    Whatever you use, make sure it's for LSD.

    Check what weight you are supposed to use in your transmission, and then find that weight with LSD additive.

    There are a lot of brands that folks recommend. Redline, GM Syncromesh, Penzoil, Mobil1.

    Tim, Quaifes don't use clutches, they're gear operated and you're specifically NOT supposed to put LSD additive in.


    In addition (edit for clarity)

    This is what Quaife sells, but from what I've read the requirement is any synthetic 75w90

    Actually, it says NOT to use ATF.

    What does ATF have to do with LSD additive?

    LSD additive is for clutch type LSDs, it makes the plates slip more to extend the life of the diff and smooth out the engaging/disengaging. Quaife and Peloquin are Automatic Torque Biasing differentials. There are not clutch plates, just planetary gear sets. You don't need to modify the friction of the fluid for use in an ATB, any gear oil (75w90 in Quaife's case) is all it takes.

    Essentially the ATB will not be affected by different oils as its function does not rely on friction (or lack of it). We always tell people to use the oil that is recommending for the gearbox (FWD) or non LSD axle (RWD) by the manufacturer, as it is more important for the gearbox or CWP to be protected than the diff.

    I would therefore agree by inference that one should not use ‘super slippy’ or LSD additives with the Quaife diff as if nothing else it won’t help the gearbox/CWP, but it could have an effect on the ATB’s function.

    Driving a FWD car, I come across the same kind of obstacles and it's always suspension set up. If the front wheels are planted the way they should the Quaife will do its job.

    Thanks,

    You posted a link, and said that it said specifically NOT to use LSD additive. But it didn't. All it said was NOT to use ATF.

    Supposed to be separate statements. I'll edit to make it more clear.

    also, from their site, this is all I could find on the subject.

    "the Quaife ATB helical gear limited slip differential is a direct replacement for the original factory ‘open’ unit and requires no special oils or servicing."

    So, in theory, he could use LSD additive gear oil with no problems.

    Yes, and you were 100% correct, except that "QUAF" doesn't make clutch LSDs, only ATB diffs.

    Meh. I haven't had to look into them enough to have that info on the top of my head. My car has an OEM LSD, with clutches.

    Either way, the gear oils I listed are all a solid choice.

    Redline MTL or Mobil 1 are your best option. I wouldn't use anything else (and don't).
