[This review was collected as part of a promotion.] I used this oil on my Ford Ranger with higher mileage.I believe that this oil made my engine work and run better than other oils.

I was told by my father as a small child you'll never get any better then pennzoil and still to this day when I change my oil it's the oil I grab first thing I honistly believe it's the best oil out there.

[This review was collected as part of a promotion.] I use this in my fleet of service vans. They all have over 200,000 miles on them. This stuff works wonderful in them. I keep great oil pressure and engines are clean. Love this stuff.

[This review was collected as part of a promotion.] My Jeep Cherokee has 208,000 miles on it. I've used Pennzoil High Mileage for my last two oil changes. What a difference an oil makes. I recommend it to all my friends. Way to go, Pennzoil!!

[This review was collected as part of a promotion.] I run the high mileage oil in my 1983 Mercedes Benz 300D with 250,000+ miles on it. Keeps everything working like a car with over half the mileage.

[This review was collected as part of a promotion.] I have a 93 Cherokee with 300.000 thousand miles on it, and this product has seemed to save my bacon!!!

Did alot of research and in the end, Pennzoil high milage came out on top. My truck has 123k miles. No issues. Wanted to be pro active, not reactive. And instantly on start up my truck runs smoother, and quieter. Very pleased!

I use it in my 2001 Nissan Frontier that has 248245 miles on it and is still going strong no engine ticks or anything I drove my truck from Oklahoma up to Massachusetts
