Fuel additive (anti-ice) in the C441 is critical. As all experienced pilots know and engineers worth their salt will tell you that it only takes a microscopic drop of water or ice chip to completely destroy an FCU.
If you do short haul in predominantly warm enviorons then 'avgas' will kill the 'bugs' that reside in Jet A1. Just a few litres every few weeks will kill the fungacide.
Zeke: You should have more sense, just remember your playing with the aircraft certification, next stop a coronial inquest!!
