I'm just down 880 from you here in Santa Cruz... Where is this station? I'm coming over. On Saturday and Sunday nights on KGO radio out of San Francisco (AM 810) has a guy named Dr. Bill Watenburg. (I think from 10pm to midnight) He uses more of his brain than most people. If you call him and ask him that question, he'll give it to you straight. These stations all get their fuel from the same refineries and add their own additives to it to make it their own. Chevron adds Techroline, others add different stuff. Then they charge prices to make you believe that you get what you pay for. Gasoline stations have to maintain government standards just like antifreeze. Just go for the high octaine and be happy you're not paying $2.09 like we are down the road from you...
Those of you who live out of the bay area can listen on the internet if you'd like. Pretty interesting stuff I think. http://www.kgoam810.com/
