[This review was collected as part of a promotion.] This oil has brought my car back to life and I am very happy with its performance. I am comfortable at knowing my engine is protected and the seals are ok by its great additives that it has for the higher mileage engine that I have! 200k and still going strong!

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.

I have used the Pennzoil high mileage for a few years now and don't want to try another. I have gone over my limit in oil changes a few times and still looks great when I drain it. My truck runs smooth and doesn't miss a beat. And for 237000 miles it's saying a lot! Would absolutely reccomend high mileage for any vehicle. I wouldn't use any other.

[This review was collected as part of a promotion.] When it comes to our car, we care about what we are putting in it. We want it to outlast its life expectancy. We can only do that by ensuring we give it the very best products. We choose Pennzoil products to help make that happen. A couple of years ago we switched to high mileage. Our vehicle runs just as good today as it did the first day we started it up, 13 years ago. Do your vehicle a favor and treat it kindly, it will be kind to you!

I have a 97 ford ranger and got it from my dad when he passed. It's a high mileage truck but since switching to penzoil high mileage my dads truck has another 100,000 miles or more thanks to penzoil. It's all I have that my dad left me and he was a huge nascar fan loved ford and Joey is a great driver to have on fords team

I have a 2002 Chevy Tahoe with 259,328 miles on it. It burned about a quart every 1,500 miles. Every since I switched to this high mileage oil I have not lost any oil in about a 3,000 mile period. I’m actually going to make it through a oil change interval without adding oil....

[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.] My grandpa has always used pennzoil he's finally made me switch sides. I've put it in my last 4 cars and never had a problem. Always changed around 4,000 miles. And looks almost as good as it did when I put it in

The bottom line here is that oil additives aren’t going to fix leaks. You’ll have to get those old seals replaced eventually. I wouldn’t pay a premium for high mileage oil, but if you have an old, abused engine and can get the oil at a good price, it won’t do any harm.

[This review was collected as part of a promotion.] My father is the owner/curator of a historic auto racing museum in Pawtucket Rhode Island. Not only am I his son, but I am a volunteer at the museum. When we go to races, car shows, and events all over the north east, we have an old Snap On Tools truck that was painted, gutted, and set up to be a museum on wheels. We cannot fit all 8000 square feet of museum artifacts in this truck, but we put different things on the walls and display cases that coinside with whatever race or event we were invited to, and people walk through the truck starting at the back, and exit out the front..This truck gets MANY miles put on it between the months of March and October, and Penzoils High Mileage oil is perfect to keep this truck running each and every race season...It would be absolutely amazing to win this toolbox and add it to the museums collection of priceless artifacts..We are a non profit organization, and if you would be interested and we were chose to receive this awesome gift, we would also be interested in working with Penzoil to promote racing history and at the same time we can promote Penzoil at the many shows we attend..Thank you, and from all of us at the Pronyne Motorsports Museum, Merry Christmas!!!
