[This review was collected as part of a promotion.] Keeps my jeep running well..Very good product..hardly need to change the oil.

My truck leaks less with Pennzoil High Mileage! My truck has 295,000 miles and is only getting started!

It makes my vehicles with high miles feel like they are much lower! Have never had a problem with this product it has always been A+

My cousin uses it in his Fed Ex truck that he puts high miles on every month and hasn't had any motor probles. It works.
