I no longer buy CITGO as it's a wholy owned company by the Venezula government who openly "hates" the US.

I have found through research (past threads) that BP appears to use the least foreign oil (at least on the East Coast) of any of the major and available brands in my area. Also with the BP card you get a 5% rebate on all gasoline.

My TCH makes more of a "less foreign oil" statement than an "ecological" statement. I can't help to some extent, but I want to limit the support I give to the terrorist backing nations as much as possible. Other than riding a bike BP seems to do this for me.
