Back in the day kerosene/no. 1 diesel was the preferred fuel for large, stationary diesel generator sets, say from 50KW to 1500KW. These sets may have large fuel tanks that hold up to thousands of gallons. The thinking was that for long term storage of possibly several years with only periodic maintenance runs, the kerosene/no.1 diesel would hold up better and have less algae.
However, in recent years some of the major engine manufacturers have made noises that they would not honor the engines' warranty if anything but no.2 diesel were used. Check your owner's manual.
As for me, I buy no. 2 road diesel 5 gallons at a time. I like to find a pump station where I can get both gas and diesel at the same pump station. I find the off-road diesel pump stations are outback and inconvenient or some guy with a 500 gallon tank is in line ahead of me.
