I have 10w-30 castrol oil. Can i put it in my 5 hp briggs and stratton engine
10w30 is the factory spec.i put generic 5w-30 car oil in my honda gx160...
Not quite.pretty much oil is oil, provided it is for engines.

howza-bout some 85w-90? that'd work, right? its oil for gears, and there are gears in the engine!
lol
I pack my crankcase with grease![]()
