Cold Weather Winter Flying Q's

My Minnesota thoughts -

4) Add small amounts (couple of tablespoons or so) of isopropyl
alcohol (yellow can HEET) to the tanks as a matter if principle when
it is below freezing. You may otherwise have small amounts of
dissolved water in the fuel come out of solution as snow when the fuel
is severely chilled. Beware of fuel that has been severely chilled
since its last filtering. On a long flight, this snow can block the
fuel screens. I know, it happened to me although it was about -20 deg
F. I know of others that have had the same problem.


What is HEET? Thanks.
