Yes, or K-1 (kerosene).

Yes, essentially the only differences between the #2 heating oil in your
tank and the #2 diesel at the pump are the transportation fuel taxes you
pay at the pump and the red dye they put in the non taxed heating oil.
Otherwise they are interchangeable functionally, and the heating oil is
also known as "off road diesel" since it's legal to use in off road
equipment.

It is a little more complicated than that. Diesel fuel typically is sold
as "diesel fuel" not a particular # oil. If the diesel fuel is sold in a
freezing climate a certain percentage of #1 is mixed in to minimize fuel
gelling effects.

It's a whole lot more complicated than that...

"...multifunctional diesel fuel additive packages are built around ...
dispersant/detergent technology which meets the requirements for
....injector cleanliness. ... The detergent can be combined with other
functional components such as lubricity improver, cold flow improver,
deicer, cetane improver, corrosion inhibitor and/or demulsifier to
deliver additional benefits..."

W/O the additional lubricity specifically, no modern diesel engine will
last long and the injector-cleanliness requirements as well as S limits
on road-fuels are significant factors. Underneath, yes, it's "fuel
oil", but the engine-diesel is far more sophisticated a product.
