- of course keep air restistance down, no roof rack with skis, bikes or

- let it run on an even speed (rv/m),
some additionals depend on the make you drive,

We usually get between 9 l to 10.1 l /100 km from our E500T. Would most
probably get more if we disconnected, phone, navigation, music, and most
important the AC, whid takes a lot of energy to run.
If your fuel economy suffers from using electronics (i.e radio, Phone,
GPS, etc), then you have some serious problems in the car. The
alternator turns all the time, only the AC should put a load on the car
and cause an economy drop. You can cruise all day long with the Radio
and GPS on, it will not affect the milage.
Nevertheless, when Mercedes claims it does 100 km on 8.4 - 8.6 litre, I am
convinced they turn everything off that is not essential for keeping the car
moving. In any case between 9 and 10 litres is not bad for a 5 litre V8.
As slow as you can get away with, and at a constant speed. It's
boring, but I can get really great milage in my E320 4-matic when I
take it easy. During the latest price hikes here I kept to the speed
limits and accellerated as cautiously as possible and saved a
significant number of miles per dollar. (But that's boring, so I
usually get around 21MPG...)
