What oil should I use in my lawn mower engine?

Before changing your lawn mower oil, you first need to take a moment to ensure you are adding the correct oil type and amount for the engine in your Ferris mower. The lawn mower oil recommendation may be different depending on the outdoor temperature you will be using your mower in. Briggs & Stratton offers a useful guide to determine the best oil type based on outdoor temperature.

It is also important to remember that the type of oil required may vary between different mower engine manufacturers. We recommend referring to the original engine manufacturer and consider outdoor temperature to find the best engine oil for your mower.

Other things to keep in mind when choosing your lawn mower oil:

  • Avoid special additives
  • Use high quality detergent oils such as "For Service SF, SG, SH, SJ" or higher.
  • You can also use synthetic oils, which are acceptable at all temperatures.
