It lasts longer and keeps my engine running smoothly. I won't get an oil change if they don't have Pennzoil High Mileage.

We use this oil and other Pennzoil products on our 1979 Ford and it's never ran better! Always recommend Pennzoil!

I have been using this oil since I passed 100,000 milles. No problems, I hope that it takes me to 500,000 miles. HALF-WAY THERE!!!

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!!

[This review was collected as part of a promotion.] I've always used Pennzoil in all my vehicles. Always been dependable.

[This review was collected as part of a promotion.] if it is not pennzoil it is not oil.this is the best ever oil for vehicles.

[This review was collected as part of a promotion.] I use this in my car and it works great I love Pennzoil products

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

[This review was collected as part of a promotion.] Used it in last car and vehicle was still going strong after 215 thousand miles!!

I currently use your awesome products in both my vehicles. Both are pushing 200k miles. And they both run like there's no tomorrow. Go team Penske
