> “The stations know they’re buying stolen gas,” Scarince said. “They’re fully aware the fuel is not coming from a legitimate source. There’s never any paperwork with the fuel driver, and these transactions are missing all the elements of a normal, legitimate transaction between what would be a refinery and a gas station.”

This seems like the easiest way to tackle this problem (aside from chip cards). I doubt it would take much pressure on these guys to get the market for this to dry up, or at least considerably reduce the profitability. I'd guess the gas station owners have a lot more to lose than the thieves actually stealing gas.
