Royal PurpleMAX GEAR 75W140 Quart BOTLE

Used in my 2013 Ford escape 2.0 differential no issues. Original oil has about 160k on it and was black thick and stunk bad.This seems.to work great no issues at all.When I bought it a year ago it.was $10ish cheaper

Good fluid and a good price!

I have been using Royal purple for years. I've used it in atv, utvs, cars, SUVs, RVs, it's the best. A little more expensive but you can't buy better oil. Their filters are great 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.

Exactly how described and expected

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 just changed the fluid in my 2006 Dodge Magnum 5.7 hemi. I put the car just in case someone is wondering whether this will work. Well, it works, and it works great. First of all, the car is quieter upon start-up. Secondly, the car is faster now because it maintains higher RPM's longer before shifting.I would recommend after changing to let the car run and to drive it like grandma for about 10 miles or so just to make sure the gears are lubed completely before you get on it. I'm so happy with it I'm going to change the lube from the factory stuff in my other cars!

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.
