C43 Mpg?

[noops]

New to the board, so please go easy. Sorry if I sound like a total idiot, but how you tell MPG on a C43, is there a readout, mine is a 98 S.

 

[jberks]

Do you have any buttons on the steering wheel? (did any W202s? - I suspect not)
If not you don't have a trip computer and you're down to working it out with a calculator.

 

[Blobcat]

With the calculator you have a much better chance of accuracy. The trip computers are somewhat optomistic shall we say

 

[Stulc]

Iv'e allway's used the trip, how do you know otherwise just how many mile's you clock up. Unless you take a reading from the speedo itself do so many mile's then fill up and it out on a calculator from that.

 

[Blobcat]

What I do is always fill to the top then write the miles on the receipt. As you will not always get a full tank (car learning, pump cutting out early) it is best to take the average over quite a few tankfuls. I built a calculator in Excel and have averaged 36.5mpg over 86K miles. Trip computer usually thinks I'm doing >40mpg

There isn't a readout I'm afraid you'll have to use the trip and your calculator.

If you drive anything like me it will tell you that you get around 22-24 mpg.

I (may have) got flashed by a Gatso the other day so I'm expecting my fuel economy to improve!

Stu, I meant trip computer, not trip meter.

 

[noops]

Thanks for the advice, good karma to you all, my only problem is that I only seem to get about 200 miles (town driving) from a full tank, is that the norm?, I know that I have a heavy right foot, but I thought I would get more than that.

 

[Blobcat]

Assuming 65 ltr tank (14.2 Gallons) and you fill up with around 10 lts (2 Gallons approx) left = 200 miles for 12 Gallons = 16.6mpg :!:
Not great

 

[jberks]

Sounds about right to me. It is a 4.3 V8 after all. I only got late teens / early 20's out of my 2.4 V6 pottering around town. It would have been around 200 miles to a tank.
Remember heavy, auto, 8 cylinders to keep running whilst idling in traffic It reckon thats actually pretty good!

Also sounds normal to me, it is winter, My 2.3 Volvo only returns 21 around town. 4.2 XJ6's only return 14.

Bugger, maybe I should have bought a diesel or drive bare footed, honestly I have no regrets about buying it, it's very much a Jekyll & Hyde vehicle calm and relaxed one moment and then without warning snarling and ferocious the next, even so it's mainly duel carriageways I always have a smile on my face when I get to work.

There is not person who has had a bad word to say about it e.g. family, friends and colleagues. I also found that other drivers attitudes to me when I drive is very friendly.

I managed to put some pics on, I hope you like her I certainly do, so go easy on her.

Just how many "big" car have you got..!

 

[jberks]

Beautiful motor. A true classic from the day it was built.
I still harbour an ambition to run something like that, but doing 25k a year its just not practical. Still one day ....

 

[converse120]

For town driving, I wouldn't be surprised at 200 miles per tank. I get about 260 normally out of my C43, but much of that is fast A-road. I've had as little as 220 when I've done more in town.

I also use the write mileage on receipt and calculate consumption in Excel method, and am averaging 23 -24 mpg over the 9 months I've had the car.

 

[Speedmaster]

I also have the 4.3 V8, albeit the clk430 cabriolet (so possibly not quite the same engine?) but i get exactly 200 miles out of a tank and that is pretty much all town driving and mainly short trips, commuting etc.

I have been on one longer trip and was getting 29mpg from edinburgh to carlisle (and not trying to be v economical )

It is thirsty but worth it for the wonderful v8 noise and awesome pull

 

[noops]

I got to go up to Lincoln next month, so I'm really to looking foward hammering it through the Hatfield tunnel with sunroof and all the windows open. :twisted:

 

[television]

it is only the difference say between 20mpg and 30mpg

Your big car does 20,over 10k miles the cast is 2250 liters =£2025
your smaller car 30 over 10k miles the cost is 1498 liters =£1348

So its cost you £677 to have the fun and the power, coupled with safety.

This argument was stronger years ago when a large car would out last a small one by double

Malcolm, my sentiments exactly. Please don't tell anyone as my tactic is to take advantage of the irrationality of people when selecting cars on fuel consumption grounds and so making them fantasic value second hand to me. Next car will either have a V8 (E55) or V6 kompressor (C32). The next but one will have a V8 too (C55 estate please....)

Thanks Angus, It becomes more stupid when someone like the man next door, who with an annual milage of 4k spent £7k down sizing to save on fuel.
