First, my reference states that ethanol is preferable to methanol because methanol can screw with any rubber fuel line components. Does my rig have any rubber fuel line components, or can I safely use methanol. Second, of all the reading that I've done on the topic, this is perfectly safe to run in my rig, but I wonder if I will have any problems with power, computer sensors, mileage (though at ~$.50/gallon who cares), filters, clogged injectors, etc.... It's my understanding that there is no difference in any of these issues between biodiesel and petroleum diesel, just wanted to make sure. $40K is a lot to spend on a truck, and I'd sure hate to have to put a new engine in it. Thanks for the help.
