[This review was collected as part of a promotion.] I started running the Pennzoil High Milage several oil changes ago And almost immediately could tell a difference in how much smoother my 85 Chevy 350 was running. This truck was my everyday work truck for many years. It was worked hard everyday pulling a trailer loaded with equipment and that took its tole on my engine. After retiring the truck I kept it to restore and keep in the family. This has brought my oil pressure up almost 10 psi and has made me change my mind on taking the motor out to overhaul it. I will now just fix some small leaks and clean it up just to see how many miles out of it now. Thank you Pennzoil for this product extending the life of my engine that is now @ 235,000 miles and figure I can get that many more at least. I will let y'all know how many that becomes. Thank again!

[This review was collected as part of a promotion.] I use the high mileage in my 72' pick-up.Could not tell you how many miles are on the truck but it runs like a new one with the high mileage PENNZOIL it does not rattle or squeak like it did before the PENNZOIL

We always use Pennzoil in our cars- and the high mileage is good for all of them, but especially in my 2001 Dodge Ram pickup. We own other cars- a 1987 Buick Grand National, fully restored, a 2007 Mustang GT, and a Jeep. But I always find myself running the Ram- it's reliable, and I feel safe in a big ole truck. It's got almost 200k miles on, and it hums right along. Keeping the oil changed is the KEY to having a vehicle last!

[This review was collected as part of a promotion.] I decided to try this on a car I used traveling for work. I started using this at 100k miles and the car kept going without any issues or smoke... So I decided to keep driving it. Eventually I sold it with 300K miles and you couldn't hear the car running, nor did it smoke.. Good stuff!

[This review was collected as part of a promotion.] This oil saved me from having to buy a car before I'm ready. I have a 2002 Toyota Camry that has 304,000 miles on it I drive 90 miles a day. I have used your oil for high mileage vehicles since the car hit 100,000 miles and I have never had problems. Thanks for helping save me money.

I can't afford brand new cars or trucks, due to fighting Cancer for past 9 years. So all my vehicles have high miles on them and I have always used Pennzoil's High Mileage Oil, to keep them maintained. Sold my last truck, a 2001 Chevy Silverado, with almost 300k miles on it, still running strong!

I bought this for my old high school ride a ponitac firebird witch I had kept in good condition, witch had 15000 miles on it and a oil changed it to this runs like brand new best oil for any car I have changed to and I plan to change my other cars to penzoil when the time comes

[This review was collected as part of a promotion.] I have been using this great oil in my bmw as soon as I bought the car. The previous owner said he had another kind of oil in it. So on my way home I stopped at my local auto part store and bought five quarts of this oil. The only oil I will use. After have the car for ten years this automobile still drives as strong as the day I bought it. I will only use this oil in every vehicle I own the rest of my lifetime. TGE GREATEST OIL MADE " MY OPINION" I FIVE THIS OIL FIVE OUT OF FIVE!!! Great product pennzoil

[This review was collected as part of a promotion.] I've had my car since 2002 and every oil change done. Pennzoil is all I used. When high mileage came out I was pumped. I'm am now half way into my automotive tech classes so when I start my own garage or start working in the field. Pennzoil is all I will recommend.

[This review was collected as part of a promotion.] Use this oil for every oil change in my 1994 Jeep YJ Wrangler 4.0 and it is always clean everytime I check the oil level. Plus with it having 149k miles, the motor runs very smooth and quiet. Even better than it did when I bought it with 136k on it.
