I Have been using this product for about three months now on my vehicle. I think it has made a big difference in the way my truck runs and performs!

[This review was collected as part of a promotion.] Best oil on the market with good protection additives

[This review was collected as part of a promotion.] I bought it for my Ford and I drive a lot to and from work it is an amazing product

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

I love this stuff. I have a Ford ranger with 350xxx miles. No rebuild on the motor. Keeps is running strong. Thanks Pennzoil

I have been using this product since it first came out and all of my high mileage vehicles have not had any major internal engine problems!

[This review was collected as part of a promotion.] Used it in last car and vehicle was still going strong after 215 thousand miles!!

[This review was collected as part of a promotion.] have 245,000 miles on truck,all of them with Pennzoil H.M.. 60 lbs of oil pressure!!

It lasts longer and keeps my engine running smoothly. I won't get an oil change if they don't have Pennzoil High Mileage.

[This review was collected as part of a promotion.] I use this in my Chevrolet Suburban with 178,000 miles. It stopped my oil consumption problems.
