I have a 92 Mercury Grand Marquis that I bought this for and it smoothed out the running of the vehicle.

I use this brand and had hole in oil pan,drove my car for two days before I knew anything was wrong,kept motor alive!!

I use the long life oil in my 2002 6.0 ltr GMC Denali with 270,000 miles and still runs storm to this day.

Got an ol chev Silverado wit close to 235,000 miles on it. I use Pennzoil high mileage EVERY TIME, and she aint let me down yet!

[This review was collected as part of a promotion.] needed to do an oil change and went with this oil!

I buy ask my cats used with high miles and do all repairs myself. I wouldn't use anything other than pennzoil high milage.
