How good is AMSOIL compared to Mobil 1? I know everyone loves Mobil 1, but I won't use it again. AMSOIL is recommended to be changed every 25k miles or one year (non-turbocharged). For turbocharged, about 9k miles. With the high price of AMSOIL, it can be justified paying more for longer oil life.
Does anyone use it, has anyone used it? Did you like it/hate it?
