Fuel Consumption C200K

[derek/f200]

What sort of fuel consumption should I expect from my recently aquired C200K. I have been rather disappointed with my present figures of 19-22mpg for urban driving.Is this normal for this car or can this be improved? The car has 40,000 on the clock and has had one major service.

unless you have a very heavy right foot i would think that you should be getting more to the gallon than you say, - I have a 1992 190E with the 2.6 engine admittadly I have a light right foot but I am getting 28 / 30mpg around town and 32 / 35mpg on a run at a constant 65mph. I hope that these figures will give you something to work from.

Hi

You should be getting more than that i am sure. I have an S280 and get more than that and i am not known for taking it steady!! I am getting about 20 round town and 28 on a motorway. 24 overall, and this thing weighs 2000kg....

Hope this helps

These are really impossible to answer. If you mean that trundling along a clear flat A road at a constant 40 for 20 mins you are getting 19-22 then no its way off.

However, if you mean that your daily commute is 5 miles each way between 8:15am and 9am and then again at 5:30pm - 6pm then it could well be right.
My 270 Diesel will do 45-50 on a run. However, get her in traffic, over short journeys to the shops and back, then add in the quick 90mph blast down the local dual carriageway to Sainsburys at she will happily report less than 23mpg. Its all down to how long you spend stationary, how hard you accelerate and how long the car spends at a constant speed. I once clocked 13mpg on my E240 on a particularly nasty journey home. I rarely saw more than 19 on my 4 mile commute, but the same car would return 36 on a run to London and back. Apples and Oranges.

Get her on a motorway, reset the computer to zero and then run her for a few miles at 50, 70 etc. Judge your mpg on that.

Ah,I love computers (NOT). As Jberks (dam, blast an all that) I find myself agreeing again.

However - have you calculated the consumption the old way? I.e. Fill her up at start of week then reset trip, then fill her back up at the end of the week and record the miles, quantity of fuel used and do the math's.

I have and found the comp on my car is within a mile or two. So give this a go also.

Hi my wife has the c200k and it is used mostly for shopping and just generally knocking around the doors and it is averaging 30/32 mpg,I would suggest changing the air filter if it`s only been serviced once,cheap job can be done in two minutes at a cost of £8 odds.well worth a try.

The air filter advice is good and certainly worth a go, however I would question 30/32 knocking around town. MB official figures are normally pretty close and given marketing requirements are going to be optomistic if anything.
According to the MB site, a C200k Coupe manual will do 25.9 urban (23.3 for the auto). Certainly a combined figure of 33-35 may be realistic but my experience with the 240 was that I could achieve the combined figure only if over 50% of my 10 mile journey was at a constant 50-60 in light traffic and I wasn't actually stationary at any time. Less than 10 miles or any hold ups and forget it so not a hope if I went anywhere near the city centre or within 50 miles of London.

As J berks says every case is individual, one of my cars averaged 26 in herts,
down here in Dorset it does 21. If there was much wrong with the car it would be running rich as the eccess fuel has to go somewhere, black exhaust.

This time of year has got to be the worst for taking fuel readings. As the weather warms you should get a more realistic idea, you can then add the winter and summer figs together to get a mean of ave consumption.

A lot of cars that do relatively short journeys at this time of year don't get to their optimum running temperature. The manufacturers figures probably come from tests with hot engines which will make quite a difference.

I used to hate winter when I was running bigger petrol engined cars, consumption was affected dramatically, anything up to 25% worse.

Thanks for all your views and advice.I have changed the air filter and there is a slight improvement.

My c230k gave 28mpg, fully laden with a roof box and nearly on the rear bump stops, on the way back from Germany, 90-110mph alot of the time.
Not bad
