F Fedja Active Member Jul 8, 2013 #1 Service manual says I need 20W40 oil but I can't find any in local stores. Can I fill her with 15W50? It's 1997 Yamaha SR250. cheers, Ivan

Sonreir Oregon DTT SUPPORTER Jul 8, 2013 #2 Yup. That's what I'm using in my Seca (also calls for 20W-40). Covered a couple of thousand miles and no (new) issues.

AlphaDogChoppers Science is true whether you believe in it or not. Jul 8, 2013 #3 15W-50 has an even broader temperature range than 20W-40. It is a superior choice, IMO.
