[This review was collected as part of a promotion.] Began using Pennzoil High Mileage oil in my 1988 S10 when it reached 145k now with 215k it's still running fine. Go Pennzoil.

[This review was collected as part of a promotion.] For years now I have used this product, and it does what it is advertised to do. Works well on the older, high mileage engines I have owned.

Great Price

Good value

Have been using this product since my car turned 100,000 miles ,used regular Pennzoil before then and wouldn't use anything else!!!

I use this is in my explorer. Its a 97 and has some miles on it. My vehicle runs much better very happy with it

I use this on my sons Hyundai with over 135,000 miles on it. Doesn't burn a drop between changes and doesn't smoke any either. Cheap insurance.

[This review was collected as part of a promotion.] Always use this for the best performance ! It really does what it says !

I have a 2000 Chrysler Town and Country with 240,000 miles. I use this to help get a little more from it
