[This review was collected as part of a promotion.] I have a 1996 Saturn with oil consumption issues and I always put Pennzoil HM in my engine. Keeps it running like new every day.

[This review was collected as part of a promotion.] High mileage oil is just an awesome product for my car, I get better gas mileage and keep my engine just a purring. I can keep on traveling as long as keep using Pennzoil

[This review was collected as part of a promotion.] BEST. OIL. EVER for my car with 155K miles and counting. This is the REASON it still purrs like a kitten.

I used to work in a car care center and the only oil that came in a constant color and viscosity was pennzoil. I have used this product in my cars for several years and wouldn't use anything else.

[This review was collected as part of a promotion.] Tried this oil in our daily driver after using Castrol forever and was not disappointed. We have a new oil for the Gilmobile!

Just recently switch to the pennzoil high mileage oil and my truck is running like a champ. I change my oil frequently because I drive so much and this oil helps maintain good performance and gas mileage.

We been buying Pennzoil for our high mileage vehicle for a few years now. We have almost 300000 miles in it and I know it's because of the oil we use.

The Pennzoil "High Mileage" 10w30 has been running in my 1995 Toyota 4runner since I can remember.At over 200k miles this V6 is still running strong. Cannot convey in words my appreciation for this great product beyond Thank You.

[This review was collected as part of a promotion.] I started using in my rough running 1976 c10 and after about a week i noticed a vast improvement in performance.
