[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.

This is the only brand of oil I trust for my vehicles!! Being a teacher, I would give Pennzoil an A+

[This review was collected as part of a promotion.] I run many miles and this oil seems to last longer and better than anything else I've tried.

I've always bought Pennzoil products - they are a tested brand and great company that puts out great products!

I buy this each oil change its all i use. I get the high mileage cause we love to travel. I wouldnt run any other oil. Team penske all the way!!
