[This review was collected as part of a promotion.] Been using Pennsville for 25 years on numerous vehicles and have never encountered any engine wear problems. EVER.

I only used Pennzoil conventional in my Rx-8 - the mechanics that worked on it always commented how clean the components were. It's the only oil I know I can trust!
