Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by highly recommend Royal Purple I have been using royal purple since my first oil change. My maintenance interval is 7500 miles. Since my warranty is now expired I will Change oil at 12000 miles since that is where royal purple says to change it. I hope royal purple comes out with a high millage version of this oil. I am also using the royal purple filter for my kia. Ordering on line usually gives an additional discount. The order is waiting at your local store. September 26, 2015
