Oil is fungible.
Give it up.
Give it up.
Of course it is. But revenue to Citgo isn't. At least make em sell it somewhere else and lose the retail profit.
Yup, for the most part, oil is a commodity. My car runs just as well on Shell or Chevron's 87 octane gas as it does Exxon's. All the major oil companies claim to have their magic "elixer" that makes their gas better but to me it seems to be mostly marketing.
