Never heard of that one, but I'll go with it. I'd like to know what diesel is different from regular diesel. All of the years that I worked on cranes and hugh fuckin diesel engines, I've never heard that. I know that red is offroad and green is onroad. They're just dyed different colors. Offroad doesn't get road tax added on. If they make a different diesel, then why do some heavy equipment come with fuel system warmers? Learn me somethin.
