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.

[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 is the oil I use in my 1989 Buick Century. This car has been the best car in terms of dependability and I fully believe that a huge part of this is the wonderful oil I have used in my regular oil changes!!!

Great product that truly performs well in our old vehicles that are over 20 years old. Wouldn't buy any other brand and am thankful for the quality products such as Pennzoil High Mileage Vehicle.

[This review was collected as part of a promotion.] My car needs conventional oil and Pennzoil is my best option. Ever since I changed over, my car hasn't had any oil issues and keeps my car running smooth.

[This review was collected as part of a promotion.] I've used this in my truck ever since my truck hit 200,000 miles and now it's over 255,000 and hasn't missed a beat.

[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.

[This review was collected as part of a promotion.] I buy this every time I change my oil in my trailblazer with 150,000 miles and it loves the oil. Used to used quaker but that gunked up. This Pennzoil doesn't burn at all in my car

[This review was collected as part of a promotion.] I use this on both of my cars and the outcome has been great! We live in cold country MN and it has worked wondrous for us.

I have been using Pennzoil High Mileage for my '97 Camry. She now have over 360,000 miles. I still get great gas mileage and the mechanics who change my oil say the engine is in great condition. Love this product!!
