Customer Ratings & Reviews

I been using it for about three years. I absolutely approve 💯 %

I have been using AMSOIL products in all of my vehicles, including motorcycles, for well over 20 years. I won't use anything else. AMSOIL makes great products, and I recommend them every chance I get.

I been used amsoil for the longest because of their quality. 1A

GREAT PRODUCT, MAKES MY CAR QUITE.

I have been using this for approximately 12 years. Great oil that provides easy starting in cold weather.

Got this product for my wife's 2017 Jeep wrangler Willys edition. Will only run amsoil products in this new to us jeep.

Really good oil at a great price.

Love amsoil products. Actually bought this product for a friend of mine for his Chevy pickup because he heard me talking about how good amsoil products are.

Only oil would use.Excellent results over past 20 years.No other oil in my vehicles.

I like the oil. I always try to get the filter to go with it. I don’t extend my change intervals. I have noticed that the filter is heavy. I guess it is catching something. My truck runs good. I am a little afraid to cut the filter to see what’s inside. Could this be the oil sludge? I like the gloves that came with the oil. The cardboard funnel. I have yet to find a use for it. I have a skid plate and tried to use it to direct the oil away from the inside of the skid plate, but it was too small. Overall good oil. It would be nice if it was not so expensive.

Best oil on the market! Wont use anything else

Amsoil Signature Series 0W-16 installed in my 2024 Kia Niro hybrid for its first oil change (1,900 miles). With the on / off operation of the gas engine, I wanted the best oil for it. Also like the low pour point for cold winter starting. I like the great additive package too. I have been using Amsoil since 1998 with great results and no issues.

I run this in all our vehicles including my daughters. The girls typically travel less than 20,000 miles per year so I change their oil once per year. In my turbo charged vehicles, I change at less than 10,000 miles. I typically see a 10% fuel consumption savings which, I feel, is a testament to the reduced friction.

Great product for my Camaro 1LE. Oil of choice for my LT1 engine, better than Mobil1

Buddy of mine owns a Ford F150 had to replace the engine so he wanted to give Amsoil a try after I had given him my thoughts on how good Amsoil is. The new engine is still in the "breaking in stage" update will come later.

If I could not get this oil, I would be forced to use Mobile One.

U.S.A. made, 100% synthetic not blended, increase fuel mileage, heat displacement, leaving film so you don't have to worry about cold start with no friction, I would recommend this product for every type of motor. They manufactured for everything and every brand.

Been using mobile one for many years with no problems. Known about AMSOIL my whole life and was always wanting to go to AMSOIL. The membership and free and fast shipping made it an easy decision All of my personal vehicles are going to AMSOIL now. Wished I went this route sooner. Best quality oil on the market. Great company. Highly recommend AMSOIL.

Since 3 years now i used signature series oil in my truck.

Well pleased with the product. The testing and results seem to prove that protection for the long term is guaranteed. The Q & A regarding the oils are quite informative and have caused me to rethink many of the (incorrect) assumptions I have made over the years. Currently, I'm driving a Durango SRT and am well pleased with the smoothness and performance of the hemi since changing to the Signature series oil recommended. It's always good to research potential issues with an engine/power train and see how a specific action will help to mitigate a given problem. In the case of the Dodge hemi, premature cam and lifter wear seems to be an issue with engines left to idle for extended periods and/or run for extended oil change intervals. The Amsoil Signature series oil is well suited to mitigate the problem. Time will tell, but currently 70,000+ miles have not changed the 'as new' performance or noise levels in a great engine.
