Just remember that MythBusters is a Southern Kalifornia production, and
if you tried that in Frostbite Falls Minisota, in the winter you would be
doing a lot of walking or rowing as the case may be. Diesel #2 doesn't
even think of gelling untill your down to 10F and Diesel #1 clear down
to -30F or lower. Frier Grease will turn solid at 40F if your not
careful.

yes, yes ,yes...nothing new here...you have to mix pump diesel into your biodiesel in northern climes
in the winter.
