Type of oil for a lawn mower. The type of oil that should go into a lawn mower will depend on the engine type. In general, small-engine oil will work in two-stroke engines, and straight oil typically works in four-stroke engines.
Finding out what type is best for your lawnmower involves looking at its manufacturer’s instructions to see if they suggest a specific brand or grade, but you can also refer to a table with this information available or ask someone who will know.
Also, consider the typical operating temperatures of your lawnmower. Lower temperatures may bring different grades into play, while higher temperatures might require oils formulated specifically for them (which could be more expensive).

For a lawnmower, how much oil should I use?
The manufacturer will recommend how much oil to use, and it’s vital to be as accurate as possible because overfilling or underfilling your mower could cause harm.
A plastic measuring jug can help you decide how much to add. Small lawnmowers need between 15 and 24 ounces, while riding mowers need 48-64 ounces.
When should the oil be changed?
For small mowers, it is usually only necessary to change the oil once every 50 hours or once per season. For riding mowers, it is recommended to change the oil every 100 hours.
