Customer Ratings & Reviews

I’ve been using AMSOIL since 1996. No complaints. One cat has 298,000+ miles and still going strong.

I had to replace a timing chain and camshaft actuator sprocket on my 2013 Accord, which required removing the front engine timing cover and valve cover. This engine had 75000 miles, with engine oil changed every 5000 miles. When I removed the valve cover I was shocked! There was no sludge or residue anywhere. It looked like a new engine. I use Amsoil 0W-20 Signature Series oil, and after seeing how clean this engine was, I would NEVER use any other oil. People that use Amsoil have always bragged about how good it was, and I just took it with a grain of salt until I started using it. Now I know. Can't recommend it highly enough. Expensive, but worth every penny. Get the Preferred Customer account because that will pay for itself.

My 1996 Chevy Impala, with 21,000 original miles only gets the best of everything. Amsoil Signature Series Synthetic motor oil ( remember, only the best of everything)!

El producto me llegó bien pero la página me dio 2 errores de compra en el cual me mandaban un email diciendo que la compra se había cancelado y aún con todos mis datos correctos, aún así el producto llegó aún diciéndome ustedes que el pedido se había cancelado, tienen muchos errores en su página para poder comprar online

This is the best motor oil in the world. I just put it in my new Atlas, and it runs even better and smoother now.. also mileage went up.

Great product & a history of proven performance

My late husband and I were farmers and only used Amsoil in our equipment. Now i use the same oil in my pickup as i want to have it for many years. I also use it in my motorcycles. Excellent product for the motors I care about.

The is by far and away the best motor oil on the market. I would not use anything else in my car. Excellent customer service!! You will not go wrong!

I’ve been using Amsoil for over 20 years in everything I own. I’ve never had any issues. It’s the best oil in the market.

I have used Amsoil exclusively in all my vehicles for close to 30 yrs., and I'm happy!

Over 20 years of using Amsoil products.., no issues with my cars engines thanks to Amsoil 👍

Been a preferred member for many years, but price on this keeps going up. Considering not using anymore. Ten bucks a quart was my max. Too bad I loved this company and products, just can’t do it anymore.

Looking forward to putting Amsoil Signature Series in my new pick up, lawnmower, pressure washer, and generator. Great oil and great customer service.

I have been using AMSOIL in all my vehicles and motorized equipment for years now and I can honestly say I have yet to experience any issues of wear, and know it has extended the life of all the motors.

Been using AMSOIL for 3 years now and I can honestly say it’s the best on the market my 3 vehicles run much quieter and smoother I highly recommend AMSOIL can’t go wrong with AMSOIL.

Was introduced to this product about 2yra ago. I had been using Mobile One which was good however, after using this product in my Lexus, I began using AMSOIL in my wife’s car. Both cars run smoother and along with Upper Cylinder & PI gas treatments, I’ll never go back to Mobile One. Great U.S.A. quality product!

Excellent

This is my first time using any Amsoil product, but I decided to use it for the used Camaro SS I just bought. I have no idea what oil was used before, but I wanted to change it to Amsoil based on a number of recommendations I saw for my particular car. I may end up using this stuff in my other cars as well.

The Signature series oil is definitely top shelf oil. I have been using it in my Focus since 150k miles. I am now at 461k miles on the car. This oil keeps it going. Less oil changes, since you can run more miles, is a time saver and money saver. I will not use any other kind of oil.

With other synthetic oil my oil pressure light would flicker on, I switched to Amsoil and have not had that issue again
