Dear All
I am interested in city / highway
Expected / Observed Gas consumption for the following W124 models:

1992 W124 300E M103 2.6 4D
1989 W124 300E M103 without first starting gear
1995 W124 E320 M104 4D

My personal observations:
(91 octane)
City / Highway
1) 9.5 / 8 ( going down to 7.6 for extremely long drives)
2)11.5 / 9.5
3)12.5 / 11.5 (highway seems in high range).

Also some Canadian Flavor:
Using Esso actually makes mileage worth - please confirm

Are those numbers in KM / Liter? That's really bad if it's MI / Gallon.

1991 300E - 212K and rising fast...

8 L/100Km is 29.4 MPG

10 L/100KM is 23.52 MPG

12 L/100KM is 19.6 MPG

I get 21-22mpg in my 2.6
How are you getting lower #'s on the freeway? Something is wrong here...

Sounds like
1987 is Second gear start and different transmission numbers.1992 has full 4 gears and lower 4 speed trnsfr number.
1992 is the best year overall.

1991 also has first gear start and a low rear end.
