Answer 1

If it's a two-stroke, you mix two-stoke oil in with the gasoline. If it's 4-stroke (has a little oil reservoir), any 30-weight motor oil will do.

A straight 30w motor oil for a straight gas mower(4 stroke).If it is a 2 stroke(mix oil with gas) then you need 2 stroke oil.

SAE 30, consult the owners manual if you have it, it may require synthetic oil.
