Royal Purple Max-Gear 75W90

[Jfcroni]

Can we use Royal Purple Max-Gear 75/W90 Synthetic in our Rocket Final Drives.

The oil is API GL-5 and has an additive for EP situations.

Mobilube SHC 75W90 is unobtainium…it seems.

What are you guys using?

Don't know why not. I use Amsoil Severe Gear 75-90

What kind of lube are you using on the splines?
