    I'm just past 30K on the odometer and I am about to pull the plug on the rear differential. I usually like to use the exact fluid that Toyota specs, but it's really expensive. Red Line advertises a 75W85 fluid that meets the Toyota spec.

    I have read numerous stories from owners stating the great importance of sticking with the correct spec oil for our differentials...so I am not at all comfortable with putting in a standard 75W90 off the shelf.

    Any users of the Red Line fluid on the Gen 3? If so, how is it working for you?

    Thanks in advance for your feedback.

    Does it seem to perform as well as with the factory fluid?

    To be honest, i have no idea if it made a diff or not. I did it for long term protection of the diff.

    I hit 60k and swapped out diff fluid. Oem fluid was almost new looking. I used 75/90 amsoil severe gear.so far the trucks feels like it has less rolling resistance.

    I’m about to tackle this as well. Diffs from what I have read here 75 w90 is fine. Dealer uses it from my quote from them. The transfer case is the one you have to stick to spec. This site is great for us best truck in the market owners. That redline isn’t cheap. So must be good

    I'm using the Redline 75w90 in my 4runner. Works great.

    I'm using Royal Purple Synchromax trans oil in my transfer case - it's a direct replacement for Toyota OEM.

    you don’t need the LS unless you have a limited slip. Tundras do not come with those from the factory.

    Using Amsoil 75w-90 in my diffs and Ravenol 75w MT3 in trans case. Truck still running like a top and the transfer case seems to shift in and out of 4WD faster and smoother. Before I had a noticeable thud.

    All my diff fluids came out looking OK at best. Glad I changed them out when I did. Transfer case fluid looked new still @77k miles.

    Wally world Full Synth 75-140 has worked for me for 323,987 Zero trouble miles so far in both diffs and TC.

    I was a bit proactive with changing both diffs and the transfer case fluids at 25,000 miles last summer in my 2015 SR5.
    Stuck to the factory specs for weights.
    Used Ravenol for the transfer case and Red Line for the front and rear diff
    Handy chart for anyone who needs it.

    Dealers dont even use the fancy stuff. The 75w-90 off the shelf is perfectly fine. The only time they use the specific high dollar stuff is warranty cases.
