I would recommend this oil to .y friends..

Amazing product, 10/10 recommend!

its a great synthetic oil save me about $200 a year vs monthly oil changes

My wife’s 2017 Camry went from 20.5 MPG to 23.5 right after I started using the Signature series, the oil pays for itself just if fuel costs, I recommend it to everyone!!!

Very good quality of oil and outstanding life of oil. I have been very pleased with the performance plus the home delivery is awesome. Highly recommend

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)!

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.
