Originally posted by TooSlick: Most of the Amsoil formulations are now rated ACEA "A3/B4", or ACEA "A3/B3". This includes the 0w-30, 10w-30, 10w-40 and Series 3000, 5w-30, which is primarily formulated for diesel applications.

Originally posted by Dr. T: OTC A3 in U.S.: Mobil 1: 0-40 and 15-50 only Castrol Syntec: 0-30, 10-40, 5-50 and 20-50 Quaker State: 10-30, 5-50 Valvoline SynPower: 5-40 and 20-50 only Does Pennzoil have a 5-50 Synthetic? If so, it too would probably qualify...
quote:Well, that makes me wonder about Schaeffer's claims regarding ANY spec their oils meet. It's IMPOSSIBLE for an oil to be both A3 and A5 since A3 calls for HT/HS of >3.5, and A5 calls for HT/HS of <3.5.
