[This review was collected as part of a promotion.] I work for a drilling and irrigation company and we us penzoil on every one of our gas powered vehicles and equipment. two trucks we have our from the 90s and still run great thanks to penzoil!

I drove a 1998 Ford Expedition until I sold it in 2015. Always used pennzoil and never had any major engine issues. Sold it with 150000 miles and it still ran great.

I've been using this product for a while now and I've had absolutely no troubles. Since I have made the switch to using this Pennzoil motor oil, my family's car has been running flawlessly.
