I was not involved with any of the technical or manufacturing process. During the first part of my career I did have the chance to visit the original Pennzoil refinery in Oil City, PA, and made several trips to the Pennzoil refinery, blending, and packaging plant in Shreveport, LA., and almost on a monthly basis I went to the R&D Lab in The Woodlands, TX. After Pennzoil bought Quaker State, I never had an opportunity to visit any of the Quaker State facilities. I have been to the Shell refinery, blending and packaging plant in Port Arthur, TX., and made many trips to the Shell R&D center in Southwest Houston. Except for my short stint with the Racing Division of Pennzoil, I spent my entire career in the marketing of the brand. And believe me, sometimes that was very challenging with some of the [censored] the marketing department in Houston came up with, especially after Pennzoil bought Quaker State.
