is it for off road equipment or for heating?
some times home heating burners are rated for NO1 oil but not very often.
for equipment NO2 fuel is the norm, unless your in temps well below 10F then the thinner NO1 fuel helps with starting when no block heater is around..
NO1 or NO2 heating oil, farm fuel or off road diesel are common terms for red fuel in the USA.
in my state its a $10,000 fine for running red fuel on road
