Just as you should change the oil in your car, truck or chainsaw regularly, so should your lawnmower.
If you want to have the most beautiful lawns on the street, your lawnmower needs to have a sharp knife and be filled with the best oil so that the engine works well while you push the damn thing.
You might be tempted to think of your lawnmower as “just a lawnmower” so any type of auto oil is suitable for cars. However, this could mean the difference between whether you are extending the life of your lawnmower or clogging it and rendering it inoperable. This is especially true if your mower is not used very often. Read more information here.
So if you want the “good oil” for your grass cutter, read on.
What type of oil do I need to use in my lawnmower?
The temperature of the climate in which you operate the lawnmower affects your oil requirements.
Briggs and Stratton lawnmower experts recommend: “Most outdoor power equipment engines work well with 5W30 synthetic oil. Vanguard 15W50 synthetic oil provides the best protection for devices that operate at hot temperatures.”
For you as an oil user, this means that you have to check in which area your engine is running. The easiest way to do this is to check your engine's owner's manual for the manufacturer's recommendations. If you've lost the manual or never had one, use a search engine to find a PDF of it.
Can I use synthetic oil in my lawnmower?
Yes, you can use synthetic oil in a lawnmower. Oils like Amsoil are designed for more modern engines.
Synthetic oil is a small engine lubricant full of chemical compounds that are artificially made from chemically modified petroleum components.
The advantage of using synthetic oil is that it tends to provide better viscosity, wear and deposit control, and flowability at low temperatures.
This means that if you regularly (long-term) use synthetic oil in your lawnmower, you significantly increase the chances of long life and reduce the need to replace your lawnmower in the 6th year instead of the 10th (excuse the exaggeration!).
Regular use of synthetic oils in your engine reduces the likelihood of failure and thus extends the service life.
