I do really thank all of you for your impressive advice and comments!!!

I have a table about M.B. 6-cylinder engine data on W124s:

ENGINE - YEARS MANUFACTURED & W124 MODEL FITTED

M103.940 - 1987-1991 206 E, 300E 2.6
M103.983 - 1986-1992 300E, 300TE / 1988-1989 300CE
M103.985 - 1990-1992 300E and 300TE 4matic

M104.980 - 190-1992 300CE
M104.942 - 1993 300E 2.8
M104.992 - 1993 300E/CE/TE / 1994-1995 E320 (sedan/T/C/A -cabriolet-)

ENGINE MANAGEMENT SYSTEM:

All M103s and M104.980 - CSI-E (Contininouos Injection System - Electronic)

M104.942/92 - HFM-SFI (Hot Film Management - Sequential Fuil Injection)


********************************

The 1993 300TE-24 in question does not have ASR nor cruise control. It is well equipped for an euro-spec model (it has power seat, fully automic A/C -which I don't like, I prefer the manual A/C unit, power windows and locks, roof rack and a 4-speed auto transmission).

Is it true that the M104.980 is considerable more of a gas guzzler than the M104.992?

Again, thanks to everyone for your advise.
