Hello fellow tribologists. I was wondering if anyone has had experiences(either good or bad) with mobil 1000 dino? It was on sale at the local Canadian Tire so I bought a jug for my latest change.Grade was 10w30. Owners manual says 10w30 ok for O deg.F.and above.Driving a 2009 Accent 1.6l. The engine is noticeably quieter with this grade than the 5w20. Thanks for your input.
