[This review was collected as part of a promotion.] Great oil life! Dependable I've used Pennzoil Product for 30- yrs without any problems.

I noticed this oil does not break down and gum up engines. It holds its integrity and that was noticeable at both oil changes and engine rebuilds.

I tend to go too long between oil changes and this product has definetely helped keep my 13 year old truck on the road.

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 is a really good oil for high miles I have been using this in my car I have over 200.000 miles and going
