I get better mileage using this product

I've been a very happy AMSOIL customer for twenty-five years now. I trust everything that they offer. I can't recall ever trying an AMSOIL product, whatever it be, that wasn't better than what I had been using. Prior to finding AMSOIL I'd lost an engine using Mobil One. About a year later I bought a brand-new car so I ordered data sheets to study several brands of synthetic oils and I found AMSOIL to be the best. Over the years, I’ve come to believe that everything AMSOIL offers is the very best in the world. What many people may find an alarming thing for me to say is that AMSOIL products cost less in the long run. Their oils and fluids last and last. I change motor oil once a year and that works out to be much less money than using cheap low-quality oils and changing it every three thousand miles. Any oil requiring a change as soon as three thousand miles can't be any good for my car, so that would be wasted money from the onset. I own four cars and a heavy-duty truck and I love each of them so I want only the very best products going into them. I have no intention to ever try any other brands because I wouldn’t want to give up the peace of mind that AMSOIL brings to me.

I have used Amsoil products exclusively in everything I own since I was old enough to drive. I have had multiple dirt bikes, ATVs, and UTVs through the years. I also have owned several pickup trucks (gas and diesel) because I haul commercially for a living. Thus, my equipment gets used very hard. I have never had a single issue in ANY of my equipment due to poor oils or lubricants!! That should tell you something if you are considering buying Amsoil products, just do it as you will be glad you did!! Amsoil doesn’t cut corners. They do it right and make superior products!!

Can't get any better. This fluid will protect and possibly help restore your transmission. The cost is worth the extra protection.

I just flushed out my 2019 Kia Stinger and put in the Signature Series fluid. The first thing I noticed was the temperature drop in just daily driving. This twin turbo puts quite a strain on this AWD and I'm already seeing temps average 20 deg lower. Next is how much smoother if shifts, better than when I picked it up brand new off the lot!

I use AMSOIL in ALL my machines! Recently changed my transmission and transfer case fluids on my 2016 Chevrolet 3500HD Suburban to AMSOIL ATF. The "Easy-Pack" almost made the job enjoyable!

I have used this transmission fluid for my 2003 Jeep Liberty with the 3.7 and the 42RLE transmission and it has not thrown any fits or overheated since installing this fluid. I have taken my Jeep to the dunes once and done a ton of highway and city driving with this installed and it seems to be just fine. Also did the transfer case and it hasn't had any problems either.

Made my transmission feel like new.

Stickers please.

I had to call three times to get my order. I love the product but the customer service sucks. They lost my order twice. But the transmission oil is great my truck runs and shifts a lot smoother.

I love this for my 4R100

Found this Awesome ATF thanks to “don smith” on YouTube , I replaced the oem conventional garbage on my 2017 Camry and the shifts feel smooth like butter

The pouch is a lot easy to handle. The fluid made a huge change on shifting. A lot smother and still with power. Highly recommended.

My 2003 Subaru outback 2.5 L automatic transmission decided to start giving me fits when I was driving to California here recently. After two hours of driving on freeway speeds my front wheels started to jerk right and left on the highway it was pretty chilling. To make a long story short got to a service provider in the codes read that needed a new transmission. With a little over 300,000 miles on the transmission there probably right but I did not want to spend two grand grand for only a used transmission. So I had a service lube station drain 4.2 Quartz then refill with Amaoil ATF and change the external filter. It seems to have minimized it greatly and I will be doing it again every 10,000 miles.

This is great transmission oil. We changed out the oil in my brothers 2012 ford f350 and the hard shifts went away!

It speaks for its self. This stuff is good.

I can go longer drain intervals using this product. Better protection too!

This is the first trams oil change in my 2017 GMC. It is used mostly for trailering. The trans shifts great and the temp is well within limits.

Flushed out the original fluid at 50K with Amsoil, shift quality is greatly improved. Car is tracked once a month and fluid is holding up well, had it tested by third party at 5000 miles and results were excellent!!!!

the best automatic transmission fluid out there. took care of my judder in my 2015 8 speed vette!
