I was more interested in using biofuel for home heating oil. We've already cut back to only using our G6 for transportation,my other cars sit. I use maybe 7 gallons of gas for mowing the lawn, so my major expense is the roughly 900 gal. of fuel for heat, and that's with a new high effiency boiler. Last years oil cost about $2700 and the projected price for this year is well over $ 4000.This kind of money means heat or eat,but not both. The whole point to this is that if I have to go broke buying fuel, I'd rather do it by purchasing something that could help the economy and not further screw things up with petroleum. Now if we take all diesel vehicles, and homes burning oil and supplied them with bio,how many barrels of oil would be saved for use where there is no substitute as of yet? I believe it would reduce the need to import by half if not more. Try and remember that the amount of petroleum in the world is finite,sooner or later it will be gone. Bio on the other hand is not, it is an entirely renewable source. I really wish I had the wherewithal to get into this business,as I think there is a very lucrative future in it. Hank
