if not BP, where should you get your gas? Sierra Club says Sunoco

Just a few years ago, when BP was pushing their "Beyond Petroleum" campaign and was running a solar panel factory here in Maryland (which closed earlier this year), it seemed to many -- including me, and the Sierra Club -- that if you had to buy gasoline, BP was probably one of the least of the evils.

Well, that's clearly not true anymore. So as we head into summer road-trip season, where am I to fuel up my Subaru (the machine affectionately known as "Scooty-Puff, Sr.") now?

The Sierra Club takes an updated look at the options, and puts Sunoco at the "top of the barrel". ExxonMobil and ConocoPhillips are at the bottom, with a special Dishonorable Mention for BP.
