I got a flyer in the mail from a local petroleum distributor the other day, advertising diesel fuel made out of soybean oil. It said that this fuel is better for the engine{ lubricity}, conciderably less exhuast fumes, and no engine mods are needed. Can be used 100% pure or blended with petroleum diesel. Also the EPA regs on sulfur content and finding more fuel alternitives are pushing this along. The pure pure stuff is $2.50/ gal, a 2% or 20% blend that is most commonly used is much cheaper. Has anyone seen/used this fuel? IMO the less we can rely on Iraqi-juice the better off we will be. And help the farmers out also.
