AMSOIL

Amsoil ATF Amsoil ATF is the number one transmission fluid I recommend running in the F/W4A33 transmissions. It surpasses the ATF+4 and SP-III spec's by a long shot, and will keep your valvebody and clutch packs happy for many hard miles.

Amsoil Amsoil makes some of the best oil out there.. period. The Dominator series works awesome in the 4G63 because of its high zinc content. This is what keeps the rings from wearing under extreme conditions, as well keeps the turbo bearings looking new. Don't just take my word for it though, Forced Performance did an extensive write up between different oils HERE. Notice every recommended oil except Amsoil Dominator said high zinc/phosphorous.. Dominator, on the other hand, received a "heavily fortified with zinc and phosporus" mark. In the long run it's a little cheaper to spend a little extra each oil change than replacing the turbo or building a new motor!

 

If you would like something else Amsoil sells besides what's listed, I can still get my commision (which goes towards paying for this website) off any item they sell. Just check out their Online Store.
