I'd need another oil tank, but that isn't too expensive. For what it is
worth, my furnace guy says that warm oil burns better than cold, so if
you have the option you should put the tank in a heated space. I don't

This makes perfect sense. After all, combustion is just a redox reaction,
and like all chemical reactions has an activation energy. It follows, then,
that the colder the fuel is the more energy is wasted adding energy to it to
get it to reach the activation energy required for the reaction to occur.
Your net energy gain from your redox reaction will thus be greater the
warmer your fuel is.
