I understand the complexities surrounding the introduction of a 'new' fuel. As you know, biodiesel is nowhere near where it should be. One day, maybe, 100% BioD will be an option at the pump... Every pump. Until then, what does America need to do in order to get it going? Obviously, we need manufacturers to WANT to produce diesel vehicles. In order for that to happen, diesel/BioD has to be appealing enough to consumers to create a need. What is more appealing than BioD? I cannot think of any... The only downside is the lack of power, but we see how well hybrids are doing with their lesser power... Also, one web site (sustainable biodiesel alliance) says 100% BioD can be used in diesel engines 1993 and newer, most likely. However, BioDiesel.org says up to 20%, without modifications. Which is it?
