I didn't know that about aluminum, but wikipedia concurs:
"One of the drawbacks of methanol as a fuel is its corrosivity to some
metals, including aluminium. Methanol, although only a weak acid, attacks
the oxide coating that normally protects the aluminium from corrosion:
6CH3OH + 2Al ? 2Al3+ + 6CH3O- + 3H2
The resulting methoxide salts are soluble in methanol, so the corrosion
continues until the metal is eaten away."

Considering your cylinder head is aluminum and it is exposed to raw fuel,
methanol sounds like an exceptionally bad thing to put in your tank.
