We switched to Pennzoil conventional 5W30 a few years ago and our vehicles run better than ever. We get great gas mileage and with promotions get Pennzoil for a good price. I will definitely recommend and continue using ANYTHING by Pennzoil!

Been using Pennzoil my whole life. I remember my Dad teaching me how to change oil when I was a young boy. Only oil he would use. I have used it in every vehicle I have owned since. Never left me down.

My father always had a case of this stuff on hand- it's the only oil he'd ever use. All of his vehicles, from 1970 Dodge Challengers to Ford Aerostars and everything in between, have ran smooth as butter.
