          Used for front and rear differentials in my 2001 GMC2500HD. Have had it in for about a week now and its doing good. Purchased Royal Purple over M1 due to a few reviews I saw plus a piece on a truck show. Vehicle they put it in saw an average of +7hp and +6ft-lb of power at rear wheels. Less parrasitic loss in differentials due to fluid. Hope to see the improvements in my truck. Awesome product!!

                Royal Purple quality is practically legendary as is, that is why I chose this gear oil. I was very happy to find out it was already formulated for positrac and I didn't have to buy anything else. I do a lot of hard core off roading, and this is what everyone around the pits agrees is the best.

                  It is a great brand, may be paying a bit for the price. Use in a transaxle is difficult to fill, use a special funnel/pump. My main issue I have with the color is that it is hard to tell if it is getting dirty quickly. Though the quality is very good for the price vs. AMSoil. Best for the price, and there is a noticeable change in shifting with my car now, less metal shavings/fragments left in the fluid vs. other products. Just my 2cents.

                        I got this because my other favorite brand isn't recommended for use in Harley transmissions.
                        The Royal Purple is compatible with yellow metals which means it won't corrode any brass or bronze components in your tranny or differential.
                        I don't know how much or any yellow metal is in my tranny but better safe than sorry.
                        I also like that it's easy to see on the dipstick when it's new due to the purple color,
                        The tranny shifts smooth and runs great.

                            I'm glad to be of assistance! We have not received any negative feedback from any owners of GM vehicles using the Eaton G80 locking differential, indicating that the use of Royal Purple Max Gear 75W-90 (part #01300, quart bottle) in those differentials had caused any issues from the friction modifier that we include in the product. Max Gear is our normal recommendation and it works great. However, if you absolutely prefer a Royal Purple gear lube that does not include an LSD-FM (limited slip differential friction modifier) at all, I need you to provide your vehicle's year, make, model and engine size so we can assist you further.

                            make sure to check the specifications of your trans. and match it up with that, you never know if you need 80w-90 (doubt full) it is very good product and will help any system.
