Customer Ratings & Reviews

I started using Amsoil when I changed my rear differential gear oil, now that my transmission broke down and it was time to rebuilt it I went Amsoil again. When ahead and flushed my motor oil as well and refilled it with Amsoil as well.

I've been enjoying AMSOIL since day one of my first purchase!

This definitely helped improve fuel mileage and seems to help with transmission temperatures

Used this to partially change fluid in a 2006 Saturn Vue w Honda Transmission. Shifts smoother and better already.

great product shipped quick

Replaced my transfer case fluid, going from 2wd to 4wd is much smoother now.

Did a drain and fill on my transmission with Signature Series ATF. Fixed the rough shifts my 2018 Frontier was having.

Best transmission fluid out there.

So smooth shifting it makes my tranny crow, “Who says EV’s are quicker?”

Package is best ever, Have a 2015 GMC Canyon, no fill tube! I put a 4 Foot hose on snout and squeezed it in.

Initial fill on my 04 Silverado. No issues.

I take pretty good care of my vehicles and always used other full synthetics. I always wanted to try Amsoil but never pulled the trigger. Well, I’m so glad I ventured out. Great products, one stop shop, user friendly, and fast shipping. It came right to my door. I put their ATF in my Honda Ridgeline and it shifts super smooth. I also changed my oil and with their recommended products. All high quality stuff. Thanks Amsoil.

Been using Amsoil close to 20 years now. When the Signature Series came out that is all I use. Had my car for 0ver 20 years now. Not ever had any work done on the Transmission except for the routine maintenance with the fluid and filter changes. Amsoil SS ATF has been there along with Amsoil Filters when I could get them.

The product is great but the bottles leak. The box was soiled with oil when it arrived at my house.

This stuff is great! Flushed and filled 2 trucks with this product now and the transmission dramatically drives and shifts smoother, even got rid of a shudder i had in one

Flushed the factory toyota fluid out of my Tacoma 30,000 miles ago. Dropped the pan to change the filter and the fluid looked almost new. Topped off with fresh fluid and the shifts are better than new.

So I have a 2019 corvette z06 with the auto tranny. There’s a known issue with hard shifting due to the oem fluid being faulty. Let me say that after I did the fluid change I immediately noticed the difference no b.s! It fixed the hard 1-2 gear shift and runs smooth as silk now. I will continue to use amsoil products. Just purchased an oil change kit with the 0-40 motor oil and will be changing thag out asap!

I have used this fluid in all my vehicles and it continues to perform consistently well every time.

No sure if there's a better product for transfer case fluid change since the fill point is tucked up in the middle of your truck with about 17hundred and 4 things in the way.

Been using AMSOIL for years without a single issue thanks for continuing to offer the best products on the market
