yeah amsoil kicks arse. might switch to amsoil oil and filters once i run out of mobil 1 tri-syn. 25000 miles or 12 months, whichever comes first. haha.

another hot topic is what's a "true" synthetic. castrol doesn't use a "true" basestock and neither does mobil 1 anymore after losing a courty decision to castrol. so what are the "real" synthetics out there? amsoil, royal purple, neo, valvoline synpower, and chevron supreme syn.
