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!

I am using this in a higher mileage Honda. 6 cylinder. My oil consumption has went down significantly between changes.

This oil is of course is the best. Been using it for years, no problems. I do beleive you gain horsepower by using this !! Great oil !!

All of your oils are excellent, but these are superior!

I've used Amsoil products for decades with complete confidence and great results. My current vehicles have 206,000 miles, 166,000 miles and 101,000 miles. Never any internal engine problems. All running great. I also use Amsoil (Z-Rod) in my fourth vehicle, a '47 Hudson and all my boats and mowers.

I have used Amsoil on all my cars for the past 40 years. I am currently using the 5W -30 100% Synthetic for the smaller engine on this small SUV for better lubrication. Recently took a 5,000 mile trip and the car did exceptionally well. Fun to drive.
