I used this product on my rear deferential, and transfer case on my 2022 Toyota Rav4. It made a huge difference

I’m a big fan already. Let’s hope it continues to deliver

I couldn't believe how much more quiet my Tundra was after replacing the gear oil in both diffs and transfer case. I'm a long time believer in Amsoil, so the superior drivability was expected.

I truly like the ease of handling and clean dispensing of the gear oil. I also like Amsoil’s stand on protecting customer’s investments.

Put in everyone of my cars. I tow a lot and never had an issues.

I used the fluid recommended by Genesis to replace the OEM fluid in the LSD of my RWD 2019 G70 3.3t. Shortly after the replacement, the differential started to become very chatty, and there was some "resistance" during parking maneuvers, especially when it was cold. The shop added a tube of friction modifier, which improved things for 6 weeks, but then the chatter came back. After researching online, I found that some Kia Stinger and Genesis G70 had more success with the Amsoil Severe Gear fluid combined with a tube of Amsoil Slip Lock. I decided to try. It's been 2 weeks; so far, my LSD is as quiet as when my car was brand new, and I do not feel resistance

Best synthetic oil in the market. Used it for a 4runnur differentials/ transfer case

Of all the gear oils I have seen, this is definitely one of them.

the item leaked lost almost half of the gear oil

Chose this oil over GM factory oil since the GM part number was listed on the package. I like that it was the exact same viscosity so as to get the Amsoil quality as well as maintain fuel economy.

The product is superior. The time it took to get, however, is ridiculous. Ordered on December 16, 2024. It’s January 16th 2025 and I still haven’t received it. The first package that came in was missing the product. The second package never made it. The third package showed up with the wrong weight.

Your severe duty gear 75w90 was just the right lube for my front and rear differentials on my 2018 ford f150 4x4. I couldn't be any happier with it. Great stuff. I would recommend it to anyone.

I have used Amsoil 7590 gear oil in my differentials on my 2004 Dodge Dakota I feel less resistance coming from my differentials and seems to be working great no chattering I did add the limited slip differential additive with it because I read that in the Dakotas they need extra additive I know that the severe gear comes with it already in there but from what I've read it wasn't enough

Rear differential gear oil worked exactly as advertised. Easy pour and no mess. Limited slip diff perfect. Happy with customer

Gear oil worked exactly as advertised. Easy pour and no mess. Happy with customer

Love that the product is in the bags and that this product out last any other product out there!

The no mess pouch makes it easier to put the lube in the differential and everything feels smooth when driving.

This is the first time I bought gear oil from AmSoil. I got this for the rear in the Mrs F150, along with a new diff cover & lubelocker gasket. I made the rear practically bulletproof. Initial driving, we both feel a difference in pickup & acceleration & neither of us were expecting it. This is quality gear oil.

This is the only oil/ lube for the Tranfer case besides Engine oil that Amsoil has for the 3rd Generation Honda Pilot Touring/Elite 9 speed . I hope they come out with a Transmission 3.1 Honda Spec Transmission oil and Dual pump II Differential oil. That would be awesome 👌

Changed the PTU, Differential fluids and did a flush on the transmission shifts so much better now.
