My car is a 2008 Chevy Impala LS with over 170,000 miles. This product amazes me. I get better gas mileage and it feels and runs better Now that I use this.

i have been using penzoil since i could open a hood.i use it in all my trucks,like my father did .it extends the life of my 36 year old ford motor ,i never have a concern about it not starting thanks to penzoil

Great product that truly performs well in our old vehicles that are over 20 years old. Wouldn't buy any other brand and am thankful for the quality products such as Pennzoil High Mileage Vehicle.

I have used Penzoil oil in my 93 chevy s10 since it was new now has over 200000 miles still runs great and uses no oil between changes. This tells me to never use any other brand of oil in my vehicles or even my lawn tractor!

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!
