Default diesel fuel in a home fuel oil furnace?

I'm pretty sure that here in Taxachusetts there's some kind of
flourescent dye added to heating oil which can be spotted when a diesel
road vehicle is inspected if the owners have been "cheating" the tax man
by running it on heating oil..


Not fluorescent, just red dye and it's the same across the US. Heating
oil / off-road diesel gets red dye to indicate it is not taxed and not
allowed to be used in on-road vehicles, and on-road diesel is taxed and
has no dye (clear to yellow). Other than the tax and dye, they are
essentially both #2 diesel fuel, and the formula on both is adjusted in
the winter in colder areas to reduce gelling.
