Customer Ratings & Reviews

Once a year oil change and I'm sold. I tow a 7X16 cargo trailer 50% of the miles I put on. I put the proven best oil in and only crawl under the truck annually now. No oil loss with 160K on the truck.

I have always used synthetic oil in my vehicles and used Amsoil in the past. When I found I could be a preferred customer I was very pleased to begin using it again.

Best oil iv ran so far the car continues to run super smooth even with a couple days at the strip

This oil is just the best of the best. Proven quality on any test out there, this oil will help your vehicle engine perform to its potential. A plus!!

I use this in a supercharged hi performance vehicle. It gets worked hard. When I change the oil you'd never know.

Another great product love amsoil

Personal use on 2012 WRX, with 90k miles.

I have used this oil for 203,000 miles since my FJ Cruiser was new. It is the best!

I replaced the enfine and granny in my car over a year ago. The oil and tranny fluid have done fine since. I'm pleased with this product.

Excellent oil. I have used it for years without an issue.

For my new car, It is running much smoother receiving more MPGs than OEM oils and/or even the best over the counter motor oils. Thanks!

What can I say? I bought it for a friend with a hi performance engine. I've used Amsoil engine oils for over 35 years. Always had great longevity and reliability every time.

Use in all my late model cars

Have used this product in my wife's Subaru Crosstrek since new in 2014. It has worked flawlessly ever since. I wouldn't use anything but Amsoil in my wife's car as she has to travel through desolate territory just to get to and from work. I absolutely need it to be there for her. It does the job great.

Great oil unbelieveable mileage no problems whatsoever

I am using this oil lately and I am very satisfied with it. Usually I change it every year but I didn't exceed 9500 miles. Engine is running smooth and quiet. Thanks.

Good product

I use Amsoil in my 4 vehicles and ZTR mower. It's the best.

Amsoil is the only oil that has consistently been able to withstand the unbelievable abuse I put my engine through.

my Subaru forester says thank you and purring along for nine years could not be a happier person.
