    Ok all I have been doing a bit or reading up on what fluids to use on the diff's and transfer case on my 2016 Tacoma TRD sport.
    Front and rear Diffs call for LT 75W-85 GL-5 not a readily available fluid, so after reading up on the same questions from fellow Tacoma owners in this group have opted for the Mobil 1 75W-90 (Limited Slip Fluid) and changed it at 30K miles. So far all good as expected.
    Now comes the Transfer case it calls for SAE 75W LF, I have asked the dealer and they wont tell me what it is and also said Toyota only fluids...BS... What has everyone else used? Any issues if you use the Mobil 1 75W 90 and do you still need the Limited slip fluid? OR stick with the over priced Toyota stuff.
    Thanks guys
    Kev

    I use Redline MT90 in both my MT and transfer case; should be able to use it in a 3rd gen transfer case as well.

    You can use readily available 80W90 in the front and rear diffs. I use Valvoline synthetic 75W90 because I can get it cheap when it's on sale.

    I've had the Ravenol 75W in my t-case for about 9k miles now. No apparent difference from OEM fluid, everything shifts smooth into 4wd and back.

    I changed it at 30k miles, but was likely not needed. Fluid that came out looked practically new, I didn't have it analyzed tho.

    I was about to post something similar. This is my first time doing the diff and transfer on any of my vehicles. Looks super easy, where do you guys buy your oils for these changes from? I feel like the stealership will rip us off.

    Get 1L of the Ravenol and any 75W90 for the front and rear diffs

    Cheaper if you buy on Amazon or ebay then going to an auto parts store including drain plug gaskets. I did mine at 5k just for insurance and replaced with redline. My MT psychologically shifts easier :)

    Visit a few Toyota dealers and ask them what oil they use for the transfer case. The transfer case only requires about 1.2 Qt so I would just buy four QTs of Toyota SAE 75W LF then use it for 3 changes. I think most Toyota dealers use no name brand 75W-90 oil. I just don't know about using Ravenol - Read some reviews from BTOG forum.

    The Toyota 75W oil is approximately $60.00 a liter online.
    The Ravenol 75W will work fine. Ravenol oils are very good.

    Anyone try Amsoil Severe gear for the diff's? I was looking into to changing mine soon and currently doing some research on it.

    Have many of you guys ordered your supplies from oempartsource.com? Wanted to know if their website is legit/reliable, their prices seem pretty good.

    Why not just order the correct Toyota fluid through a dealership?
