may be difficult and the use of this oil may cause premature engine wear due to lack of lubrication.

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 Sae-marked oil, which must be poured into the engine at an air temperature of at least 5 ° C. It includes a multifunctional additive package with anti-wear and anti-corrosion characteristics.

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

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

Scout-5l oil also has exceptional lubricating properties, which has gained a high reputation among domestic owners of walk-behind tractors and can be called a full-fledged analogue of Sae 30. It is comparable to it 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 2-stroke oil and 4-stroke oil?

Some types of engine oil are designed for four-stroke power units, while others are for two-stroke ones. They are not interchangeable and must be poured according to the intended use, because lubricants for motors with different duty cycles have different requirements. So, oil for four-stroke engines, where a forced lubrication system is used, is designed for long-term exposure and is designed to provide a more stable coating of parts. In 2-stroke engines, the oil enters along with the fuel and should instantly dissolve in it, burning smokeless with a minimum of deposits in the form of soot and ash. Therefore, a characteristic feature of 2-stroke oils is their good cleaning and the minimum content of aggressive additives. They, unlike 4-stroke fluid, do not contain ash, anti-seize and anti-wear additives, which allows them to almost completely burn out along 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 their efficiency. And if you pour such a mixture into an engine with a two-stroke duty cycle, this 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 only be eliminated by doing a complex and expensive repair of the walk-behind tractor motor. Soot also causes a lot of harm, which clogs the air filter and settles in the grooves of the piston rings if an inappropriate oil product is used. The accumulation of soot is fraught with loss of mobility of the rings, and this is a direct way to reduce the power of the walk-behind tractor engine, worsen its operation and even completely fail.

Classification of motor oils

The most important parameters of engine oil are the degree of viscosity and the temperature range in which it can be used. In the marking, the number before 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 intended for the use of equipment in the summer, and low-viscosity lubricants, for example, 5W30, are for its winter operation. A low-viscosity oil product at high temperatures will quickly evaporate and will not be able to provide full lubrication of the mechanisms. Too thick liquid will become an obstacle in starting the engine at low air temperatures.

The chemical composition of the lubricant base 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 sediment and soot;
• reduces wear of working parts;
• does not form harmful emissions 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.

Advantages of synthetic and semi-synthetic motor fluid:

• increased fluidity;
• low evaporation;
• low waste consumption.

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

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

Below are the most popular brands of summer oils marked Sae 30, as well as those intended for all-weather use.

Choosing the best oil for 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 affected 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 improperly performed 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 motorcycle engines are available in a fairly wide range - from budget to more expensive. 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 intended for gasoline engines, and the letter "C" - for diesel engines.

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

How much should be poured?

Cultivators, mini tractors and walk-behind tractors supplied to the Russian market are mainly equipped with Subaru, Briggs&Stratton, Honda power plants or their Chinese counterparts. They can be of different capacities and contain different amounts of lubricant. How to find out how much lubricant to pour from a canister so that a 4-stroke engine runs optimally and its parts do not wear out due to a lack of lubrication?

Lubricant consumption rates can be found in the operating instructions or technical documentation attached to motor vehicles.

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

	Required volume, l
Subaru EX21D (7.0 HP)
Subaru EH34B (11.0 HP)
Briggs & Stratton (8.0 to 13.5 hp)
Honda GX-390 (8.0-13.0 hp)

You can simply fill in motor lubricant by determining its amount by the dipstick on the plug. The minimum level is practically limited by the length of the probe itself, and the maximum level reaches the thread of the drain hole. You can also navigate by looking into the opening of the crankcase.

As a rule, about 0.6 liters of liquid are placed in a walk-behind tractor with a 6-8-horsepower engine, and a little more than 1 liter in more powerful units. It is not without reason 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 of medium-power motor vehicles, which are most in demand among owners of garden and summer cottages.
