Transmission and Transfert case Oil

Here is a very good paper on which oil should we use in our classic car. I took it from www.thecj2apage.com discussion forum.

Transaxle_oil

At the end of the paper, it summarize a couple of brand:

Amsoil Synthetic manual Transmission and Transaxle Gear Lube 75W-90 GL-4
Citgo Citgear Standard XD 75W-90 GL-4
Pennzoil Gearplus 80W-90 GL-4
Pennzoil Synthetic 75W-90 GL-4 (from the spec sheet, the best overall viscosity curve)
Quaker State Multi-purpose Gear Lubricant 80W-90 GL-4

Enjoy it!
