Customer Ratings & Reviews

I just love the longevity of this product

Noticed an immediate difference in engine noise. I will not use any other oil than Amsoil in my vehicles

Great product line for all your engine needs.

been using AMS oil it for years hasn't disappointed me yet and cuts down on oil changes

I have driven hundreds of thousands of mile using Amsoil products and never had a lubrication issue. Great staff and service as well. Thanks Amsoil team!

been using AMS oil it for years . hasn't disappointed me yet

Use amsoil in all of my vehicles from my high performance 4 cylinders to my EcoBoost to my generator and my kids 50cc motorcycle.

Ever since I bought my 2019 Sierra Denali 6.2 I’ve been using Amsoil in it. I get about 7500 miles between oil changes and I’m really happy with the way the motor runs.

Top product recommend to anyone.

Best oil money can buy

Use this in two gas cars not familiar with high mileage but more stop & go driving. Considering the NY temperature variations, this oil is almost as clean when being changed after 25,000 miles, as when first put in!

Great oil from a great company. Using this oil after switching from a competitor. It is a better oil. Highly recommended to my family and friends.

Signature Series is the number one oil, proved through testing and comparison, Amsoil is the best protection for your engine.

Can't get better than Signature Series. Definitely worth the small amount of extra expense for the extra protection.

First time trying amsoil in my truck. Made the switch from Rotella T6 to Amsoil so far I’m real happy with it definitely is quiet the engine down!

I would recommend Amsoil product to all my friends and relatives. Can never go wrong at all. Huge difference I have noticed since I started using amsoil

Just rebuilt my first engine..broke her in with 10w30 dino...went 3k with mobile and figure why not? I just a little 1.8 celica gt engine at 183k and realized I just rebuilt an engine and after that I felt she deserved the best. I'm confident after I put in the whole jug that I could run it till the stated 15 to 25k but oem says 6k. I'm confident with amsoil that I'll break 300k no sweat.

The day I bought my 2005 F250 home I dumped the stock oil and refilled with Amsoil 0W20 and a EAO11 amsoil filter. That was 16 years ago and it still going strong. I would never use any thing else.

I have been using this since the day I bought my Ford Explorer and have never had a problem. Bought the truck home and dumped the stock oil and refilled with Amsoil 5W20 and a Amsoil AEO17 filter that was 3 years ago and will never use anything else.

Have used amsoil in all my vehicles for over 30 years , and have never had problems, if you are trying to decide if you should use amsoil its a no brainer , your car will thank you for years!!
