I realize this isn't a purely 911 question but there is nobody better to ask...
Hotlanta is about to turn really cold. We're supposed to get single digit temps tomorrow (Tuesday) night of 5F which is just crazy for us. North Alabama is supposed to have a wind chill of -30F. I don't know if I can remember this kind of cold.
The local news just said any vehicles parked outside should have a full tank of gas to keep the fuel lines from freezing. My wife and I looked at each other puzzled. I've never heard anything like that before. Can any of you folks in the great white north that are more familiar with the effects of bone-chilling cold on engines explain the logic behind that recommendation? The only thing I can think is that with less fuel in the tank there is more air. I guess any water vapor in the air in the tank would condense and mix with the gas?
P.S. While the 911 is tucked safely in the garage, my truck is outside (with a full tank of gas).
