Aw Jeesh! I already boycott Exxon because they are a bunch of slimebuckets that polluted Alaska and then didn't have the gonads to face up to it and to this day are trying to litigate the thing to death. Then, they merged with Mobil, so I boycott them, also...then, you should avoid Citgo because of Hugo Chavez...now, this... and Chevron is the same as Texaco, so who is left? Fina? Shell? Racetrac?
Fina is a French owned company, so probably should be boycotting them too. Shell is Dutch, (Royal Dutch Shell) and get much of their oil from the North Sea fields. , so they are OK. Unfortunately in my town they are generally on the high side, due more to their locations than a general trend in that part of Texas. (For example the Shell near by daughter's in Austin is always a little less than the Chevron next to it) And in my town there essentially isn't anything else, but the "off brands". We have 7-11 (Citgo), Shell, Chevron (w/the most locations) Texaco (took over the local Racetracks), and HEB (Local Texas grocery chain. Only one of 3 WalMarts even has gas, and I wouldn't put that or the HEB in YOUR car, let alone mine.
The plain fact is the most of our oil comes from overseas, little of it with what you'd call friendly suppliers. The Saudi Princes and others are using the petrodollars to fianance the Jihaies.
So in so far as we continue to burn that foreign glop, we are supporting those who want to kill us.
Maybe if you've got a BP station around... I'm not sure where they get their stuff, probably Saudi, but maybe the North Sea.
