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.

I typically do most of my own maintenance, but due to time constraints, I had my mechanic change the oil in the rear differential on my 2008 GMC 2500 HD truck. The truck is used as a daily driver plus towing my 10,000 lb. travel trailer. This is the second oil change. When I picked up the truck, the mechanic said "Wow, that Amsoil is amazing - the old oil looked great - hard to believe after 100,000 miles." He volunteered the response, I did not ask.

I used Severe Gear in my FJ, 3/4 ton Suburban and two Porsche track cars. It is the best gear oil out there. I use Amsoil Slip Lock with Severe Gear for perfect, noise free operation of a limited Slip in the track car. Works great.

I haven't had any issue and all gears have been working good.

I had got it to replace the old diff oil in both differentials in my 2002 Chevy Blazer LS, it works great, it accelerates smoother/ faster than the old oil, and it the vehicle had over 200,000 miles on it when I changed it, now it has over 201000 miles on it and it's still doing great!

I run this is my mini quads transmissions. It holds up better than anything else we have found. Always looks good and we seem to get longer life than the rest of the racers.

Had the oil in the diff previously and came out slightly worn looking. 70k miles. Never had any issues so far with the Limited Slip Diff locking up. Using AMSOil transfer tubes worked well also. Just had the car on ramps.
