[This review was collected as part of a promotion.] I changed the oil in my personal car to Pennzoil High Mileage and the lifter noise went away shortly afterwards. Nice for 176,000 miles! :)

I run the High Mileage Pennzoil and have always been pleased with there products. This oil kept all the internals of my engine looking brand new, I always recommend Pennzoil.

I recently went to this from conventional oil and am pleased at how well it works in high mileage vehicles. I can buy it at work with a filter cheaper than I'd pay at an oil change place to do the oil change.

[This review was collected as part of a promotion.] I have been using Penzoil for over twenty five years..still use it in my 81 Blazer to my new Ford F150

I use this product in my 91 safari van as it has over 150 thousand miles and we drive a lot so I try to protect the engine as much as I can! Thank You Pennzoil!

My husband and I have tried every oil out there. Pennzoil High Mileage out performs all other brands...hands down. We have been using Pennzoil High Mileage for the past 5 years and will never use an other brand.

I've had a minor valve gasket leak for a few years and this high mileage oil has kept the leaking to a minimum while keeping the engine running as normal as could be expected.

[This review was collected as part of a promotion.] I use Pennzoil High Mileage oil in my wife's F150 with 160,000 miles and my Explorer with 125,000 miles...never an issue and a really great price!
