The MPG Game
On the way to work this morning I was getting really good MPG in my 2007 E350 4Matic:
.....and I wasn't even driving like Ms. Daisy. Pretty sweet for "city driving". Must have been a lot of water vapor in the air or something ;-)
So what's the best you've been able to get?

I do not show that same number but this is over the trip home from a school competition. Most of the drive was at 75MPH or so but there was a "parking lot" during the rush to exit the event that had me sitting at under 5MPH for a good 15 minutes. (Before finally getting onto the highway)
This is in my 2004 E500 - shows you that even that large V8 is not that much of a gas hog even when driving relatively fast.

I can easily get into the 30's - middle 30's if I try. I'd rather get to my destination sooner. Two buddies and I drove to the World Series in Oct, watched the game, turned around and drove back. Trip there I drove as fast as I could (lots of tripple digit cruising); think I averaged 78 MPH. Trip back was at night after the game staying awake was the main objective - cruise was set at a reasonable speed and lots of stops were make to walk and wake up a bit.

Something interesting I'm seeing.... Comfort Mode versus Sport Mode seems to be a negligible factor, and driving conditions and "method" are, as always, key to getting good MPG. Now I still waffle between C and S.... but that's another thread! :-)

Obviously the engine also makes a big impact. I would expect the CDI to walk all over an E500, for example.
My E500 has big enough final drive ratio that it is very happy cruising at 80+ without using much fuel.

That 7th gear sure makes a difference. At 70mph my 5-speed does about 2200RPM, while your 7-speed does just about 1800RPM at 75mph. Quite a significant improvement MPG-wise. Plus, lack of 4-Matic only helps the fuel economy.

I can barely resist the urge... "...closer to NYC".... MPG goes to crap.... There are a pile of jokes in there. ;-)

Very recently, while tuning my suspension for comfort (mines a diesel), I reduced air pressure on my low profile tires from 38/40 F/B to 36/38 then noticed an increase in tank mpg from 26.9 to 28.9. I don't normally bother with mpg but this was very interesting especially when the reverse should be true; perhaps someone can explain the science behind it.

This is much more noticeable in bicycles but it also is true in cars. The less energy loss due to vertical motion, the better. Either a smoother road or softer tires or a "softer" suspension. This is why it is so helpful to have lower weight wheels as it reduces the energy needed to move the wheels over small road imperfections that the tires do not absorb. (It also helps reduce rotational inertia which helps in acceleration, but that is another topic)

THE C350
When I checked the mileage on this tank after some city driving the average was 37.1!! I drove it for another 200 or so miles before filling it up.
This was the same tank as above but notice I had driven 400 miles and had 398 of range left!! I will say that was driving about 62MPH behind a truck (earlier on the tank I had been going 70+) but that is just amazing for such a heavy car!!

We just took the CDI from Washington DC to St Louis and back in a weekend. Around 800 miles each way. We averaged 35mpg cruising around 80 the entire way. Can't wait for a tune on the car...get that number up to 40mpg.

The worst I remember was 2 gallons (of diesel) to a mile, doing 36 knots crossing the English Channel on my way from Port Solent Marina in Portsmouth Hants, to Cherbourg in France (in my Motor Cruiser)

I've been averaging 26.9 mpg for the last 10,000 miles on my E550. I routinely click off 28-29 mpg on my commute (150 miles r/t) with a high of 30.5. The only thing I've done to the car is lower it about 1.5" which appeared to help both looks and mileage. One thing I do notice is my best mileage occurs when the outside air is in the 80s when it is thinnest without needing the A/C on. I still blast the on ramps and interchanges but smoothness really counts when cruising.
