Customer Ratings & Reviews

I use this to service 2009 Toyota Tacoma for a drain and fill once a year. About 3.5 qts per service; far and away better than WS. Shifter feel is always right on, thanks for a quality product!

This ATF is the best!

I run all Amsoil fluids and oils in my 2025 RAM RHO. The truck runs smooth and quite.

Works awesome

AMSOIL Synthetic AT Fluid has superceded my expections and I plan to continue using it in the future on my vehicles!

Can notice a big difference in shifts from factory oil to Amsoil. Just runs better and with over 334,000 on my LMM Duramax…that is all I will use. Swapping my 26 LP5 3500 over in the near future.

I like that this stuff is an alternative to AutoTrak II.

Good alternative to the signature series. The preferred price is a good value.

Hi As you all know, this product is top shelf! Nothing more needs to be said!

Use this fluid in the trans and transfer case. Fluids changed every 30-35,000. Trans is always spotless with no signs of wear or tear. 94,000 miles and still smooth as day we bought it

This product is amazing will keep using this product

This is great fluid to use over factory for normal everyday use. The testing proves it. But if you are in extreme climates or tow alot then step up the signature series for additional protection

Exactly what was required for my truck. Thank you

Everything is always literally better working when "shifting" to AMSOIL I am slowly converting every engine in my "fleet" to AMSOIL, and every time i change it makes a difference. Sleds, boat, quad, saws, mill, mowers, car, trucks, winch.......EVERYTHING!!!

Did as advertised and removed the shutters from my transmission.

Hello, this is by far the best gun protectant period, proof, I have several pairs of snake boots that I wear, they make a nice pocket on the side of my calf muscle, so I drop in a pistol w/o a holster, in the past Lucas blue oil I would still have to wipe a gun down every night from where it touches my skin or sock if it stays up, or risk rust on blued pieces, with this spray I've tested months with no issues, so I've brought it down to every month once a month wiping it down no issues what so ever, also great lubricant also, so much so I've started using it in place of all the other sprays, wd40 ect..., definitely one of tbe best I have ever used so I ordered multiple cans and spray everything with it now, tow balls, pad locks, hinges knives , anything that slides or is in the weather ect... and I havnt found anything it doesn't work on an no messes like Lucas and other oils, try it you'll see! Thanks!

I bought this based on Amsoil's recommendation for a transmission rebuild but it meets Honda Z1 standard, not Honda DW-1. The Fuel Effecient ATF with blue cap is what you want if you have an older Honda.

Changed trans fluid in my 16 2.8 Duramax and have decided to use it in my Allison as well.

So far so good. I forgot to order 2 more quarts.

Changed my tranny oil, and before I did, never notice any problem, after changing it with AMSOIL, made a big difference in shifting.
