Just bought a 901 transaxle with a Quaiffe LSD in it. Any recommendations for oil type and quantity for it. Don't want to burn it up.

The guys that do the early Boss 302 differentials for me always recommend original rear end mineral oil with the additive for LSD. I like simple.

Additive depends on manufacture and type of LSD. A Posi diff is a clutch package and most of those do need an additive that you can get at your FLAPS. However, the Porsche one may or may not need it, it really depends. |

However, the Porsche one may or may not need it, it really depends. So it looks like the Quaife doesn't need anything special in terms of oil, since it's gears and not clutch plates, and it looks like the 901 is rated to use 80w90 GL5 dino oil. So that's what I'll use for now. I may be racing the car with this transaxle behind a stock 1.8 liter L-Jet motor for a little while, but when I re-gear it for running behind my 215 Buick V8 with higher torque, Hp, and maybe higher rotational speeds, do you think the 80w90 GL5 dino will still be OK? |
