that may be true if you burn straight veg oil, but if you
transesterify the triglyceride with alcohol you wind up with lighter
molecules and glycerin as a byproduct.  that's biodiesel, and it needs
heating or blending [b20 - 20% bio] only below about freezing only
because it has a higher 'wax point' than petrodiesel [-9c for canola
bio, -2c for soy bio].  i understand truckers that haul north-south in
winter often get caught by this too, as you can get a cheaper heavier
petro in the south that waxes up in cold weather.  when that happens,
the truck stops until the fuel thaws.

having the heater and maybe tank insulation makes you immune to that,
as long as the heat source is running...
