...and no, the EPA regs that single out compression ignition engines specificallly prohibit biodiesel, WVO, vegetable oil, and even HYDROGEN fueled engines (how do you spell "#@it for brains" which I understand is a Military term)? So you can kiss your dreams of getting an engine delivered through a loophole goodbye. However, our friend John Ferguson up Canadia-way is presently sitting in the catbird seat 'cause he's not subject to the evil EPA, who will be among the first group up against the wall when the Revolution comes. So buy one from him and when you return through your chosen port of entry, when they ask you what that shiny new green diesel engine is doing in the back of your pickup, you can just respond innocently with, "Oh, I just carry it around."
