[This review was collected as part of a promotion.] I've used this years, on multiple high-mileage vehicles, and it works great!

It has kept my car running great for over 108,000 miles. I can't imagine using any other brand of oil, Pennzoil is the only name I trust.

I have a 2004 Toyota RAV4 . It has approx 165,000. Live this in my truck. Works very well in my engine ! Thanks Pennsol
