I have been using Pennzoil for over 40 years in my cars and trucks and remain very satisfied with the quality. It is an excellent value. I usually keep my vehicles for 10 plus years and it has served me well, even with my high mileage vehicles.

I only used Pennzoil conventional in my Rx-8 - the mechanics that worked on it always commented how clean the components were. It's the only oil I know I can trust!

Just had my oil changed before I made a 1500+ mile journey and of course we used Pennzoil!! The mechanic gave me a really cool Pennzoil sticker too! Everyone in my fb Joey Logano group wants the sticker now!

I've used Pennzoil oil forna long time in ally vehicles. I've never been disappointed in the product, and it has great protection properties. After tear downs, the engines look great.
