What’s the best engine oil for your power tiller?. Selecting an oil grade with engine requirements

Engine oils for power tillers. types and characteristics

A modern single-axle tractor consists of a variety of mechanisms that require lubricants for proper and coordinated operation. On the quality and properties of the latter depends not only the durability of the aggregate elements, but also the efficiency of its use in certain conditions.

The engine is called the “heart” of a power tiller for a reason. It is the condition of the first that largely determines the performance of the machine. The engine, in its turn, will not be able to operate without properly selected engine oil.

The latter performs several important functions at the same time:

• cools the engine of the power tiller under heavy loads;
• lubricates the rubbing parts of the engine;
• cleans the internal engine cavities from blockages;
• seals the fuel mixture, making it of higher quality.

During the operation of an air-cooled engine, the lubricant used evaporates and accumulates on the surface of the hot cylinder. as a result, oil, together with fuel, turns into smoky exhaust. All the products of fuel combustion that gather on the parts of a single-axle tractor make lubrication much more difficult. To avoid this, many companies-manufacturers of motor-blocks advise to use special antioxidants together with the lubricant, whose task is to clean the engine parts from harmful deposits.

All commercially available motor oils are divided among themselves according to the SAE system.

According to it, the market distinguishes between the following lubricants:

• summer oils. these products are designed mainly for summer time. They have a high viscosity, and their packaging does not have a letter marking. These compositions include the means SAE 20, SAE 30, SAE 40;
• winter oils. materials of this type are used for lubricating engines of motor-blocks in winter. They are characterized by low viscosity and the presence of the letter W in the marking, which stands for “Winter. winter oils include compositions SAE 0W, SAE 10W, SAE 20W;
• multigrade oils. these formulations are in the highest demand. They are universal as they can be successfully used both in winter and summer. They are double marked on their packaging. These oils include 5W-30 and 10W-40.

To select oil for a motorblock, you should also take into account its composition.

Manufacturers produce engine lubricants with these compositions

Also available on the market are oils for both 2-stroke and 4-stroke engines. Most modern power tillers and tractors have 4-stroke engines with built-in air cooling systems. Such motors should be filled exclusively with 4-stroke oil.

A forced-air-cooled motor heats up considerably more than an actively water-cooled one. In this regard, the oil in a single-axle tractor with such a cooling system must have high thermal-oxidative stability and a fairly low evaporation. In addition, the oil used for engine lubrication must meet all known modern requirements of environmental friendliness, in other words, to show the permissible level of toxicity of exhaust gases and smoke.

Marking

Which oil to use in a single axle tractor and which oil grade to use depends on the make of your tractor. If you have a diesel single axle tractor use diesel, winter or summer oil, it depends on the season. In a petrol single axle tractor use SAE 30 semi synthetic 5 W 30 or 10 W 30, if using in winter 0 W 40.

When choosing an oil, pay attention to its viscosity and performance categories. The viscosity determines the climatic conditions under which the single axle tractor will work. These are multigrade, summer high-viscosity and winter low-viscosity oils.

What kind of grease to use?

There are two types of grease for power tillers:

In this regard, it is necessary to pour exactly the type recommended by the manufacturer, taking into account the number of strokes of a particular brand of power tiller. Synthetic and semi-synthetic oils, which are perfectly suitable for use in power tiller engines, have become the most widespread in recent years. In specialized stores the customer is offered a range of different types of foreign and domestic production.

How to make the right choice

An important factor in selecting an engine oil is its chemical composition. Minerals are excellent for reducing the frictional force of components, thus reducing wear on the unit. Semi-synthetic oils provide more stable engine operation. But they have an increased fluidity, which is not suitable for engines with a heavy wear on the components. Synthetic oils prevent the formation of carbon deposits, protecting the engine from breakdowns.

The engine oil to be filled into a single axle tractor must meet the following requirements:

• Reduced kinematic viscosity over a wide temperature range. This is necessary to avoid oil starvation during engine warmup.
• The oil must have a low coking rate. This is especially important for air-cooled engines.

The lubricant performs several functions when the machine is in operation: cooling, cleaning, lubricating, and sealing.

Changing the oil in your power tiller with your hands

Change the oil in the tractor engine for the first time after the break-in period, at idling speed with strict controls. Replace with new oil an hour after operating the machine under load.

Let the engine warm up. It is recommended that you service the engine every 40 hours.

• Warm the engine up.
• Position machine on level, horizontal ground.
• Place a container in which to catch the used lubricant.
• Open the filler plug and drain plug.
• Drain the liquid.
• Screw in the drain plug.
• Fill with new oil.
• Close inlet opening.
• Allow to stand.
• Using a feeler gauge, measure the lubricant level and top up if necessary.

Start the engine, and check the joints for leaks.

Changing the oil in the gearbox follows the same scheme and in the same sequence.

Is it necessary to add oil to petrol for your Moto-Block??

Fuel for your Moto-Block may be clean, or it may be necessary to prepare a fuel mixture. Everything depends on the type of engine. For two-stroke engines gasoline for a motorblock must be diluted with oil. In this case, you should clearly observe the proportions that manufacturers recommend (often this proportion looks like 1 part of oil to 4 parts of gasoline). Four-stroke engines do not require such a mixture and are filled with pure gasoline.

It is also important to note that motoblocs, working on diesel, in no case need such mixtures (all diesel engines are 4-stroke). Otherwise, everything can end in a serious breakdown of the unit.

Oil for your Moto-Block. what to remember when choosing?

According to API standards, lubricating compositions are divided into three types. for gasoline engines, for diesel engines and universal oils, which can be used for all types of internal combustion engines.

If you use gasoline for your power tiller, you must buy motor oil with a two-letter code on the package to lubricate the engine. The first letter must always be S, and the next one must be one of the letters A, B, C, F, G, H or J. If you use diesel fuel for your power tiller for refueling, then in order to lubricate the engine you must buy oil with the letter C in the package first.

Universal motor oils are marked with a double marking, which indicates the possibility of using them to lubricate both types of internal combustion engines. Such engine oils, for example, may be marked as SG/CD or SF/CC.

Checking the level

To control the level in the engine crankcase, most models have a dipstick with markings min and max (minimum/maximum). When the dipstick is removed from the crankcase, oil is still present and indicates the oil level. 5W-30 If it does not appear accurate, wipe probe clean with a cloth, put it back in the crankcase, and remove it. Oil is sure to remain on the dipstick and show its level.

It is not allowed to overfill either the gearbox or the engine of your power tiller. You cannot pour more oil than the lip of the hole, because it will immediately drain back out. And the level at the edge of the hole is acceptable for the engine. It is normal to have too much oil in the gearbox. This is why there is no dipstick for the oil level in the gearbox.

To check the oil level in the gearbox, you can use a handy dipstick. a piece of wire, etc.д.

For some engines, overflowing oil in the crankcase is inadmissible. This can lead to increased pressure inside the unit, squeezing glands and gaskets, splashing. If piston rings and cylinder mirror are worn out, oil can also get into the combustion chamber and onto the spark plugs, which is highly undesirable. Therefore, it is better to fill the engine with oil according to the recommendations in the Operation Manual.

The quantity and quality of oil must be monitored, the service life of the entire motorcycle depends on it.

Some people change the oil every spring, just before the start of the season. Other owners do not change for years. Still others put the counter of motor-hours and change it according to the manufacturer’s recommendations. For example, every 500 engine hours.

It makes sense to change the oil after the running-in period, because at that time it may contain fine filings, metal chips, which are formed during lapping of new assemblies. These inclusions in oil are extremely undesirable because they already lead to the wear and tear of units.
