If you have done any research y’all know that this is the best product on the market, bar none. I have been using this product for nearly 30 years. No issues ever. It use to be expensive, not any more. It should be more expensive this is best lubricant period.
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!
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.
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 .
Bottom Line
Yes, I would recommend this to a friend.

Bought the wifes 13 Pilot with 15x,xxx Miles. Since I first Changed oil I have been using Amsoil. We are now over 210,000 With no issues.
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!
