Customer Ratings & Reviews

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.

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.

Great oil products at very good price

This fluid worked great.
