As a rule, the manufacturer’s instruction manual for motor vehicles specifies the brand and amount of machine oil which is better to use. If there are no such recommendations, the product is chosen according to the following characteristics:
The SAE parameter indicates the viscosity grade of the substance and consists of an alphanumeric abbreviation, where the letter W indicates the possibility of use at low temperatures. The number in front of it indicates the viscosity at negative thermometer values, and the number after the dash at positive. These values describe how easily the fluid will be pumped through the system and how quickly it will reach the surfaces of the working parts without causing them dry friction.
The API parameter divides the lubricant into C and S categories according to its performance. Category C includes products for air-cooled four-stroke diesel engines and Category S for gasoline engines. Therefore, when choosing a fluid, you should always pay attention to this marking, because for a diesel and carburetor engine it has a different composition.
The ACEA parameter classifies the oil according to HT (viscosity at elevated temperatures)/HS (shear rate), which shows how energy-efficient the lubricant is. The higher the value, the better it protects engine components from wear and tear. Pour a substance with a high mPas value is recommended in a tractor, mini-tractor, as well as heavy motor blocks Neva, designed for heavy loads.
Below you will find the types of machine grease that are optimal for your cultivator or tiller. Of course, you may use them if there are no special recommendations from equipment manufacturer, and in accordance with S and C marks. So, these are oils:
- The engine oil 5w30, 5w40 all-season, which can be filled at ambient temperatures of at least 12°F.25 o C;
- 10w30, 10w40 have anticorrosive properties;
- 15w40, 20w40 intended for filling into engine at 45о C and higher;
- 0w30, 0w40 designed for winter application;
- MIL-L are designed for military vehicles and can be used on motor blocks with diesel engines (code 2104) and carburettor engines (code 46152).
Double-labelled (SG/CD, SF/CC) can be used for all engines: it is universal and equally suited to diesel and gasoline engines (such as Texas rotary cultivators). Among the variety of lubricant products the most popular is the product, produced under the brands Mobil, Castrol, ZIC, Shell Helix. To improve its action and quality, they add Oil Additiv, BIZOL, Cera Tec and other additives. They can be used at ambient temperatures from.25 O C to 25 O C.
First of all, you need to follow the instruction manual for your power tiller and only on the basis of this document you need to choose the right brand and type of lubricant. In this article we will discuss all the most important issues related to lubricant replacement in major power tillers.
Many owners of power tillers ask themselves a question, is it possible to use automobile engine oil for the lubrication of the main unit parts? Experienced mechanics responsibly declare that even if a sufficient amount of automotive oil is available, it is not recommended to use it for filling the single axle tractor.
The point is that a car engine and a power tiller engine have a different lubrication scheme and quite different operating temperature regimes.
In addition the engines of a Moto-Block and a car are different from each other:
Therefore, it is strongly not recommended to use automobile engine oil to keep your power tiller in working condition. In fact, the use of automotive leads to accelerated wear and tear of the cylinders and engine piston group as a whole, which eventually causes engine failure.
What oil to fill in a single–axle tractor Neva
The peculiarity of the Neva power tillers is the wide variety of modifications of the model range through the use of different engines, respectively, from different manufacturers. So before you choose oil for your tractor it is worth once again checking the instructions of the engine and consulting the manufacturer’s recommendations. To learn more about the specific features and technical characteristics of different models of tractors, please read the corresponding articles. Neva MB-2S-7,0, Neva MB-23S-9,0 Pro single axle tractor, as well as technical specifications and design of power tillers. Neva MK-100, Neva MK-200.
What oil to fill in a single axle tractor
When buying a power tiller the question invariably arises what oil to fill in a single–axle tractor. In any case, it is necessary to be guided by the instruction manual.
What oil to fill in a single axle tractor.
And you must fill exactly what is written in the manual. If you have a single axle tractor with a diesel, then accordingly you need to fill the oil with diesel, winter or summer depending on the season. If your single axle tractor has a gasoline engine and there is no manual or it doesn’t say what oil to use, you can pour SAE 30 semisynthetic 5w30 or 10w30. If you will work on your power tiller in winter. It may be expensive, but buying a new engine will be more expensive. We will not give recommendations on the manufacturers, but be wary of counterfeit products and buy oil in brand stores.
What oil to fill in a single axle tractor?
Many people wonder what kind of oil to fill in the engine motoblock? We should start with the fact that the oil in the engine of a power tiller is poured directly into the crankcase and not mixed with gasoline, as in the case of two-stroke engines, mainly used in chainsaws, trimmers, brush cutters, power drills and other small motor equipment. For this purpose there is a special oil for two-stroke engines. Thus, the oil for the engine of a motor-block must be four-stroke, comply with GOST 10541-78, or API requirements: SF, SG, SH and SAE, type of engine oil for motor-block: mineral 10W30, 15W30.

How to Check the Oil Level on a MotoBlock? Checking oil in the engine of a power tiller.
The oil level on any power tiller is checked by unscrewing the oil filler plug. The oil trail must be between the maximum and minimum marks on the dipstick. If there are no marks on the dipstick, it must be moistened to about the middle.
