I have a Billy Goat leaf vac and about to change oil and spark plug. What type of oil should I use?
And I thought this was the only billy goat vac around, have fed it many times
I think most air cooled motors spec a 30 weight straight grade oil, but most of those I've found are non detergent for those "vintage" engines. You're probably OK with 10W30 regular engine oil or maybe 20W50 in the summer. What kind of engine does it have?
