Re: [MBZ] Absolutely pathetic fuel "economy"

First, unless you've fixed it already, it's somewhat likely the 
odometer is slipping and not recording the milage correctly.

Second, you very likely have a worn timing chain unless it's been 
replaced.

Fix the odometer, replace the timing chain, do a valve adjust (or valve 
job if the valves aren't tight in the guides, you're about due for one 
of those, too), and you will be back up in the correct milage range.
