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+

Tried for first time about a year ago... Liked it so much use it on my wife's car as well!! Cars are running great! Highly recommend!!

My truck has 176,000 miles and it runs great. I use Pennzoil high mileage every oil change and will continue to use it as long as I own it.

I have been using Pennzoil High Mileage for a while in both of my cars. I'm sure it's the reason my cars both still run like the day bought them new!

This oil comes out clean as the day it was put in, even if I stretch the milage past when it should have been changed.

I have had problems with most oil on the market but o have found pennzoil to work the best in my cars
