winter fuel consumption

[PeterBergin at aol.com]

Mine does a little worse when it is cold, but boy does the turbo ever spool 
 up nice with that cold dense air.  I park out doors and I do warm the car  
up allot before driving.  Also I usually use 20/50 Mobile One in the  
winter.  It can be -20 here in Minnesota.  If I use a 5 or 10/30 my  mileage 
improves slightly.  Also if I burn a non-oxygenated 93 premium (no  Alcohol) I 
get 3-4 mpg better any time of the year.  Not sure what your  winter blend is 
in your state.

Every  winter my 200 becomes a gas guzzler. With the coldest winter on
my  ownership on record (global warming?) it has been the worst. It  is
approaching consumption of a 4.2 V8  in city driving. There is no  loss
of power, fuel smell, unusual exhaust, etc. VAG-COM data appears to  be
withing recommended limits.

The only observation is that when  engine is cold simultaneous clutch
disengagement/gas release while driving  with no acceleration (2nd or
3rd gear) on a horizontal road results in  noticeable RPM increase for
a fraction of a second. If accelerating it is  even more noticeable.

Has anyone seen/solved anything like  this?
