This is the oil my Dad used in everything he owned. Including our Ford farm tractor. I grew up with it. My Mustang gets it too!

[This review was collected as part of a promotion.] Classic product that never fails. No need to look elsewhere

Only product I have ever used on all my vehicles since I've been driving. I have never tried another product and never will.

I always use this in my car. I don't do it myself, but I make sure where I go only uses Pennzoil so I know that's what is in my car!