In the absence of the dipstick itself, after unscrewing the plug, the oil should be visible on the thread of the filler neck, in which, respectively, the plug itself is screwed, that is, the oil should almost, a little more and poured out.
When to change the oil in the engine of a motoblock? Oil change interval in a power tiller.
In a new engine of a power tiller the oil is to be changed after the first 5 (five) hours of work, then after every 25 hours of work, but experienced owners of power tillers change oil in the engine every spring, before the beginning of the season, regardless of the last year mileage, which in our opinion is the most optimal and correct.
9 Best Diesel Engine Oils 2018
Remember, any, even the most advanced engine of a Moto-Block consumes at least 1 gram of oil per hour of work (the so-called hourly rate of oil depletion), so the oil level must be watched carefully!
Running-in and operation of a 4-stroke engine
You have bought an air-cooled engine. The store didn’t explain how to start the engine. What kind of gasoline to fill up, what kind of oil to use? We do our best to help you with the basics.
What you need to know about running-in and operation of 4-stroke air-cooled engines installed on garden, construction and road motorcycle machinery.
Before operating a power tiller, snowmobile, alternator, pump, lawn mower, etc.д.), it is absolutely necessary to study the instruction manual. Many buyers, unfortunately, do not do this. From the first day the engine is running, the problems begin.
First: what kind of gasoline to use.
We recommend using 92 octane gasoline. Air-cooled engines are not designed for operation with AI95 and AI98 fuel. The 95-th and 98-th gasoline contains additives, which disastrously act on the engine piston group and valve system, leading to its failure.
Use fresh gasoline with a shelf life of no more than 30 days.
Second: what kind of oil to put in the crankcase.
Many people consider automotive oil of well-known brands to be the best for use in engines for a power tiller (motor cultivator, snowmobile, electric generator, motor pump, etc.).д.). This is absolutely not true. Automotive oils are designed to work in water-cooled engines, not air-cooled. Automobile oils have a lower boiling point than those containing special additives for air-cooled engines. Engine manufacturers recommend using SAE-30 API SG/CD (for summertime) and SAE 5W30 API SL (for wintertime).
Always keep an eye on the level. The oil level should be up to the last thread of the filler hole in the horizontal position of the engine. There are two oil fill and drain ports on each side of the engine. Pay no attention to the dipstick. It does not tell you the oil level accurately.
Different engines have different crankcase volumes. If you have a 4, 5.5, 6.5 or 7 liter engine.с. you have to fill up to 600 ml. oils. In 7.5 liter engines.с. 900 ml. In 8, 9, 11, 13 and 15 litre engines.с. respectively 1.1 l.
Third: starting the engine.
At the first or cold start of the engine, there is an increased load on the piston system. The engine can be damaged by high engine speeds. Therefore it is necessary to start the engine on 1/3 gas position. To run it in at medium speed.
Fourthly: How does the engine run-in?
Air-cooled engines do not like to idle. Start the engine and let it warm up for 1-2 minutes. and start working. Do not overload the machine and break it every 20-25 minutes. After the break, when the engine has cooled down (15-20 minutes).), you may restart the engine. In such a mode the engine should work first 4-5 hours, then it is necessary to change oil. Break-in period is finished.
How to choose an oil for your power tiller?
To get accurate information about the proper brand lubricant for the integrated motor of your power tiller, see the factory’s regular usage manual. As a rule, the manufacturer specifies the type of liquid, its base and brand. The manufacturer’s manual also contains the machine manufacturer’s instructions for how much lubricant to put in the factory engine and how to do it correctly.
But not everyone has the original manual of the used power tiller. In this case, the operator needs to remember that, depending on the original purpose, 2-stroke and 4-stroke factory oil is on sale. Most often, farm motor blocks are equipped with factory 4-stroke engines, but just before buying a lubricant, the user is still better to study the markings stamped on the wall of the engine in advance.
Depending on the type of grease base, the market distinguishes between semi-synthetic and synthetic branded oils for power tillers. In some stores of agricultural machinery you can still find mineral-based natural fluids, but synthetic greases are replacing them more and more. There is an opinion among experienced users that synthetic oils are universal and can be used at all times, regardless of the weather conditions. But this is not entirely true. The thing is that the composition of each type of technical liquid contains different natural components and additives, which lose their initial properties instantly at a sharp drop in temperature and freeze. That’s why factory engine oils are commonly divided by seasonality of operation. into summer and less viscous winter.
Another important factor when choosing a technical fluid is its density. The oil must envelop the moving parts of the engine of the motoblock, and for this purpose it must be evenly colored and sufficiently viscous. Don’t choose too thick a fluid, otherwise it won’t be able to seep into the smallest grooves in the factory engine.
Do I need to add oil to gasoline for my power tiller??
To find out whether it is necessary to dilute gasoline for a motor-block, it is necessary to study the instructions for its operation. It indicates what type of engine the unit is equipped with. 2 or 4-stroke.
