there is no difference
in the octane so-to-speak..It's in the dye.. If it's colored red when Johnny stabs a stick in your truck or car tank in CT, then you'll have a problem. I don't know about other states, but thats Connecticuts guides.Other than that, you can use heating oil, kerosene, dyed diesel or regular diesel.. Their all at about the same grade of fuel and your deisel motor will always run.
