Customer Ratings & Reviews

I have been using this xmsn fluid in my truck for the last 15 years. When I change fluid it still always looks new, truck still shifts like new. Good stuff.

I flushed the ATF on a friend's car using the Multi-Vehicle Signature Series AFT, and he experienced a solid 9%+ increase in gas mileage. The wear characteristics of the signature series products are unquestionably superior to anything else on the market. I drained the old fluid, and used Valvoline Synthetic ATF as an intermediary flushing agent to ensure maximum dilution of old ATF, then re-flushed using Amsoil Signature Series ATF. Also changed the filter using Wix brand transmission filter. (Fyi, I'm an experimental physicist, and have been using Amsoil products for over 40 years.)

Convenient packaging. Good seal under cap. Easy to use.

My 2020 Ford F450 with 41,000 miles had a recall performed on the new 10 speed transmission. They have had early failures of the needle bearings in the number 1 planetary. I changed to Amsoil ATF within the first month of taking delivery, actually changed all the components to Amsoil. The mechanic doing the recall allowed me to inspect the planetary and filter for signs of an early failure. There was no early signs of the needle bearings failure and no contamination in the filter or the pan. I had them refill the transmission with Amsoil ATF. I’m not an amateur on transmission repairs, I’ve spent much of my career rebuilding Cat engines and power shift transmissions.

I changed all of the power train components in my new 2020 F450 within the first month after taking delivery. It was almost hard to believe how much the power train noice was lowered after changing all of the components. This is the oil that I use in the transfer case.

This is the best product I have used in my 38 years of servicing my vehicles. The shifting in my 2012 Tundra is much smoother now. I’m impressed with this product and the company. They ship fast!

I’ve used amsoil signature in my track s2000 and it’s stood the test of time decided to go amsoil for every vehicle and just added the qx80 to the mix so far so good!

I use Amsoil products and all my cars and toys

Been using Amsoil for over 30 years.

Bit the bullet and drained/refilled my Rav. Got her with 126k, read all the forums and decided I don’t believe in lifetime transmission fluid either. On my second drain and fill now planning on 4x total. She shifts stronger and smoother @ 134k . I like knowing that the fluid is quality, synthetic and new I’m an Amsoil believer.

Made my vehicles shift smoother

immediate improvements on ease of shifting and towing, less friction

Amsoil has always had a quality product in which you can see the wear that's not present

I have used Amsoil in all my vehicles for over 22 years. All three vehicles run cooler and smoother because of these products. 1 of my cars had 280,000 miles before I sold it and it still ran like new. and I attribute it all to AMSOIL.

This was my first time using an Amsoil product and it preforms well. I like that it covers so many requirements.

Awesome stuff, I’m glad I switched over to amsoil I replaced all my fluids in my 2019 f-150 I would highly recommend

I don't have any complaints. I would use only synthetic ATF fluid and thought I would give Amsoil a try. I like their customer service and fast shipping.

Immediate improvement in my Titan XD and lasting protection.

After 10K miles in Ram 3500 , I am very pleased to say the Aisin transmission performs better than it ever had. While it worked fine before changing trans oil and filter I have to say the Amsoil trans oil has made shifts more consistent and smoother. I noticed in about 500 miles, but waited to 10 k to see if it was consistent, it was, I would certainly recommend this high grade trans oil. Thanks for making a Great product!

Nothing but the best
