At last, a question on here that I can give an answer to. been around the stuff for twenty years,and can tell you that there is a difference in fuels, just not what the companies want you to believe. kerosene and #1 clear fuel are the same.#2 road fuel is the same as #2 red (ruby) just without the dye. both #2 fuels from our company have additives that decrease gelling tempertures ,increase cetane ratings and add a certain amount of lubricity . it is true that off road fuel is used for home heating and vice versa, only difference is the taxes paid. with that being said , you should not be caught with a dyed fuel in your road tractor or diesel dually, Uncle Sam frowns upon that ,and will make you regret it if caught.