If a single–axle tractor is equipped with a 2-stroke motor, the fuel mixture for it must necessarily consist of gasoline and oil. To reduce the risk of fire, do not operate your power tool if it is damaged or not properly assembled. At the same time, fuel for a power tiller with a 4-stroke engine does not need to be mixed with oil because all 4 strokes of such engines run on pure fuel.
It should be remembered that motoblocs, which are filled with diesel, also do not need to prepare a fuel mixture. The point is that all diesel engines are 4-stroke engines and work on pure fuel.
The machine has a passport and instruction booklet, which is included with each machine, including power tillers. Manufacturers always recommend in the instructions the types of oil that will allow the equipment to serve for a long time and not to break down.
It’s important to know that during the operation of a power harvester, the engine oil performs four functions at once:
When using an air-cooled motoblock engine, the lubricant burns and remains on the hot cylinder, resulting in a smoky exhaust. The amount of oil that is deposited dramatically increases the soiling of some parts and makes them more difficult to lubricate.
With oil, it is recommended to use an antioxidant that cleans the engine of dirty deposits. The correct SAE lubricant for your power tiller is the key to long service life.
When using a single-axle tractor, select a lubricant based on the climate zone.
For example, if you use SAE 10W30 type grease at 5°C or higher, its consumption will be much higher and there will be a greater chance of engine failure. It is undesirable to use summer lubricants at ambient temperatures below 5°C. This use makes it difficult to start the engine and damages the cylinder bore.
1.1 Classification of oil by viscosity grade
The viscosity grades of motor oils are generally classified according to SAE (Society of Automotive Engineers).
High-quality flushing oil MPA. 2
- Summer grades. oils belonging to this category are used in summer, have high viscosity and no letter designation. These include: SAE 20, 30, 40, 50, 60.
- Winter grades. these oils are used in winter and have low viscosity. The letter designation of this grade is W (Winter). These include: SAE 0W, 5W, 10W, 15W, 20W, 25W.
- All-season grades are the most popular at the moment, as they are used both in summer and winter. They are indicated by a double combination: 5W-30, 10W-40.
In addition to the differences of lubricants by seasonal characteristics, they are divided into two types according to their composition:
Also all oils are divided into greases for both 2-stroke and 4-stroke engines. The engine is usually equipped with air-cooled, 4-stroke engines. Only four-stroke oil should be used in these engines.
Check oil level with dipstick in oil filler opening
Air-cooled engine will run hotter than water-cooled engine under the same operating conditions. The in-fill liquid must therefore have low volatility and high thermal-oxidative stability. Also modern oils must be environmentally friendly, i.e.е. Check the amount of smoke and toxic exhaust fumes.
Since waste is often simply burned in boilers or steam generators, it must not contain ingredients that create toxic compounds when burned. It is better to pour 4-stroke oil of 5W30 or SAE30 grade into your power tiller, which works on gasoline, and has no instructions.
Winter or gear oil, e.g. 0W40 is preferable in winter. But you will have to pay for such quality. Do not save on this, because high-quality oil affects less engine wear and durability.
Changing the oil in the engine of a power tiller
It is necessary to change oil in a power tiller in strict compliance with the periodicity prescribed by the manufacturer. Some brands advise to do it every 30-40 hours of work with the technique, others. at least once every 100 hours of work. Following these recommendations, the user can protect the engine from high loads and significantly extend its service life.
The order of actions during grease replacement in the cold engine of a farm motor-block looks the same for both imported engines of Subaru brand, and for branded power units of famous Russian brands Zubr, Kentavr, Neva modifications of MB-1 and MB-2, as well as other popular manufacturers. To change the oil in the engine of your own motoblock, you need to:
- Place a deep, wide container under the bottom surface of the engine crankcase, just under the regular drain plug;
- Carefully pry up the plastic plug of the standard drain hole, remove it and wait for all the used engine oil to flow out;
- Pour about 2 liters of new factory lubricant into the empty crankcase and tighten the factory oil filler plug firmly.
To make it easier for the user to replace the old grease with the new one, it is better to use a watering can, which will not allow the oil to splash around the body of the agricultural machine.
What oil to fill in a gearbox of a crabby block?
The gearbox is part of the powerpack’s transmission, so transmission oils are used for it. There are no special oils for the transmission of power tillers, they use traditional transmission fluids.
Everybody knows the oil for a motoblock gearbox from soviet times. TAD 17, it was often used in Kaskad brand cultivators. Today on sale there are analogs with other markings. But often you can see the familiar marking on them in the Latin abbreviation TAD 17, or TAD 17a.
In addition to this marking, there are other marks today. For example, TM-4 80W85, where “TM” stands for “gear oil”.
Rotating units have no cooling, so they can greatly heat up the oil. Because of this, all transmissions are designed for high operating temperatures. For example, TM 4 up to 150C.
Many owners of power tillers have been filling up their gearboxes with regular motor oil since Soviet times. Yet they believe it lubricates better and protects the gears from abrasion. In any case, in the gearbox of a motor-block there are no high revolutions that cause rapid wear of parts and overheating of the oil.
But this does not mean that one can treat the quality and quantity of transmission oil in a motoblock gearbox irresponsibly. In a bad, old oil, with little or no oil, the assembly will fail sooner.
