In case you were wondering...

The version of your car ('92 300SD -- W140 chassis) with the six cylinder
3.5L turbodiesel* engine is capable of getting up to 27-28 mpg on the
highway.

*Unfortunately, it's also one of the few fatally flawed diesel engines
Mercedes ever produced -- the infamous "rod-bender".  The 300SD/S350 with a
factory repaired version of this engine is supposed to be a wonderful car.
