Morons. Sierra Club is pissed because it is not their idea. Run a diesel engine on 100% biodiesel. I do, and it runs very smoothly.
These tree huggers are hopelessy lost in the '60's. They'd rather lambast the industry than support a current technology that works.
So, not sure what their real agenda is. It apparently is not environmental.
Their agenda is the destruction of capatilism and individuality. Period.
Watch out for the Bears!
