I've been boycotting Exxon since Valdez.
There is good news on the horizon though...the answer is BIODIESEL! Diesel engines can run on it no problem. Not much help for us outboard owners but if you change your auto's over to diesels then you can afford to buy gasoline for the boat.
I'm thinking of selling the Yota and getting a used Dodge Ram w/Cummins....then go biodiesel!
Do some research....I'm sure the price of used diesel vehicles will go much higher so I think we need to act fast.
Here's one site on biodiesel:
