Customer Ratings & Reviews

Works great in my high mileage cars. Great product

Best oil product ever made. Provides better protection compared to the competition now days. Doesn’t even come close to it. I would highly recommend people to use this or the signature series. That’s if you do your own oil changes. Not many shops will let you bring in your own oil.

I bought this oil for my daughter's car. It's perfect for her application as she mostly drives on the highway to her job. It fits within her mileage driven per year. Performs great!

I’ve never been gentle on my vehicles. I expect the best out of them, and to keep them running on top shape, I keep them on a steady schedule of premium fluids, and AMSOIL keeps the internals safe from my spirited thrashings. You guys keep sending the oil, I’ll keep sending it to the limiter, thanks AMSOIL!

Nothing but quality.

I use Amsoil in all my vehicles. Motors, transmission, and axles. Thier products work great every time.

Love ams oil I use it in my jeeps my duramax and my daily driver

2007 GMC Envoy 5.3 liter. 168000 miles. Removed engine for broken valve spring. Upon tear down the engine looked amazing. No varnish, home scratches visible on cylinders. Replaced timing chain and did a AFM Delete. Now have 186000 miles with 0 oil issues.

Use this on my personal vehicle all the time. Works great, however I change it every 3-4000 miles

Awesome product would change for anything

I have a 2004 chevy silverado 4.3 V 6 with 145,000 miles on it and it runs like a clock . Doesn't burn oil , my tail pipe inside is a light tan . If it burned oil it would be black and sooty . Thanks Amsoil for a great product .

Confident in performance and protecting engine

This was my first time using your oil. I couldn't believe that this oil quieted the engine in my new truck as much as it did. This is the only oil I will be using from now on. Thanks!
