    Would this be better than the 80-90 Castrol? Thanks

    For all the fellas using whatnot brand X in their T-cases:

    What I can’t figure out, is that if the barnyard version 75W90 gear oil is fine in the T-case, why they heck does Toyota ship these cans of fluid all the way from Japan? It literally has a picture of a transfer case on it, and is called Transfer Gear oil, and is packaged in a non-volatile tin can (has no plastic to react with its contents). I live in Canada, and sure enough, the dealer stocks this fluid imported from Japan.

    The transfer case has a large, multilink, chain in it, and one bronze synchronizer. In essence, it is different than a basic gear set, like your rear diff, or front diff. I am not sure why it would be worth it, for the cost of a single bottle/can of oil, changed hardly ever, not to use the Toyota LF fluid unless you simply cannot find it or afford it.

    I dunno. My T-case certainly has given me no grief since I went back to it from using synthetic 75W90.

    The t case wants 1.1 liters so that means you have to buy 2 just so use a little bit of the second can.

    I put in one can and it filled it absolutely perfectly. Came running back out the fill plug on level ground.

    oh wow. Ok then I might get one. The cans here in Lebanon are 60 dollars a liter. What did you use to get the oil in the t case? A pump ?

    Yeah.
    The Ravenol lists the Toyota P/N for the Toyota LF 75W fluid and is significantly cheaper. I haven't done mine yet, but that is what I will be using.

    Funny thing though when looking at the entire toyota transfer case fluid part#, the ravenol compatibility listing for their toyota''s part #'s don't quite match up....last digit in their part# is a 0 while toyota's is a 1. Don't know if just a misprint or they did it on purpose because its not quite the same stuff.

    I think there's a European number and N. American number.
    Ravenol matches the European number.

    Do you get these free or at a discount? That will great in the t-case... it's not cheap, either. Probably work well in the axles, too.

    Yeah.
    They actually list both numbers on the Ravenol bottle, and found this on the interwebs:

    "Replacement and equivalent to Toyota center transfer case fluid part numbers 08885-81080 US spec and 08885-81081 Euro spec."

    Pretty sure both those Toyota part numbers are the same stuff.

    6 dollars a quart. It’s good stuff you think?

    Yes, it's a PAO synthetic with a high VI and low pour point.

    Awesome. Thanks.

    should I put it in all 3 or just the t case?

    I already used the 80/90 stuff a month ago in all 3

    75w LF is $88.38 from my dealer. It is what it is I guess.

    Toyota LF has quite the additive package. I would not use anything but that.
