is there an additive that is supposed to be added to the older LSDs? is it something still available from subaru or would any kind of LSD oil work?

 

also would running a synthetic oil mess with the LSD? you know with it more slippery maybe the clutches wouldn't grab as good.

I've used BG lsd addative along with royal purple synthetic gear oil and had great luck with it.

subaru makes a friction modifier for the older lsd's... the part number is 003304300 according to my haynes manual...

 

I picked up some Sta-Lube Equa-Torque instead because the local parts store had it...

so i hit subaru and talked to them and they said really there is no difference between theirs and what you can find in the parts stores.

 

i like guys like that, give you strait answers with no BS unlike some parts places.
