How much oil to put in the lawnmower?
The ideal ratio of oil to gasoline is 50:1, where 50 parts of fuel takes 1 part of the lubricant. For example, you would need 20 milliliters of oil for 1 liter of gasoline, or you would need 100 milliliters of oil for 5 liters of fuel. Important!
Tilt the mower deck and place newspaper and an oil pan or jug under the mower. Use a socket wrench to unscrew the plug counterclockwise to drain the old oil.
Features of lawn mowers
Despite the fact that the overall design of four-stroke lawn mower engines are similar to automobile, they still have important differences: in order to reduce the price of the product at the lawn mowers excluded oil pump and generally the system of oil supply, it increases the requirements to the viscosity used in the motors of garden equipment.
Lawn mower engines distribute engine oil via the crankshaft: it is scooped out of the crankcase and sprayed onto the parts. Because of this design, the viscosity of the grease should be sufficient to keep the oil film on the parts while not being too thick so that it would interfere with component movement or form a hard crust.
lawnmowers, on the other hand, operate mostly at positive ambient temperatures and their engines are not under as much strain as car engines. Lawnmowers most often do not require a “cold start” in the cold, which greatly reduces the life of a car engine and requires low-temperature properties from the lubricant.
On the contrary, lawnmowers are usually air-cooled and therefore tend to have higher engine temperatures than liquid-cooled car engines.
The first filling is designed for running-in of the engine. after five hours of work it is replaced, and then the new grease can be used for the whole season. In the future, replace it according to the regulations after a certain number of moto-hours, or drain it at the end of the dacha season and pour a new one the next year.
General recommendations for lawnmower oil selection
Based on the above engine design features, it is best to use a special lawnmower oil for lubrication, and it should be appropriate for the temperature conditions in which the unit will be used. Specialized SAE 30 grade grease is considered optimum. It is used at temperatures above 5 degrees.
If special is not available, you can use automotive grade lubricants:
These greases, too, are designed mainly for positive ambient temperatures and a maximum value above 35 degrees.
According to the type of lubricating fluid. mineral and semi-synthetic are acceptable. Fully synthetic would be too expensive. API performance level. “SF”, “SG”, “SH”, “SJ” and higher. Gardening equipment four-stroke engines should be marked with “4T” on the label.
Why is it so important to keep the intervals?
Let’s start by examining how important it is to periodically change the oil in the lawnmower. Firstly, this fluid provides air cooling of the mechanism, thereby allowing the engine to work at extremely high speeds. Secondly, the lawnmower oil protects the lawnmower during winter storage.
It is worth noting that the frequency of oil replacement directly depends on the technical condition of the engine. If, for example, the engine is new, the fluid must be changed immediately after the lawnmower has run-in. In terms of time, it is about 5-6 hours of operation of the mechanism. To prevent further debris from penetrating and accumulating in the engine, it is necessary to make fluid replacement a few more times at intervals of 5-10 engine hours.

If the engine is not new, lawnmower oil can be changed approximately every 25-50 hours of operation of the tool. This is an average of 2 to 3 months of operation. You can also tell the condition of the oil without measuring the number of hours it has been in use. Just make sure that it does not start to turn black. When this happens, be sure to change the fluid, otherwise the engine may soon simply seize up.
Oil for air-cooled four-stroke engines
Engine oils for air-cooled 4-stroke drives differ from those for water-cooled engines. When selecting oils, it is therefore necessary to consider the make and composition of the fluids and the type of engines for which they were developed.
Air-cooled four-stroke engines are characterized by high cylinder-piston group temperatures. Oil does not mix with fuel and does not enter the combustion chamber, therefore, the engine mixture for this type of drives must have the following properties:
- Increased number of additives in the engine fluid. up to 25% of total volume.
- Stability of viscosity characteristics at different temperatures. Lubricant should provide quick and easy engine starting, as well as instantaneous oil supply to all working elements of the drive.
- Thermal and oxidative stability. The structure of the mixture must be resistant to oxidation reactions, so that it does not form deposits and soot, and also the mixture does not become the water structure.
- Improved anti-wear and extreme pressure properties to protect engine components from tribological loads.
You should not use motor oils designed for water-cooled engines in 4-stroke air-cooled engines, these two types of oil contain different additive composition, the first are designed to heat the cylinder surface to a temperature of 160 0C, and for the second this parameter is. 220 0C.
Watch a video about the classification of engine fluids:
Lubricant labels are hard for the average consumer to understand, so it is not uncommon for unscrupulous sellers to give out fluids for 2-stroke engines instead of 4-stroke.
Buying these products will shorten the life of the drive, so before you go to the auto store, check the generally accepted standards that indicate the engine oil is suitable for air-cooled four-stroke drives:

- The performance class according to the API system must meet the requirements of SF/CC, at least.
- According to State Standard, the motor oil for these engines corresponds to group G.
- The SAE standard requires that the fluid meet the requirements of the vehicle dealer. This information can be found in the service book or on the filler cap. For air-cooled engines, it is advisable to use oil that has an SAE 30 designation. summer grade motor mixes, this grease is thick enough not to disperse quickly at high operating temperatures.
When selecting the base oil base, for engines with air cooling system take into account
- Mineral oil. reduces friction force, reduces wear of drive elements, when burned it does not form soot and smoke, you can use leaded or unleaded type gasoline.
- Semi-synthetic. used with low-quality fuel, recommended for heavily-loaded engines, provides structural stability during operation, but is more fluent, suitable for leaded and unleaded gasoline.
- Synthetic. prevents fouling, protects engine from wear, can only be used with unleaded fuel.
When choosing a lubricant, consider the season when the vehicle will be used, because summer types of oils begin to crystallize at a lower temperature.100C, winter ones can withstand250C, all-season, protects the engine at any time of year. For their operating temperature range, see the SAE classification.
The canister with a quality product indicates that the lubricant is suitable for 4-stroke engines with air cooling.
Properly selected fluids must meet the requirements of the vehicle dealer to ensure proper engine operation. Preference should be given to products of famous brands that have a quality certificate from the retailer.
Improperly selected motor oil will lead to increased carbon buildup, higher fuel consumption, and rapid engine damage.
Choosing a particular brand of oil, note that motorcycle oils differ in the number of antifriction additives.
This is due to the mode of operation of power units, snowmobiles, for example, are designed for extreme modes of loading, and scooters are used under much better operating conditions.
Lubricants for these types of equipment will have different compositions and additives.
