Or at least that's what the EPA has mandated. Well they mandated it back in 2005 because they, in their typical government alter-reality, believed that mandating some new product would magically make it appear. Problem is of the 500 million gallons that are required to be used this year there are.... 0 gallons available. That's right. None, zip, zilch, nada. There is not a single gallon in existence to be used in commercial applications. There is as much of this stuff out there to put in to your car as there is unicorns to harvest farts from.
