I'd like to get members opinion on the various manufacturers Gear oil. Which did you use?
mobil 1 75W-90
Redline
Royal purple
Amsoil Severe gear
also. if you used a additive in addition to whats in the lube
I used RPM transmissions recommendation:
We recommend Valvoline full synthetic 75/90 (we do not recommend the GM gear oil, Redline, or any shock proof gear oil) • Use 1 tube of GM limited slip additive part # 1052358 unless unit is a Stage IV with a Quaife or Wavetrack LSD. •
Redline, with no additive, for the last 18 years......
EDIT: let me clarify that, a little. I have changed the lube a couple of times, in 18 years. I initially changed the diff and tranny lubes, when the car was a year old, and at that time, refilled them with Redline fluids, and have used Redline ever since.
