Hello, Fuel consumption has been driving me quite mad lately. I think that my car is using too much fuel, some say it's an ok amount for this car, some say that it isn't, but it's not worth getting into, etc. So firstly I wanted to find out what is considered normal combined mpg or l/100km for W211 E220 Wagon 5speed automatic? I'm getting around 30 mpg or 9 l/100km. But my onboard computer is showing 40 mpg or 7l/100km at the most (usually it's less).
