Customer Ratings & Reviews

Changed the differentials and transfer case. Noticeable improvement in quickness and less noise. In addition, "felt" like it was a smoother transfer. Anecdotal at best for the moment. We'll see at the next interval what condition the oil is in. Due to that inspection, I don't think asking for an evaluation before a service interval is quite fair or accurate. That being stated, I am confident it will perform well.

Great product. Easy install. And the fact that it is superior gives me comfort and satisfaction. Switching everything over to Amsoil products

For a maintenance nut like me it was only a low stock at the dealer and no aftermarket replacement that lead me to Amsoil. I had no expectations of the miracle in the bottle. Full lockup sooner, lower operating temperatures, smoother and more zippy performance from a Diesel Mercedes Benz!. Yes its true. If anyone's looking for a substitute to the blue gold that they sell at the dealers to do your Transmission service... Try this Red miracle in a bottle. Cost less, works better, easy to get, easy to use and man the difference is like night and day. Grateful Amsoil, I'm sold. Paul- in Calgary 2012 MB W166 Blutec.

Great tranny fluid. I did a lot of research and this is the best. I commute 400 miles a week for work. I noticed I am getting a couple of miles per gallon more and the shifting is a little smoother. I notice it more on downshifts. I have been using Amsoil for many years and firmly believe it is the best. I have been an aircraft mechanic for over 30 years and take all the claims made by companies, with a grain of salt, but another mechanic turned me on to Amsoil and probably will never switch to anything else. Just my two cents.

Great product, highly recommend!

I’ve been using AMSOIL products for years, never disappointed.

I started using Amsoil transmission fluid about three years ago when my car had 86,000 miles. Right now my 2015 Chevy Trax has just crossed 171,000 miles and I flush the fluid at every 45,000 miles as recommended by GM.

I purchased a used 2009 Honda Pilot a few months ago and wasn't long I not only inherited the prior owners problem, but a Honda problem. Long story short, I decided to replace the existing ATF in the vehicle to the best fluid I knew of to help resolve some of the problems. I was a little disappointed my mechanic was only able to replace half the required amount of Amsoil ATF. The fresh fluid hasn't been in there very long but as near as I can tell so far the Amsoil has made a bit of difference as far as eliminating the transmission fluttering I was experiencing. I selected the Signature Series as my plans were to tow my Aluminum boat for fishing as well as other stuff, but sadly haven't been able to so far. My plans are to drain and add more of the new ATF in around 6000 miles to insure the majority of fluid in there is the Amsoil. I have only rated it at 3 temporarily until the majority of the fluid has been swapped to the Amsoil Signature Series. We'll see what happens, no complaints with the product so far.

Looks GOOD,SMELLS GOOD,IS GOOD, 👍

I purchased a 2002 Ford Ranger with 14,000 miles on the odometer. I decided to service all of the fluids as preventative maintenance. I am exceedingly happy with my 5 quart purchase. Sincerely Robert

the best synthetic tranny fluid ever made!

The 6L80e transmission requires Dexron Vi, this Transmission fluid recommended for use where dexron Vi is required. I do a drain and fill every 30K (6 quarts) the transmission shift smooth with this fluid and transmission shifts great in the colder weather.

Since I changed my tranny fluid in my Ford 10 speed it shits way better

Great product. I use every 60k on my vehicles, no complaints.

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!
