helps keep your car running great, when you change your oil regularly

Been using pennsoil high mileage on grand Cherokee for years no problems

Helps protect and keep engines with high mileage running smooth and efficient in any condition.

Only oil I use for my 2007 Silverado 190,000 miles

I drive some good high mileage cars and this stuff is great! Love it!

been using this oil for years and have about 240,000 miles on my truck.

I run this in my suburban that has 280000 miles on the engine never had a problem with it thank you

Great product I use in all my vehicles!!!!! It never let's me down.

Use this in a 96 Buick. Keeps the engine running as smooth as possible for an older car.

It is the only one I use. Another great product bearing the Pennzoil name!
