Customer Ratings & Reviews

As a mechanic I have used AMSOIL products for many years with great results. AMSOIL Severe Gear 75w-110 is a great product, and is highly recommended. Only had one minor problem, one of the 6 quarts in my order, sprung a leak during shipping. Lost approximately a half a quart due to leaking bag.

Awesome product! The squeeze packs are easy to use.

Great stuff!

Nice price and will definitely get more later on

Great product fits the needs for 2014 and 2015 Ram 2500 and 3500 pick up trucks. Using the right grade of gear oil is a requirement for most newer vehicles. The squeeze bottle works best in tight area. I do own a hand pump but it takes long and makes more of a mess. My shop Country Tires &More is only using AMSOIL when it comes to power train fluids to keep vehicles running as long as possible.

Just like the bag says, Less Mess/Less Waste. I didn't have to get my gross fluid pump out for this! Saved a lot of time and hassle.

Amsoil is one of the few manufactures that make 75w-85. This is the recommended viscosity from Toyota. The squeeze bags work great.

Fast delivery , great product and staff service thanks AMSOIL

I've normally used AMS Severe Gear 75-90 in my differentials. Glad to see they now have 75-85. This was my first time using the pouch containers vs the bottles. I swear this the pouches saved me about 45 minutes in time. Super efficient and easy to use. I'll never go back to bottles.

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.
