Customer Ratings & Reviews

live in Las Vegas where the heat is excessive, this oil for me is the best, my transmission is the 6L80 of a 2019 Chevrolet Suburban, since I put in this oil the transmission feels different, the best of the best.

I have been using Amsoil products for years now since a friend from work recommended them and got me started on trying the Severe Gear and Engine Oil. After really being happy with the Sever Gear and Oil results, especially the Metric Motorcycle Oil, I decided to start servicing my Hyundai SUV's with the Signature Fuel Efficient ATF. After many successful miles later I now put it in all of my transmissions. The latest being my 6L90, which are known for heat and reliability issues. Truck transmission shifts and operates very nicely even at the higher temps that these transmissions operate at. Fluid has held up very well, just like I would expect from an Amsoil product of any kind.

Very good product, great packaging, fast shipping, Thank you

I ordered enough fluid to do a transmission service. I was disappointed that one of the quarts was leaking. You would think the soft containers would not be as susceptible to being popped open. With that aside the product (fluids)is top tier.

Put it in the truck and don't worry, it will do it's job.

After much searching to find the right fluid for my transfer case, I found Amsoil synthetic of the right grade. It was so easy to use, there just isn’t room to get a hard bottle higher than the fill hole.

Amsoil Signature synthetic ATF lowered the operating temp of the transmission in my 2016 Silverado.

I replaced my original fluid at the 40k interval with great results. Runs smooth and would recommend for a transmission fluid upgrade.

Just put this in my 2011 Ram 68RFE, shits so smooth now.

👍

My 2016 GMC Yukon Denali started shuttering at 57k miles and it’s been perfect since and just did a dump and fill at 155k so I know this stuff works and it’s the best trans fluid there is in my book

Used this on my old Honda pilot with 200k it cleared up stubborn and hard shifting easy to use and survived hard towing would recommend.

I know… warranty intact. But if the OEM says it failed due to the fluid, you may be out of a vehicle for months while everything plays out. Even if amsoil says it’s ok, do not go over OEM specs if under an extended warranty.

Love this stuff smells like liquid snozzberries and horsepower. Real talk this is Mary K for men. I buy amsoil she gets ditzy broad stuff.

Very happy with this product

Great fluid. Light years better than factory fill junk. Buy it, run it! You won’t regret it.

After researching many different fluids for my 2019 Camaro ZL1 automatic transmission, I settled on this one from Amsoil. I must say now that I’m very happy with my choice. After thoroughly testing it out on a 1,100 mile trip which included 3 hard days running at Tail of The Dragon I was amazed at how well the trans temps stayed down. After my hardest run and fastest run on the Tail the trans temps stayed down was only 190 degrees! I’m convinced Amsoil was the right choice!

Topnotch fluids. Can't go wrong with AMSOIL. Quality can't be beat.

I run this in my car and it shifts smoothly and haven’t had any issues
