With the price of vehicles today, I like to do all I can to protect my investment, so I try to use the best products IMO to maintain them in good working order. For me Amsoil is the way to go to accomplish this goal. Love the flex bags that make this job a breeze to do, especially in these hard to reach areas with minimal clearance.

Just change my fluid on my 2002 cavalier with this and very impress with the performance. My transmission usually has a whining noise when i accelerate at slow speed. Since the change it disappear. Thought this fluid helps that.

I was really happy with how fast amsoil shipping was. We all know they make good synthetic lubricants.. Only time will tell as to how good. But I'm happy with their products and shipping.

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.

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

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
