Andrew - if all the obvious mechanical drag items are ruled out (including wheel alignments and tire pressure), then the usual culprit for poor fuel economy would lead one to timing problems - either the cam or the IP could be off and have a serious effect. Even with a heavy foot and a heavy car, we routinely get 29 mpg on the 126 SD, and 31 mpg on the 124 D.

I'm still under 20 mpg (276K miles 83 300TD) and it's neither leaky
fuel lines nor a faulty odometer.  As of now I still don' have a clue
what might be causing this crppy fuel economy.  The car runs fine
otehrwise.  To make matters worse, diesel sells for more than high
test here in D.C.

think that was all of the reason for the 3-4 mpg drop I got for three tanks.

I believe my lack-o-power woes may have been a tank of bad fuel. Now that
I've ran two tanks of the usual stuff, everything is back to normal...even
without changing the filters yet. Could that be possible?
Additionally, the oldest girl child was home with the TDI Beetle. I drove it
today and was reminded how much fun they are. It goes like a scalded dog.
She claims she got 47mpg on the way home. When she takes off for the U.K.
next month, I be able to clean it up, get a timing belt done...and somehow
tell her it is going to become mom's car while she is singing and dancing
across the U.K. Girl-child will be surprised to find out she is now old
enough to get her own car when she returns. Stand by for tears.
