I am trying to find out who has the best gas in my area for the long term survivability of my injectors. If I have to drive a bit and spend a few cents more per gallon I figure that it's worth it. But so far I have not come up with what I am looking for. I did find this interesting article for those of you with a chemically inclined mind. Except for a brief period in my youth, I have tried to keep my mind and chemicals separate. Some would opine that they believe otherwise. HNY to the Qheads.

If anyone knows of a decent web-based fuel rating sytem or article could you please post? I am currently burning quite a bit of Shell. On the rare occasions when I am forced into buying lesser fuel I know it almost instantly. It will miss occasionally while waiting at a stop light. As soon as I refuel it goes away. And if possible I'd rather send my cash to Hugo Chavez than to the middle east....so that may factor into it as well.
