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

I run the high mileage formula in all my vehicles, since I have no idea what under 150,000 miles is like.. but I have never had a single oil related damage or issues, in the 8+ years i have been using it. and I must admit I occasionally go further than the recommended change mileage.

[This review was collected as part of a promotion.] We own four very high mileage used cars because three of us travel an hour to work. My Grandson, Junior Ankiewicz, who does dirt track racing, told me to use Penzoil high mileage oil. Smart Boy! Keeps the old cars running!

my car is approaching the 20 year mark so a few years ago i started to switch to the pennzoil high mileage oil in order to save my engine a little bit from the wear and tear from me driving. before I made the switch my car would make a griding noise at points coming from somewhere in the engine. nothing too serious sounding, but since i made the switch it has been nothing but smooth rides for me and my Pontiac

[This review was collected as part of a promotion.] I have used this oil when I rebuild engines and the engines just keep on going. I have a few that are over 250k miles on them and they are still reliable and not burning any engine oil at all. I will continue to use this oil!

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!

[This review was collected as part of a promotion.] I drove a 2002 VW Beetle until 2012... it's had over 200k miles on it, I barely took care of it but I put high mileage oil in it from Pennzoil. I truly believe without this oil, my car would have never made it that far! Extrodinary!

[This review was collected as part of a promotion.] My 1999 Jeep Cherokee 4x4 has 260,000 miles and continues to run great with this oil. I think since my husband changes the oil regularly that Pennzoil High Mileage Oil will keep it running indefinitely.

Pennzoil has been the only oil I have ever used in my trucks, and our family cars for the past 58 years of driving. My second car was a 1962 Pontiac with 385,500 miles on it, and my 1995 F250 Ford that I drive now has, 288,950 and is still going strong! So thanks for making a very good product.

[This review was collected as part of a promotion.] As a single woman, anything that keeps me away from the garage except racing is a good thing. This oil helps me to stretch my visits to the mechanic out and save time for pedicures and shopping and NASCAR races!
