Home Heating oil will be technically fine, if it s #2. #2 heating oil & #2 diesel are the same thing. There are a couple downsides. Home heating oil does not have to be nearly as clean as Our fuel- If the fuel is not as clean you may get some filter plugging issues. Also, Home heating oil & agriculture Diesel are both Dyed a Pink color. This is to denote it as fuel that has not had road tax payed on it. If a law enforcement officer checks your fuel, sees the pink color, you will be subjust to a fairly large fine. As a side note, if you do this, it will take several tanks of pump diesel to get that pink color out of your system. P.
