<VV> Fuel milage and the cold

[jvhroberts at aol.com]

 Yep, and more basic than some people think! The density and the viscosity of air increases with decreasing temperature. Where I live, that would be about the right gas mileage drop from a hot summer day to a below freezing day. 
The other reason, which becomes less of a factor as the trips get longer, is the warm up time increases, and the amount of time the choke stays on increases.

Does colder temperatures give you worse or less gas mileage?  I have to drive my 
'63 84/pg year-round and have noticed my mileage drop from 21/22 on average to 
17/18.  Comments?  Physics reasons?  Thanks
