Dunno if this is universally the case, but the heating oil sold in the Atlanta area
is #2 diesel. I expect that's the case pretty much everywhere, since there was some
talk a few years ago about dying one of them red to try to catch people who avoid
road taxes by filling up their cars from the heating oil tank.

I expect the VW quit at higher temperatures simply because the fuel lines for the
heaters are larger than those in the car.
