[This review was collected as part of a promotion.] I have used the Pennzoil high mileage oil for quite sometime now. I ran it in my old GMC pickup truck which had well over 300K on it and it ran so smooth when I used this fine product of Pennzoil! I'm a believer!!!

[This review was collected as part of a promotion.] I used Pennzoil when I bought a 1974 VW Beetle...so I kept using it on my 1994 Pontiac Grand Prix...now my son NEW car...Pennzoil keep it running all these years...who knows if my youngest son would also used it in a bear future...

[This review was collected as part of a promotion.] When I was young, my father told me Pennzoil was the only oil he'd use in any of his cars because they offer a specifically designed oil for each stage in the life of your vehicle. To this day I still trust Pennzoil to keep my vehicles running in fact just did and oil change for my 1994 Silverado which has 222000 miles on it now and still sounds as good as the day I bought it . Thank you Pennzoil.

[This review was collected as part of a promotion.] We have 3 cars, 2 of which are 20+ years old and still daily drivers. My Buick land yacht has nearly 300,000 miles on it and still runs like clockwork. I like to partially attribute that to Pennzoil High Mileage. It is the ONLY oil that goes into my classic car.....

We always use Pennzoil in our cars- and the high mileage is good for all of them, but especially in my 2001 Dodge Ram pickup. We own other cars- a 1987 Buick Grand National, fully restored, a 2007 Mustang GT, and a Jeep. But I always find myself running the Ram- it's reliable, and I feel safe in a big ole truck. It's got almost 200k miles on, and it hums right along. Keeping the oil changed is the KEY to having a vehicle last!

[This review was collected as part of a promotion.] I only use this oil on my ford explorer 200K+ for milage and every time I change the oil it runs better every time and every day. I tell my friends to use it and they have converted from their perfered to this for everything.

I purchased Pennzoil Platinum for a old honda odyssey that had about 130k miles on it. Due to less than stellar maintenance there was some deposit build up and when I switched to platinum it cleaned out all the junk quickly but left the old seals now exposed and likely more brittle than they should have benn. Anyway after the cleaning the seals started leaking to the tune of about 5 or 6 nice drops each night. I replaced the v tech seal and it stopped that leak but the oil pump leak continued. I switched to pennzoil high mileage and after only a few weeks it has slowed to only 1 drop every 5 days or so and I suspect it will stop all together. Please understand platinum simply cleaned out the junk leaving the old seals that had been hidden dry behind junk to leak but thats not platinums fault its the fault of the lesser oil and longer change interval that was used previously. long story shorter pennzoil high mileage slowed and will likely stopped a leak for me.

[This review was collected as part of a promotion.] I have been using the high mileage in my tahoe for about 5 years now. After the first oil change I noticed the oil was not as dirty as before, so that means it is doing a better job than the Castrol that I used to put in. I am penny oil for life

I have been using Penzoil High Milage in my 2004 Ford F-150 ever since I bought it used with 198,000 miles. I am up to 229,000 miles now. I have not experienced any lubrication issues and will continue to use this product until she gives up the ghost.

[This review was collected as part of a promotion.] I usually carry 2 quarts in my car because my Prius eats oil weekly. Every 600-1200 miles I'm down at least two quarts so I depend on Penzoil High Mileage to get to the next change. I'll be dropping a new engine in it soon but Illalways use Penzoil.
