We switched to the high mileage and now the car runs better.

I bought my car 2 tears ago used and have used only this for my oil changes. My car runs amazing!

Always put this in all my high mileage cars and still going strong!

I use the high mileage blend to keep my 14 year old Subaru running clean and dependably.

Penzoil hi mileage is great stuff would definitely recommend.

THIS OIL (PENNZOIL HIGH MILEAGE) WORKED GREAT IN MY 1988 GMC PICKUP - IT DIDN'T BREAK DOWN....

Works well for cars with 150,000+ miles. Use it for every oil change

Been using it for years.....my trucks engine goes forever

After 3000 miles oil still looked new and keeps its viscosity level

I have been using it in both my high miles cars it'd great
