Lower Winter MPG????
Is anyone else experiencing lower mileage during this subzero weather? I seem to be getting 19-20 overall but its mostly city driving.

I know it doesn't get cold down here in Houston, but I've alway been told to use Stanadyne diesel fuel additive. Here is a link if you want to know more about it. http://www.stanadyne.com/new/ppt/ppt_dfa.asp It should help with your cold weather starts. I usually put it in about once a month, but have been told by my brother who ones a diesel truck and 18 wheeler to put it in every time I fill up.

On my last fill-up I got an amazing 17mpg....
 Part of that was that I got stuck in the snow for about an hour a little over a week ago, lots of rev'ing and idling trying to get out (finally did), lots of idling warming the car up (we haven't seen above 20 degrees in over 3.5 weeks so far...most of the time its in the teens) I know its my fault....when its warm out I usually get about 22-23, if I do all 55mph driving in the summer I can see as high as 30.2 (my record so far)

Several factors affect winter mileage. First and foremost is winter diesel fuel has a lower BTU content than standard summer diesel fuel. Then you have the extra warm up energy it takes to get the car up to temp. The colder denser air helps your engines efficiency but increases aerodynamic drag.

my experience is a dramatic decrease in fuel efficiency. in round numbers 30 mpg in the summer. the winter mileage is low to mid 20's. say 22 or 23 mpg. driving type/conditions basically the same whether warm or cold. this is across the 'fleet'. two 123's. one a 4 cylinder manual. one a 5 cylinder. two 126's. one a 5 cylinder. one a 6.
