Full Version: Swepco 201 in a 915 w/factory LSD?
What the best tranny oil for a 915 with a factory limited slip. I think it's currently Swepco 201 and I was going to use the same but not sure if there's any additives required for the LSD?

Not sure if this is correct but I use 50% Swep and 50% Mobil 1 7090 some thing gear oil and the Ford Limited Slip lub with a 80% locking factor
Guys at our local Porsche race prep shops say Swep is the way to go. Many of the cars they prep have 915's with LSD and TB diffs.

The best oil you can buy for a 915, 901, or 930 box! You are doing it right!
