What Oil Is Best To Pour Into A Lawn Mower

Everyone knows that the car engine requires special care, which will ensure a long and trouble-free life for the motor. The same rule applies to the gas mower engine: depending on whether you have a trimmer or a large four-wheel mower, you will encounter the problem of choosing an oil. So what are the basic requirements for oil for lawn mower engines?

How to choose a lawn mower oil?

As with any machine, there is a manual for the lawn mower, which not only describes the main characteristics of the tool, but also the rules for caring for it. So, in the instructions it will be written that for lawnmowers it is necessary to use only specialized oil. And some manufacturers insist on using the same brand of oil as the mower itself.

In fact, this fact turns out to be just a marketing ploy of manufacturers, and both automobile and motorcycle engine oil for four-stroke engines can be suitable for a lawn mower. It is enough to simply observe the basic rules:

1. The oil must be mineral or semi-synthetic. A fully synthetic oil can burn the engine, so it is best not to use it at all. During operation of the lawnmower, a lot of sludge is formed on mineral oil, so we advise you to choose semi-synthetic oil. In addition, mineral oil is difficult to find today.

2. The viscosity of the oil must not exceed SAE 30 or 10w30, and the quality category vary between SE and SJ. A more viscous oil can disrupt the engine, however, also applies to a less viscous oil. All these indicators must be indicated on the package.

3. Choose the oil according to the temperature conditions. If you mow in cold weather, the viscosity of the oil may be higher than the above, but the next time you turn it on you will have to replace the oil with the right one.

In lawn mowers with four-stroke engines, oil is poured into a special crankcase and never mixed with gasoline, since the design of such a gas lawn mower does not imply a mix of oil and fuel. On the contrary, it can cause engine damage. Changing the oil is enough once a season, as usually the crankcase holds from 450 to 600 ml of oil. This is enough to handle large areas. However, do not be lazy to check the oil level before each use of the tool.

How is oil used in two-stroke engine lawn mowers?

As a rule, a two-stroke engine is mounted on trim tabs, and since their design does not imply the presence of extra parts, a separate oil tank is not provided. What to do in this case? Prepare the fuel mixture.
For two-stroke engine lawn mowers, the same rules apply as for their larger counterparts, with one exception — you need to buy oil for units with a two-stroke engine.

On each trimmer (or in the instructions for it), the proportions of mixing fuel and oil are indicated: from 1:32 to 1:35. This rule applies only to mineral oil! And since it’s quite difficult to find it now, and it can scare off the cost, semi-synthetic or even synthetic oil is most often used. Note that the mixing proportions in this case change, and become. 1:50. If in doubt, carefully examine the oil packaging; this data is usually indicated on it. You should focus on them. To prepare the mixture, it is enough to pour 100 ml of oil into five liters of gasoline, this should be enough for a whole season of regular beveling. If not, repeat the procedure.
