[This review was collected as part of a promotion.] I have run Pennzoil in my Fusion from day one 140,000 and still going strong

We used this on my daughter's first car. It was worth every penny & made a difference on how the car ran.

I bought this because I own a 1996 that has high mileage that belonged to my father & he always used Penzoil so its a family trusted tradition
