Amsoil is good stuff. Royal Purple is over-rated. When I get cheap I buy Havoline or Valvoline, both good quality oils.....I wonder where Advance auto parts oil would rank? lol
When did they start putting computers with internet access in the insane asylum. You have more than a couple bolts loose over there you filthy crumb bumb. Keep drinking that purple amsoil, it's going to be aallllllllright.
