Motor oils play a vital role as far as the functioning of lawnmowers is concerned. They must be replaced after every 35-50 hours of operation. You cannot go about using any kind of motor oil for your mower as that depends on several factors like the type of engine, the surrounding temperature, and a lot more. A minute read of the manufacturer’s guide helps in taking the best decisions.
Type of engine: You’ll generally find mowers with two types of engines – 4 stroke and 2 stroke. 4 stroke engines are usually the ones that come in large lawnmowers. . Unlike the 2- stroke lawnmowers, where gas and oil are stored together, in the case of 4-stroke lawnmowers, there is a separate compartment for both.
- If your lawnmower has a 4 stroke engine, then oil with a grade of SAE-30 should work fine. Oils that are suitable for cars and trucks might work for your lawnmower as well. Try looking for oils that are SF, SG, SH, SJ, or higher. However, on the safer side, it is always better to check the manufacturer’s website, user guide/manual provided to you for the instructions and information about the type of motor oil that works best for your lawnmower.
- Some lawnmowers have 2 stroke engines. They require a different type of oil as they burn gasoline and oil at the same time. Here, oil and gasoline are mixed in a particular ratio before sending it to the tank. A two-stroked oil that is used for air-cooled engines works for a 2 stroke lawn mower as well. But, as said, it is always better to confirm from reliable sources and then act accordingly.
Surrounding temperature: If you are living in colder weather conditions, then go for SAE 5W-30 motor oil. If the temperature ranges between 0 to 100 degrees, then SAE 10W-30 is the right choice. However, if you are set to use the lawnmower in warmer weather conditions, then you can try considering SAE 30 as the option. Point to be noted, all these are just the possible options that one can choose from. In the end, what matters is choosing the right after thoroughly reading the user guide for you definitely wouldn’t want to screw things up and waste money, right?
