At 5,000 miles oil is still yellow! Never a hiccup or concern with the motor on any of my vehicles (1968,1986,2001,2004). Good for any generation motor and make! I will never switch brands and I suggest it everywhere I go!

[This review was collected as part of a promotion.] I love this oil I use it in my Chevrolet Silverado that has 160000 miles on it and my truck runs great I love you pennzoil

My wifes ford escape has just over 100,000 miles and i switched to penzoil high mileage at around 80,000 miles. Best decision ever! Hardly any wear during start ups as my wife drives 60 miles a day to and from work

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

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 have a 1997 ram 1500 pickup with over 190,000 miles on it. It run great and I've never had to put a drop of oil in it between oil changes about every 4,000 miles.

[This review was collected as part of a promotion.] Switch to high mileage oil after I reach 100000 oil seem to be great and doing its job. still looked pretty clean after a 3500 mile change

I use Pennzoil high mileage formula in everything I have from new engine builds to my go karts to my daily drivers. Pennzoil will keep your engine welll lubricated!

[This review was collected as part of a promotion.] I have been using this high mileage oil in my ford focus since it hit 100000 miles. It is now over 259000 miles
