[This review was collected as part of a promotion.] I put this in my truck then went back and forth to work and did a lot of wheelin on the weekends for little over 8months when I changed it is wasn't like conventional oil it was still clearish and smelt great

[This review was collected as part of a promotion.] I used Penzoil in my new car that I purchased in 2002. When the mileage rolled past 100,000 naturally I switched to the Penzoil formulated for high mileage engines. I sold that car to my niece with over 300,000 miles on it and she still drives it every day. Enough said.

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.

I found that using this oil in my 1997 Camaro works the best. I tried every other hi mileage motor oils and no other stacks up to this one! The whole engine runs very smooth and it really quieted my valve train down. This oil is best for my ride I wouldn't trust anything else.

[This review was collected as part of a promotion.] My last 6 oil changes have been with Pennzoil High Mileage, my Mustang now has over 168,000 miles, and I am very pleased with the results. I have had no problems, oil related. I have thought of going synthetic but I believe I am getting great results as I am losing less oil and each oil change looks a little cleaner than the previous one.

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.] Owning an older model car means taking extra care for it as it ages. This includes oil changes. While I tend to lack on changes frequency, I know with Penzoil High Mileage, I can go the extra mile. It delivers every time. My old truck is a hard worker, and this oil can take the abuse. Reach for it, I do.

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
