I use AMSOIL for everything because AMSOIL is what is called a Reference oil. An oil that all other oil Mfr's aspire to be like. A bench-mark oil. Would not, could not use anything else!!!

My front and rear diffs love this stuff !! Temps dropped considerably after swapping to this !!

Use this amazing gl5 gear oil from the diffs in my duramax to the diffs in my 600whp Mitsubishi Evo. They are always ready for the challenge!

I use this in my 2014 Harley-Davidson Motorcycle. The transmission shifts smoother and runs quieter. I also use the 20-50 Synthetic in the crankcase, where I notice smoother operation and lower temperatures.

I am using this in my truck and my SUV, it work great

I know Amsoil is the best. Anything with Amsoil in it will live its intended lifespan.

Always performs well and has protected my gears for literally hundreds of thousands of miles with never a failure.

Best gear oil for my outboard

I own a 2002 4 wheel Drive Chevy Tahoe. I'm a Tournament Fisherman, and I use my Tahoe to tow Thousands of Miles every year. I have Always used AMSOIL Series 3,000 5W/30 in the engine, and also use AMSIOL Severe Gear 75/90 in Both Front and Rear Differentials Without ever having any driveline Problems with my 14 year old Chevy.

Put this in my 1995 Corvette differential with limited-slip clutch packs. 10,000 miles so far and no issues. I purchased the AMSOIL synthetic product for its superior quality and long service life... will last longer and protect my vehicle better than conventional, so in the long run it's definitely worth the added cost.

Used this in my air cooled 911 trans. Much more smooth shifting.

Used this product first time together with Slip Lock Gear Oil Additive. Noise and temperature dropped.

I just used this product in the transfer case and front and rear differentials of an AWD Infinity.

Great rear end oil for drag racing rear ends

Run this in 3 trucks in both the front and rear diffs. One of those also runs it in the transfer case (NP205). Have had zero issues and have noticed less wear during yearly inspections. No fault of the gear oil at all but you need to make sure all your seals are in good working condition as this will let you know if it they are not, much more so then normal conventional gear lube, at least in my experience. Via an external temp reading (infared gun) of the diff cover after same trips with same load have noticed a drop in temperatures as well. Basically it works, and is the only thing I will run in high abuse applications.

I've been having issues with my 3.73 gears, after taking my car to the track the gears whine and it can become annoying. Since I've been using Amsoil's 75W-140 for the diff, the gear whine has gone down a bit. The car feels great and my Torsen Limited Slip Diff seems to be behaving very well with the new oil. I recommend this product.

Use in a ford f150 as required. Change around every 60, 000 miles. May not be necessary, but can't hurt to have clean oil. Decided to use Amsoil after reading an independent test/study on gear lubes by a major oil company. Many oils were good. But Amsoil outperformed the other oils in nearly all of the tests performed. In 1998 when I first changed the oil Amsoil was all I could get in synthetic 75w-140. Ford dealers didn't carry it and the service manager recommended using 90w, stated, "We use 90w". I said, "the diff. Tag states 75w-140! You don't sell the oil you recommend?". Wonder how may diff's ford burned up? Have used Amsoil since then.

Used in a off road truck. no failures, change every 30,000 miles and is still clear as a bell.

Used gear lube in transfer case in 2013 Acura RDX AWD. Working great.

My new F-150 only has 15k on it now and I still haven't changed the front axle but I did switch the rear over to 75-140 at 10k. Had a ford ranger that I bought new and switch it's rear to amsoil at about the same mileage. I used it for my lawn service runner. It was over loaded it's whole life up until 102,000 when I was hit and they totaled it. I sold that rearend to another guy that was going to rebuild it with a spool and deeper gears. He called me back and said it looked like brand new inside. Pretty amazing considering what that truck went through.
