Customer Ratings & Reviews

I've used Amsoil over the last 30 plus years and never had a problem with any of the product. I use it in offroad vehicles, 4x4 Jeeps, turbo charged engines, NA engines and anything else that benefits from a high quality synthetic lubricant.

I have used Amsoil signature oil for over a 100,000 miles in my vehicle. I tried other oils but they did not last or perform up to my standards.

I can go a long time between oil changes with the signature series 5W 20 oil, it is amazing how much better my truck has been running since I have been using it. I haven't found a con with it yet, just all pros!

I have used Amsoil for many years, I use it in all my vehicles everything from my daily driver to my classic and antique cars, I even order it for my friends and family who all love how it works and the convenience of use ie. Once a year oil change.

I started using AMS Oil over 30 years ago, and left it for awhile. I tried Mobile 1 but did not like how it performed in my vehicles, I bought a new F-150 with eco-boost which I read runs higher in temperature, so came back to AMS Oil because it always held up better under extreme conditions. I have had the truck for over 2 years now and it knows nothing but AMSOil. I really feel I will get the performance and years I want out of my truck with the help from AMSOil.

AMSOIL Signature Series 5W-30 Motor Oil keeps my car running smoothly.

I use Amsoil for the peace of mind it gives me in my cars, trucks, motorcycles, generators, and lawn equipment. I have a 1985 Craftsman lawn mower that has never had anything but Amsoil in it and the motor is still going strong! That's proof enough for me.

I use the product in my 2013 Dodge Ram 5.7L. I believe I have increased fuel mileage and the truck runs great!

I have used Amsoil products since 2003. Never a problem. I have recommended it to friends without any qualms.

Ever since discovering this oil in 2005 I've never used anything else, and it's never let me down. 15k miles between oil changes and it's still gold in color not black like others.

I have been using Amsoil for years. Commutes for me is 40 to 50 kms oneway and I can run Amsoil and never have to add oil. Had an old car overheat in Calgary one summer due to traffic on the deerfoot trail and there was no problem afterwards with the car or the oil.

Amsoil is de bessss!

The Oil performance is good and produce annual saving near to $90.00 per car.

Love the oil never had issues power foam is the best out there if ya know how to use it correctly.. very happy with the results and products..

Great product, love the extended drain capability.

Smilinjack has been using AMSOIL 1030,1040 2Cycle oil, Power Foam, oil and air filters and Performance Improver continually since 1979. Once we tried it, have never ever needed or used anything else. Automotive use, lawnmower, lawn tractor, boat motors and my portable generator all perform well with AmsOil in the crankcase. Excellent products. Knew a good thing when we first found it and will never go to anything else. EOM

I have been using Amsoil in every vehicle I have owned for the past 15 years. I like the extra protection and only changing oil once a year.

your car runs great
