Customer Ratings & Reviews

My order never arrived so I contacted customer services and I had it 2 days later!! Thank you, we’ll done!

It's the best oil and atf I have ever used. I'm so glad I made the change and haven't regretted it for one second.

As with all of the Amsoil products this stuff is good stuff

I am a firm believer in using top quality and test proven products . Amsoil signature ATF has kept my vehicles running trouble free and I would not even think of using another ATF based on my years of experience using Amsoil. Blunt, the best!

Can't go wrong with any amsoil product

Haven’t driven with new fluid long enough for thorough review. However, initial impressions are good. I simply trust Amsoil for all my fluid needs.

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.
