C200 Petrol (UK) MPG
I've just 700 miles on my S205 now and while MPG is improving as it runs in, I still find it quite a lot lower than I expected.
I never expected quoted figures of high 30's/40's/50's but I'm struggling to get above 25mpg knocking about/short (<10miles) runs from cold (auto, driving smoothly) and 35mpg on a lengthy motorway run.
I'm hopeful that this will improve as the engine runs in but at the moment its doing the same MPG as my BMW z4, 6cyl 3.0 twin turbo (admittedly with 30K miles).
As yours is petrol I imagine it'll be a lot worse.
I gave up worrying about mpg and just enjoyed driving it.... When it all works ok.
I get high 20's / low 30's mpg pottering around town. Usually 45 mpg on longer distance. When I go into the office, there's a 20 mile stretch with 50mph average cameras and I always get 45mpg for that.
Last week I did London to Newcastle and back (mix of 75mph and 50mph temp) and got an average of 45mpg. Reasonably happy with it (especially as my employer pays 45p/mile!). Managed to get 80 or so 'extra' miles each way by being gentle with the right foot.
I drive around almost always in comfort but occasionally switch to sport if I'm joining a motorway or dual carriageway. At motorway speeds with Distronic active, switching to Eco didn't seem to make any difference (same 2,000 RPM at 74 mph). I haven't used it much but I think Eco just numbs the throttle response and speeds up gear changes.
I disable stop/start if I'm in stop/go traffic as it's not often 'off' for long enough to get any benefit. I leave it on for things like red lights and level crossings though.
I'm on 17' tyres if that makes any difference (probably minimal).

I'd expect the diesel to be more efficient, but I don't do the miles for one, nor did I like the noise it made. The petrol, while not completely silent, is certainly very quiet.
My post is more about the rather wildly differing values from the expected level, what I'm seeing and what others see on the same engine as mileage increases and the engine free's up a bit.

Oh I did like that bit on the start of your post ' I've done 1,800 MPG since taking delivery.' Fab!

Anyhow so we don't get off topic, I'd be interested to hear other experiences of running in vs mpg.

Are these cars supposed to do about 50mpg on the combined cycle? That is a laughable figure really.
Most 2 litre cars of old would be supposed to get about 30mpg on the combined cycle. My Audi A4 and Civic Type R were supposed to, and both achieved it. It seems newer cars get the same figures in reality, with only the quoted book figures going up.

The Best of Mercedes & AMG
That's measured with the computer and reset each time I fill up with petrol.
My daily drive is a couple of miles of urban roads followed by around 15 miles of motorway, each way.
Nowhere near the Mercedes claimed figures but then again, I never expected to see those!
