Customer Ratings & Reviews

I watched a review series on sensor-u-tube (project farm) about synthetic oil brands. He tested the top 10 (I think) and Amsoil won hands down in every catagory!

Used in 3 of my vehicles excellent results

I have used Amsoil products for years with great success, putting hundreds of thousands of Km of trouble-free driving with no oil consumption or any evidence of wear

Outstanding

I put it in a '06 f150 5.4 3v and it definitely has less valve train noise and the engine gets quiet as soon as it idles down.

Ordering, shipping and delivery were perfect. Finally had time to get it serviced. Now we just need to get some miles on it.

Fantastic motor oil. Highly recommend.

Switched from RP to Amsoil. Great product. Happy with the prices and convenience as a preferred customer.

I use this oil for years and my car has over 190K on it and running great. Wont change it for anything.

As always excellent oil. After just 1500 since oil change I have gain .4 miles per gallon on my 2020 GMC Sierra with 6.2 liter engine. Smoother idle quieter engine. Very please.

I run this in my 2001 mustang GT Bullitt with a procharger supercharger never had any oil related problems whatsoever and when I pulled the valve covers off to do a gasket change everything looked brand new none of that gold discoloration you usually see in the valve train and the car has 52,000 miles and makes 450 rwhp so I’ve put it to the torture test so to speak thank you for providing me with the ultimate protection to stand up to the abuse I dish out to my rides. If you actually care and work on your own cars so worth the extra couple dollars a quart over conventional brands available or even high performance products do your research and you will not be surprised why Amsoil is #1 only thing close is pennzoil ultra platinum but it’s burn off rate is not even close and the only place you can get it is offline or a dodge dealership because it’s what they run in the hellcats and other srt vehicles, ps. I did not and will not run it in the mustang never have never will but I did run it in my wife’s 07 Honda accord before I had a membership with Amsoil but I will be a devoted customer to Amsoil from here on out it was just a affordable option at the time.

Worth the price for the mpg gains

Great product worth the increase in gas mileage, and smother cold starts

I use this oil because I have a 1.5 liter with a supercharger. It helps keep the cars oil clean and cool at high revs. Also it lasts a good long time. I only change my oil once a year cuz I only drive about 5K a year. But I am assured that this oil will not break down in time like conventional oil. I have been more than satisfied with it and use it in all three of my vehicles.
