Does someone knows if amsoil injector oil (AIO) is jaso fc approved??Im trying to find witch oil is the best classified one for the less $$ possible. On the amsoil web site they recommend it in jaso application and in the spec of the oil its only classified as a tc-w3 oil...?? So is it or not jaso approved? Only the 100:1 and the 2000 series seems to jaso approved.

Castrol seems to have a new series of oils that are jaso approved and quite cheap too the "Go! snow" and "the R2" oils. Im Trying to make a list of oils and their classification to choose the best cheapest one... SWRules
