There are some other important differences in the way they burn, mostly that kerosene burns hotter. and cleaner than fuel oil so the equipment has to be built to handle that higher flame and heat box heat.

Heating oil/#2 fuel oil is that same as diesel fuel used in vehicles but without the road tax applied. Fuel oil will be dyed red for identification while diesel will not be and will have a yellow/green tint to it.

Kerosene costs more but also give off more heat per unit. You may be paying more per gallon but it can be negated by more heat per gallon.

The different fuels are similar but not completely interchangeable, But it is a good idea to talk to a burner specialist to know the specifics of your equipment. Ran out of heating oil and picked up 10 gallons of diesel to get your through until the next delivery? You're probably going to be fine, but "probably" isn't always worth the potential risk(s) so it's good to actually know.
