[This review was collected as part of a promotion.] I bought this product for my Chevy Truck and 200,000+ miles later the motors still running strong and my malibu 185,000 still good

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.

I only use Pennzoil High Mileage oil in my car, it is 16 years old now with high mileage and it gives me peace of mind knowing that Pennzoil is protecting my car.

i have been using penzoil since i could open a hood.i use it in all my trucks,like my father did .it extends the life of my 36 year old ford motor ,i never have a concern about it not starting thanks to penzoil

This high mileage oil rocks. It does not break down in the extreme heat. We have 2 older high mileage vehicles and this oil is pretty clean between oil changes.

I use high mileage in my 2001 Chevy caviler.The miles are 149,000 .I feel it gives the best protection a n d peace of mind.I have been using Pennzoil since EDDIE Hill was Drag racing

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.

I travel long trips every month for work. I have racked up almost 60k this month alone. This high milage oil gives me confidence to keep going month after month.

i trust Pennzoil over almost anything I can think of. I just do not understand advertising the 20 weight oil for autos over 75,000 miles. With that much engine wear, I want something with a t least a 30 weight. I am not talking 10 W 30 either.

I've been using this Pennzoil High Mileage oil in all 3 of my trucks for as long as I can remember! This works perfectly for me as my trucks are all at approximately 100k miles. And still going strong thanks to Pennzoil
