[This review was collected as part of a promotion.] I have 2 cars and 1 truck all over 100.000 miles. It has improved oil pressure.

Use this in my 89 Ford Crown Victoria LTD with 175,000 miles. Still good oil pressure less than pint low at 5,000 miles.

[This review was collected as part of a promotion.] Purchased this for my older truck. Works great and keeps the engine clean inside.

I have been using Pennzoil's high mileage for many years! Never has failed me and makes my engine purr!

My local oil change place suggested making the switch as the ole' gal hit 150k+. Continues to run great and no leaks anywhere.

My truck leaks less with Pennzoil High Mileage! My truck has 295,000 miles and is only getting started!
