Customer Ratings & Reviews

It only makes sense and just a few dollars more to get the best performance and protection for your vehicle.

Put this in my 2015 camaro ss dif. It seems to work so far

I had some significant noise coming from my driveline, I have a 2016 Ram 1500 4x4 and figured it had to be the differentials, it was, used the severe gear and noise gone. Very quite ride now. I pull a compact tractor frequently to severe gear was the way to go.

Quality product, stellar reputation, easy to use!

Love the squeeze containers, convenient, fast, and clean fluid change. Peace of mind knowing I won’t have to do it again for a while with the Amsoil fluid.

Running this on all my trucks for over 200000 miles on heavy duty towing,, very minimal wear on my differentials. Extremely recommended!!

Great product easy to use.

Used for Transfer case and Rear Differential on a 2019 Rav4 adventure model. It's been installed 2 weeks now and driven 1,000 miles. There is no loud noises and it's still running, so that's a good thing. Any difference?, none I can see. It will be when I change it out again to see if any changes in the color or smell. As for the soft packs, I should have got the quart bottle. I use a pump to fill the cases back up and this was not working, guess it could be my pump, but I filled a container and was able to pump out of that. Anyways, this is supposed to be great stuff, we will see.

The bags made the job super easy!

Severe gear in diff on Challenger R/T, definitely smoother and quieter. OE gear oil looked like metallic paint at only 4,000 miles

I like the review on the oil

Great product and functions excellent in my Ram 1500

packaging is perfect to use when filling the diff on my truck

bag isn't as easy to use as i thought it would be i will buy bottles next time

Chevy 1/2 ton 300.000 plus working like a charm

Great stuff, Would use nothing less! Had a minor issue with shipping last order. Called and issue resolved quickly. Great communication, and outstanding customer service! Very hard to find in a business today! Thankyou Amsoil!

Been using this oil for almost 20 years. Never an issue.

Been using nothing but AMSOIL products for my vehicle and I must say very impressed and happy with my purchase I believe I’m all their products and so should you to protect your vehicles. I just recently bought this gear oil and I love it.

AMSOIL reminds me when there’s gas station/big box store / cheap alternatives geared towards profit not production AMSOIL has the products I want to make my vehicle last, thankyou kindly

I've been using Amsoil Severe Gear for years in all my equipment including my previous HTM 850 HP Boat. I used 75W-110 in my Bravo 1 OD and never had a problem. Sure you can find various brands of synthetic oil going to chain stores or auto parts stores but none offer the proven protection of Amsoil products IMHO.
