CB, perhaps you were writing figuratively, but I don't think biodiesel will have ethanol as a component. <it's biodiesel from soybeans, thinned with ethanol from switch grass>

Gasoline and ethanol mix fairly well, but diesel and ethanol are not ideal blend components, though 20 years ago I was suggesting to BP that such a blend would be worth considering, as an emulsion, with water, a surfactant and maybe an ignition improver. Made with olive oil or other oils, and lecithin as a surfactant, it could double as fuel for the driver as well.

Ethanol would best be used as a gasoline replacement in cars. Soybean [and other plant oils] should probably be mixed with methanol from natural gas to make nice esters rather than gummy vegetable oils which lack oxidation stability [and I don't know what their cetane numbers are].

I'm out of date these days, so don't know where the economics and technology are driving diesel fuels, but that's my guess.
