[This review was collected as part of a promotion.] Works well in my Taurus, and it is still keeping my college son mobile.

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!

Bought this multiple times for my old car and was always nice and could notice when oil changes were done

Having 130,000 miles only vehicle now, I have used this oil since reaching 80k miles, no complaints, engine still running strong

Makes a difference over some cheaper brands, it's worth a try if you have higher miles or a rougher running car

I bought this for both mine and my wife's vehicle's and and so happy that we chose the best product in our opinion !!!! Thanks !!!!

I did a comparison between pencil high mileage and valvoline high mileage, changed them both at 3000 miles and the penzoil oil was much cleaner!

My husband travels an average of 300 miles a day and this is the only oil we use because we know it helps his engine
