Hey fellas,
I work as a chemist for a Valero Refinery, my job is to certify the finished gasoline. We ran a bunch of different tests on the fuel. My primary test is to check the octane rating, whether we're selling 87, 89 or 91. From what I know working in the refinery is that it doesn't matter where the gasoline is coming from...whether Chevron made it, Shell, Arco or Valero. Our gasoline gets hauled to different gasoline stations not just Valero's. Furthermore, a lot of gasoline from different refineries get pooled in what we call Commuter Tanks off site. So you see t doesn't matter who made it but what does matter is the gasoline station you're getting it from. I am told that Chevron with Techron is the best additive you can put in your gas tank, followed by Shell's V-Power. I get a small discount at the Valero pump station here at work...but I still pump Chevron. Anyways, I just wanted to chime in. Thanks
