This is a great gear oil to use. This seems to work best for my sports car. It is a bit more than most but worth it.

Worth the money! Convenient because limited slip additive is pre-mixed.

I have used this product in the rear differential of my 2003 F150 4x4 with great results. This is the second time I have changed the gear oil with this product and I like it better than other synthetic gear oils, primarily because I experienced no chatter with it (I did add the Ford friction modifier). I also use this same brand for the gear oil in the front differential as well.

ゲトラグミッションのオーバーホール後に継続して使用していているがやはりロイヤルパープルが今までのギアオイルの中でも1番良いと思う。追記 シンクロマックスやその他ブランドのレーシングATFも熱が入る前からスコスコと入りフィーリングは良いのだが熱が入った後はどうしても柔らかさ故の金属同士の接触感が感じられるので温まった後のフィーリングを考えるとマックスギアが安心感があり温まるまでは意識的に優しくじんわりシフトすればゲトラグ特有の あの感じ は大した問題では無い。

I'm so used to companies flat out falsely advertising their products and promoting product features that don't do as described.. I've gotten to the point I just don't believe anything and only expect what I've already come to know from experience.Regardless, the time came to change differential fluid.. and I want nothing cheap for my Ram. I decided that, based on reviews, the least this product would do is lube as well as other gear oils.To my surprise, there really was immediate results from using. I expected nothing noticeable, but it actually did improve performance. Most people I know never even bother changing their differential fluid.For a 100 mile round trip (that I make twice a week, every week for years).. my MPG increased from an average of 14.5 to 16 on average (fluctuates with oil life, air filter and aggressiveness) to 18.6, which is actually higher than manufacturer's estimated MPG 14/18 city/highway). I gained this while driving fairly aggressively (a bit above normal), as gas mileage was the last thing on my mind to test or check. I just happened to notice after the trip while checking diagnostic logs for other things.The gain was just significant enough that it was undoubtedly the fluid change affecting it. Too many things affect torque and horsepower for me to have solid statistics from comparison, but as a "first time" Royal Purple user, the results that have been noticeable has made me more optimistic towards effects less noticeable or not noticeable at all.. such as advanced conditioning and wear reduction.. effects that would take much more time to observe.Because of my experience, I will now be ditching Mopar and replacing various fluids throughout my vehicle with Royal Purple.I don't recommend for others to make decisions based on my review, though. I suggest trying the product out next oil change and make decisions based on first hand experience.

I own a 2004 Ford F150 4x4. While the truck only has 40000 miles on it, I felt it was time to replace all of the fluids. Seeing Royal Purple used on several TV shows, I decided to give it a shot and replace all my truck's fluids with RP products. As a sidenote, my truck's limited-slip rear end has chattered when taking off or accelerating around a corner for several years. When I finally took it to the Ford dealer a year ago, they said they could put some "anti-friction" additive in it to fix it. Unfortunately, it didn't work. So, fast-forward to this weekend when I changed the rear differential fluid over to RP 75W-140 Max Gear lube. Lo and behold on the first test drive, there was no chatter whatsoever! The truck seems to be smoother driving as well, but that just may be my way of justifying the expense. Haven't completed the swap of all fluids, but will be interested to see the overall change in my truck and a hopeful increase to the gas mileage. Without a doubt, I will always recommend RP to my friends and family based on this experience!
