230K Engine - How good is the economy of one...

[mbzclk]

Hi
As some of you know I have a CLK230K, I have filled a full tank plus a 15 quid topup, I am now at 290 miles and am hitting the point where the light is due to turn on.

The onboard computer says I have achieved 22.2MPG. Is it me or is this figure really low? I have driven the car fast on a few occassions but mostly very calmly and gently, this car must be quite a bit more on consumption with electric leather heated seats (heavier then normal seats) and I use some of the toys on the cold mornings such as the heated seats (15 mins) and hot air blower for about 5mins.

The gearbox is also a sequentronic that is operated by a hydrollic pump, but i was looking for about 30MPG from this beast?

Asking for a bit much or should I be getting a better figure?

Not a big issue, I can wait for all of you to see the car and give your opinions at the meet next week at Olly's (look forward to going to my first meet too, and at that a Merc meet)
Thanks all.

I average 30mpg from my 1998 c230k, mostly motorway driving though. On a sustained run 35mpg isn't unusual.

I don't have a trip computer, I always fill to the brim, note the mileage then do some quick maths.

Hi there,

I personally have found the M111 230K engine to be pretty thirsty, but if you do compare power output, it's producing similar power to the six-cylinder 280 engine - if that makes any sort of sense.

My C230K used to be pretty poor for fuel consumption, and a friend of mine has recently bought a 2001 CLK 230 Kompressor - also pretty juicy I would say.

In fact, I posted a thread about it a couple of months back:

Still a good powerplant overall - love the torque and usability of them for what they are, easy and cheap to work on as well

Thanks all.

from reading various threads on this forum and others as I was looking at buying one I have decided they are strangely thirsty and went for the 320 instead,

have had a CLK320 for about 3-4 weeks and got nearly 30 mpg bombing to work and back, mainly on dual carriageways to be fair, and its driving conditions that counts for a lot,

anyway I have made a quick and easy MPG calculator for Excel, you put in price of fuel, how much you brought and what miles you did on that fuel and it tells you the mpg,

www.albioncranbourne.co.uk\MPG_Calculator.xls

the computer (I assume yours is a facelift) seems to be wildly inaccurate on average MPG and speed, my S class tells me I get about 8.6MPG on the way home where as my calcs tell me its more like 26..

Mine 230 clk Manual with Brabus K1 pack, now fully sorted, running about around averages 30 mpg, on a run anywhere between 34 - 36 mpg

 

[mbzclk]

hmmmm, what's the correct tyre pressure on the clk-230 with 17" amg wheels?

 

[Oli]

My old 230K used to do 30 MPG and sometimes over, 22MPG sounds more like 430 territory!!

 

[mbzclk]

will get it looked over, i certaintly thing its drinking too much, if i thought i would have got 20mpg i would have got a 200 non kompressor, but i was told 30mpg can be obtained, lets see what people think when they see it next sunday..

Another completely pointless MPG thread!!


The only way you can tell if you have a problem is borrow another car, same year, gearbox and engine and drive it for a week. Is it the same MPG? Then your fine.

Asking others what they get is pointless. I had this with a friend who also had a 535d sport touring, I got a constant 25.9 mpg, I could get it to 38mpg and get it as low as 16mpg, but if I didn't reset it for a while it would always end up at 25.9.

He insisted his car was better, he got 32mpg, always ended up back there.
He swore blind he drove it hard.

Then we had to both go to Wiltshire from Norfolk, I followed him on the way there and got 34mpg as did he.
On the way back he followed me, what took at 3h50mins on the way there took 3h10mins on the way home and he then conceeded that maybe he doesn't drive quite as hard as he thought he did!!

Oh, and both cars were showing 29.4mpg.



So asking someone else will just confuse you more.

The C230K engine as others have said, is not soo economical when pushed around town.

Mine is continually running around central London, so plenty of slow stop start driving and I get approx 22-25 mpg.

 

[Rose Chap]

I've done 60,000 miles in 4 years in my CLK, and never considered it very economical, getting around mid 20s mpg on average. Since my wife has started using it though MPG has increased to late 20s, and on a long run 30-32 mpg is on the cards.

If I was buying a CLK again now I'd get the 430.

Mine brings in a range of figures, depending on the route and how badly I want to get there

For the performance I dont think they're thirsty cars, and 30 should be feasible if you're willing to drive it gently. Fill it up as soon as the light comes on and re-set the trip meter, then see how many miles till the light shows again. That useful excel will tell you your true MPG than, as you'll have litres of fuel and mileage figures.

I for one am very glad that I dont have MPG displayed on my dashboard! Would make things far too sensible

Me too, the mpg computers are always very optimistic in my opinion, tank to tank is the only way

 

[Adam230K]

Based on my c230k, the c-class has 60 litres? which if you assumed 4.5 litres = 1 gallon so you get 60/4.5 = 13.3 gallons in a full tank. And on my car i constantly get between 290-320 miles on a full tank, bare in mind this is town only driving, and a heavy right foot. 300/13.3 = 22.5mpg which is crap! and hence why i want a V8!

But when i use W210 Fan's calculator it says 26ish mpg, which aint too bad...

The car's performance compared to its consumption is good though in my opinion... (performs like a 3 litre in my opinion)

 

[Roger Jones]

If these are the correct official figures:

EC Urban (mpg) - 19.6
EC Extra Urban (mpg) - 39.8
EC Combined (mpg) - 29.4

then I'd say there is something wrong with the car or your driving if you are nearer the urban figure than the combined figure, unless you are always doing short trips. The EC figures are never "real world", but something approaching the combined figure generally seems to be a realistic target. I get 27+ (long-term average) from my older, less efficient and heavier W124 E320 Coupé.

 

[Oli]

Sorry to go slightly off topic but does anyone know accuratly what the 320 and 430 MPG is like?.

 

[Rovinghawk]

13.3 gallons in a full tank. And on my car i constantly get between 290-320 miles on a full tank, bare in mind this is town only driving, and a heavy right foot. 300/13.3 = 22.5mpg which is crap!

These figures work if you run the tank to completely empty every time, which I doubt.

If you assume two gallons left when it's looking like you need to fill up then 320/11.3=28.3 mpg.

[bongolord]

My old CLK230 averaged out around 28mpg ish over 3 years / 100000 miles - low-mid 30's on a run.

 

[Roger Jones]

Looks like

Urban MPG (km/litre) 19 (6.73)
Extra MPG (km/litre) 37.7 (13.35)
Combined MPG (km/litre) 27.7 (9.81)

for the 320. Suggest you Google for the 430, which I guess will be 10% more thirsty.

I drive from Kent (15mins from Godstone M25) to West Quay Southampton and back every day (192 miles round trip) A25,M25,M3 and A34.
I fill up to the neck everyday and my consumption works out at 28mpg. My journey takes 85mins going and sometimes 110mins coming home at rush hour. (you do the maths for speed!).
I consider this to be extremely economical, for what is a fast comfortable cruiser.

One point to note though. I can squeeze almost a gallon more in the tank if I turn the pump handle upside down whilst filling. Not sure if this typical of all 202's and I know it doesn't make a difference to the calcs.
