I thought motor oil was motor oil ’till I saw an auto show that talked about Royal Purple. I put it in my slightly modified 2002 Camaro and it made a very noticeable difference!! ...Your oil has smoothed it out COMPLETELY!!!! No more idling all over the place for the first 10 minutes. It’s smooth sailing from the get-go. Way to go guys!! - Scottie Krakow, Houston, TX
