[This review was collected as part of a promotion.] I change my oil every 3 months (approx. 3000 miles) and use penzoil. My truck has over 260,000 miles and is still running strong.

I put high mileage in my car for many years and never had a problem with my engine. Only problem I had was getting rid of my perfectly good well loved car that still had lots of life left in it thanks to this oil!

[This review was collected as part of a promotion.] My truck runs smoother since using this oil. Only 72k miles on engine but quieter running than conventional oil.

I live for penzoil high mileage 10W30 as I have a 1992 Dodge Dakota that still runs like a champ has over 200,000 miles on it thank you Penzoil and I can always use a new tool box Merry Christmas and Happy New Year

I have always used Pennzoil High Mileage in my last vehicle which had just shy of 300,000 miles on it. It still ran good as new when I got rid of it. My current vehicle has over 150,000 and you bet I still use Pennzoil High Mileage!
