I have 5,000 miles on the car and am ready for an oil change. I changed it 4,000 miles ago with M1 10W30 and at 2,000 miles into that oil changed I drained a qt. out and put MMO in. It hasnt helped at all. So I was wondering what I should try next? My thoughts are maybe a heavy oil like 15W40 HDEO or would a lighter oil like 0W30 be better?
I was thinking I would use straight oil first and at 2,000 miles put a qt. of MMO in.
