Home heating oil, not Kerosene is number #2, the only difference between number 2 heating oil and Off road diesel is a different color dye, at least here, where off road is red, Heating oil is a purple color. I would go and ask a local distributor if your still questionable on it just to ease your mind, call them they will tell you. I have run heating oil in my truck with no problems and as far as being dirtier than diesel, if you holding tank has a proper filtering setup that should be no problem.
