That may be true, but it's hard to make that case when some engine manufacturers are telling them they won't honor fuel system warranties on engines used with biodiesel. > But 2% biodiesel, is that enough to do anything, good or bad?

Cynical answer: It's enough to drive up the local market for soybeans, which is probably the main goal. Less cynical answer: Small concentrations of biodiesel have been shown to increase lubricity significantly, and reduce particulates somewhat. I think the sponsors of the bill would also tell you that 2% is just a starting point.
