matt,
I haven't had any experience with amsol oil. However,I do know abut Mobil 1. I have used it my 1993 chevy blazer exclusively. Never had an engine problem, only tune-ups. After 150,000 miles my mechanic says it runs like new. Now he is sold on Mobil 1. With results like I've gotten I wouldn't say Mobil 1 is overpriced.
