MAX GEAR 75W140- Quart, pack of 6

Used as the heavy duty option for my 20’ Jeep Gladiator. Arrived and worked exactly as expected.

I love Royal Purple Differential Fluid as well as their Manual Transmission Fluid. Good stuff that I swear by!

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.

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.

Royal Purple is always high quality.

Great price and fast shipping

Good product use it in a Jeep unlimited Rubicon with 4.88 gear. Use the 75-140 in the rear and 75-90 in front. Web description is misleading saying pac of 6 ...... only one quart arrived.

Suggested for the ford 8.8 rear differential in the 01 explorer sport trac even tho amazon says no. Really smooth and kinda messy. Make sure you have a small flex funnel to add the oil. No leaks yet but that has to do with seals not fluid. Seems hugh quality uoud expect from royal purples.

Buen producto, ademas ya viene con el modificador de fricción, por la tanto te ahorra esa parte. Lo use en un mustang gt

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。

Buon prodotto come tutti i prodotti royal purple laia marca preferita quando si tratta di automobili

Perfect and a pretty colour

Luv this stuff for my 2014 RZR transmission.
