Part of the regimen has always been to toss in a jug of fuel system water

I think its still a good idea, the fuel anti-freeze is typically
methanol or isopropyl alcohol, which will get any water out better
than ethanol will.

Being topped off (full tank) before a large swing down in temps is
always the best preventative measure.
