I too buy B 100 from the local Biodiesel factory.... I noted it strange that the price of Bio went up from $2.15 a gal a year ago to $3.09 a gal. I asked why when the price of soybean oil did not go up..... ???? The guy gave some flip type answer about the other chemicals going up.... Hummmmmm I think we are being TOOK. Thank you Dean L.
