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!

271,000 miles and it just keeps going! Original engine still internal very clean. Never opened up, but dipstick looks like new. Never babied.

[This review was collected as part of a promotion.] I have over 250,000 miles on my car and Pennzoil High Mileage is a huge part of that.

I use this in my 1996 Jeep Cherokee with over 140K and it still runs great! Pennzoil High Mileage is a reliable product.

I bought this about three months ago and my car runs great now that I'm using it! I'm so happy I bought it!

I have an older car with high mileage, this oil seems to last and help my car maintain quality performance
