Transaxle oil for 901 With Quaiffe LSD, Just bought one. Options

[motorvated]

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.

Dr I think you have opened up more than one 901 over the years and would know what works in them. (IMG:style_emoticons/default/biggrin.gif)

The 901 with the ZF LSD literature specked a different Shell gear oil than the regular 901 with out LSD.
The Sport Purposes docs show Shell S1747A (USA Shell Gear Oil 90 E.P.)
Original 901 boxes that came from the factory even had a little aluminum tag on them showing the the Shell SD 1747 A.
Maybe had some LSD additive like most disc LSD of the day.
Do you have any info on this Shell oil?

Dude, that pic and info rocks! I forgot what was supposed to be in the LSD type, but last time I checked I found that info....and forgot it because it was like 2005. Lately, I have been doing a lot of LSD....er, LSD work. Old 1968, a 915, another 914, another 915.....I actually HATE doing LSD work as it always ends up being more work. I feel like a whore that keeps getting fat nasty guys, but has to go with it because she has to pay the bills. Ah well, its nice to be useful.
