[This review was collected as part of a promotion.] My old car is still running great, so that's a pretty good testament to the products I use in it.

I always resort back to this!! Everytime I switch is when something Goes wrong with my baby! Will never use anything different!

I been using it for a while now and love it.... My van as 250,000 on it and still going, do to the use of it.....

I have been using it every since i have been able to buy cars myself and i wouldn't use anything but pennzoil in any vehicle that i own

Penzoil is the only oil I use in my 2007 Dodge Ram, and in all my lawnmower equipment. Makes everything run smooth. Great products.

[This review was collected as part of a promotion.] I needed an oil change so I bought this my car likes and runs cleaner

I have an older car with high mileage, this oil seems to last and help my car maintain quality performance

I use this stuff in my car.it started knocking 6months back.now my car runs great, and i think it will be the only oil I'll use from now on..
