newb to research Amsoil and to show him that through research ( along with my humble, :), opinion ) that Mobil 1 is shit. Err maybe I should have said crap as my last "M1 is shit" comment was deleted, but the moderater's explanation was to watch the SUBJECT profanity. So maybe its ok. Again, Mobil 1 is shit, and if you dont believe me, just test it for yourself against Amsoil as I did.
