I use this in the rear gears of my Ram truck It keeps the gears quite

Good stuff

I was reading a review on changing differential oil on a Toyota 4Runner. Guy said he switched all the fluids to Amsoil. I decided to check it out, located the website and ordered this fluid. Looks like great stuff. I was also impressed with the speed of delivery, just a day or two. My vehicles will be using Amsoil oil from here on out.

Run this in my sons truck and all is well.

this is the second vehicle I switched to Amsoil gear lube. the first was a 2018 Nissan Frontier, this vehicle is a 2014 Jeep Wrangler. Can'tsay enough good things about the product. Easy to work with, saw an instant increase in gas milage and power.

Great oil and easy to use.

This is great packaging ,saved a great amount of time filling front differential . Oh and the oil is as usual the best to use !!!!!!

Had used your products in my motorcycles forever, and never had an oil related issue. Wouldn't use anything else. Now that I'm retired, I traded the bikes for a golf cart, and still using Amsoil exclusively. Nothing better. Thanks

Excellent viscosity ratings, easy to fill the rear end with the squeezable container. SIncerely Robert

Easy to use, high quality, and easy clean up after the obligatory mess

Just put it in my differential so I don’t know how it will work long term. I do like the packaging Amsoil uses for their gear oil

Bought a '88 iroc and wanted to start the process of changing the fluids to the best I could get. Love the package.

I have one particular customer who was so impressed! To this day he still raves about the difference this gear oil made in his vehicle.

I purchased this to put in my brush hog gear case. What a difference! The stock oil would vent out, and the gear case would be hot to the touch after using for an hour or so. Once I put the Amsoil severe gear in, I brush hogged for 8 hours, and you could hold your hand on the gear case. That is amazing!

Amsoil member for years. Great product.

Gears and bearings run cooler,quieter and smoother. It stops almost all friction and stress on gear surfaces also dissolves sludge and varnish from old lube.

Use only amsoil products in all my vehicles and tractor's.

I flushed the rear differential fluid for a friend, and he immediately noticed how smoothly the Amsoil gear lube flowed compared to petroleum-based gear lube. The physical properties of the signature series lubricants are far superior to petroleum based. Note: Recommend not using "Severe Service" gear lube in manual transmissions as it may interfere with proper function of the synchronizers. For manual transmission, regular Signature series gear lube should work superbly. (Fyi, I'm an experimental physicist, and have been using Amsoil products for over 40 years.)

The AMSOIL SEVERE GEAR® 80W-90 was the perfect synthetic product for my 2002 Tundra’s rear limited slip differential. I did some heavy towing on a 1,600 mile trip with no problems.
