I wanted to boycott the majors and wondered who the little guys were, I usually buy my gas from a gas staion called Maverick but I don't know who sells them their gas? Mike...
I don't really think there are any small independent companies any longer, that's why no one has replied. Even the small mom and pops get their fuel from the major suppliers these days. It's not a bad idea to support the little guys though, even if they do get their fuel from Exon or Chevron, someday when they have an option of suppliers they will be the first to go with the new independents...if that day ever comes.
personally, I get Citgo when I can (Venezuela) and then Diamond Shamrock tends to be the low end along with Bradley/ Sinclair. I'd love to be able to track who sells to their refiners, though.
