The Best motor oil I have used. I recently began using this brand and 5W-30 instead of 0W-20 in my Chevy Silverado; noted smoother operation and no lifter ticking sounds. There feels like there is better engine protection which should add to long-term durability. This is compatible with trucks as well as cars. Probably adds a few better numbers on gas mileage too.
