I recently went to this from conventional oil and am pleased at how well it works in high mileage vehicles. I can buy it at work with a filter cheaper than I'd pay at an oil change place to do the oil change.

My husband and I have tried every oil out there. Pennzoil High Mileage out performs all other brands...hands down. We have been using Pennzoil High Mileage for the past 5 years and will never use an other brand.

[This review was collected as part of a promotion.] I use Penzoil High Milage to extend the life of my suv. I love it because nothing is better than not having a car payment and Penzoil helps me keep it that way!

Started buying this again when I purchased a jeep. Penzzoil was all I ever used from the time I started driving until I went to work at a ford dealer. At that time I switched to motor craft.

I always run Pennzoil High Mileage in my truck. It helps keep my engine and seals in good shape so I can tow my R.V and Boat during the harsh summer months.

[This review was collected as part of a promotion.] I bought this a few weeks ago, excellent for the long commuter miles I put on my Toyota, reduced heat and werae and tear.

[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.
