I have a Cehevy Tahoe with over 300,000 miles. I still run 48lbs oil pressure due to Penzoil High Millage Oil. I'm sold big time!

My truck has over 100,000 miles and after I stated using this product it runs better. Does not skip anymore. Life saver!

I been using it for a while now and love it.... My van as 250,000 on it and still going, do to the use of it.....

Use it for my daughter's car cause she has 200000 miles on her car and when I'm gone all week I can depend on it

[This review was collected as part of a promotion.] i have 2100000 miles on my truck and it is the only oil i will use

[This review was collected as part of a promotion.] Use it on my 1999 ford f150 with 325,00 miles hard miles. Oil never breaks down

I use the high mileage in my jeep Cherokee and got 200,000 miles on her and she runs like a champ!!!

I have been using Pennzoil High Mileage for a while in both of my cars. I'm sure it's the reason my cars both still run like the day bought them new!
