I am going to be running b100 in the next couple of months. Would I be better off sticking with my present 2000 24V w/78K miles or should I start looking for a 7.3L Ford? Let's try to set aside "brand loyalty" unless you have a really valid argument. Fuel will not be low quality. I will make sure that I do not cut any corners when making fuel from the first step to the last step.
