Do I have to modify my diesel to use Bio-Diesel?
NO. However Bio Diesel does clean out fuel tanks, lines, pumps, and injectors because it is highly detergent. It may clog fuel filters if you have an older diesel or if you have not changed your fuel filter on a regular basis.
It should also be noted that Bio-Diesel at blends above B20 (20%) should not be used when you are expected to be in tempatures less than 45 degrees F.
