Customer Ratings & Reviews

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!!

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

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.

I bought 75w-90 for my rear differential and front ptu I've already changed the rear differential gear oil and it has quieted the rear noise i was having i changed it at 52000 miles and happy i did this gear oul is much better then the oem ill be changing the front ptu soon as weather allows id definitely recommend this product to others as it high quality and exceeds the owm gear oil

Great packaging makes it easy to fill the front and rear differential cases on my truck

Easy to use and quality product.

I have used Amsoil off and on for years and have come to the conclusion that from now on there will not be any other product that will be used in my vehicles. Now there is no excuse for not using the best. Their customer service, product selection and lightning quick delivery is second to none. I have trusted the quality of their products and know that my vehicles are better off.
