I have used pennzoil since my cR was new and as the mileage grew I switched to the high mileage

I use this on my daughters car which has many many miles. Love it.

I have used pennzoil in all my cars , I would tell anyone this oil is the best.

I have been using this product for a while. I really like the way it performs.

This is the only oil I trust to put in my 1978 Camaro! Great product and great price!

After using this for my car I can actually feel it run smoother and more reliable then before

Use the high milage in my truck and have never had an issue.

Used on a cars oil change awesome. Qauilty of life

It has been great to keep our 2001 Montana going still after 367,000 km.

This is all I use in my 2008, 150,000 mile Impala.
