“I put Royal Purple in my F-150 truck last weekend …and made the trek to Vegas. Usually, I get 330-340 miles per tank (25 Gallon). This trip (equipped with Royal Purple) I managed to get 390 miles to a tank. Thinking that I could have been mistaken on the mileage, I tested it again on my next tank (which had far less highway driving).

Thus far, I’m at 340 miles and I have a little less than a quarter of a tank left! Needless to say, I’m more than impressed. …Please pass on my congratulations to the rest of the Royal Purple team for such an outstanding product!”

“I am a service advisor for a well-known national service shop …Since I switched to your products, I can honestly say it’s the best full synthetic oil on the market today. …I have customers call me back and ask if we did anything other than an oil change because of how smooth their vehicles were running after switching to your oil.

Thank you for making such a great product. You’ve gained a lifetime customer.”

—Drew van de Putte, service advisor
