    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?

    Is it better than Mobil 1 75W90 LS?
