gasoline consumption








on urban freeways I tend to get 6.6l/100km (38mpg).
In 50,000km (31000 mi) since new, Mercedes Me shows avg speed of 8.7l/100km (27mpg) on mix of city and highways.
Caveat: most of my urban freeways have a speed limit of 80km/h (49.7mph) which maximises the benefits of the w213 coefficient of drag. I get 7l/100km when on 100km/h (60mph) freeways and 7.4l/100kmh on 110km/h (68mph) interstates.
fuel used has always been RON98 (AKI 93 for those in US).
tangent: I have not had any stored and current codes relating to mixture/misfires or knock in these 30k miles so I feel the fuel economy stats seem to support my view that the engine is functioning optimally.

In my city speed limits are School = 15 mph, Residential = 25 mph, Other = 30 mph to 45 mph.
I can rarely go the speed limit or higher than 5th gear on the 9g automatic transmission.
