[This review was collected as part of a promotion.] Have used Pennziol most of my adult life.... a great product and a name you can trust...... and when I service my car it comes out almost as clean as when it was put into the engine.

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.

Pennzoil 5w30 was used for my first oil change in my new S-10 in 1991, and still is. It's also the only oil ever used in my 2005 Silverado. Everything I own gets Pennzoil!
