Out here in the L.A. area we only have a few refineries. The gas that is sold to the independents comes from these refineries. They buy on the spot market and get it from whomever has the best price. So if you buy from an independent distributor, it could be Shell, Mobil/Exxon, Chevron/Texaco, Arco/BP, even Ultramar on any given day. If Evangelist Pat Robertson can get EPA approval, the old Powerine Refinery in Santa Fe Springs may open up again under the CENCO name providing another source. Yep. His organization owns a major share of that facility
Of course lately the price has been about two bucks for the cheap stuff for a while now, no matter where you get it.
Let the SUV drivers worry about the price!
