In lovely MA, no off-road diesel -- just passed a law - nobody can use #2 in any off road application ... well ... you can - just don't get caught! You oughtta see the fines for that one!
Back in the day everyone changed their oil & dumped it right in the diesel tank. If you get stopped nowadays, & it's any color other than blue, your screwed. Not worth it unless you either own a huge tract of land,or have a fat bankroll ... but in MA, the former is not possible without the latter ....
Diesel here I've been seeing over $3/gallon, Kero is $2.79 @ one place & $2.99 at the other place (only 2 places in the state I know of to get kero). Never knew off-road diesel existed ... out here it was #2 (same thing, different name) but now that's illegal too. Wonder why?
Don't they make enough off us???
Kero is a little bit thinner in viscosity than diesel. Out here, kero is as clear as moonshine - no additives whatsoever. Being that it's thinner, an oil burner will pee through more of it than #2, with a little less heat. I know all the northern fellas mix it with diesel in the winter for easier starting & gell-free operation.
I have a kero bullet heater (torpedo heater ... whatever ...) ... one time I tried burning diesel in it. Ran for about 10 seconds, then the fan started turning slower ... and slower ... and slower ,,, until it finally seized right up! Had to drain it all out & start over with kero ... then it was happy again.
