Recent MPG

[pioneercollector]

From my standpoint the original posters MPG is very good, The best i have managed in mine ( Completely different model ) is around 28 MPG, which i was very pleased with. I find that the bigger engined cars tend to be not too bad as you need to press the go pedal less to get moving ..... but obviously there are times when you do otherwise we would be lusting after Honda Jazz type cars

My 1994 s124 E300D (diesel EUR 0!) 4 speed auto 200k+ miles would do 45mpg driven at 55 mph on long continental trips. One trip to Brecon from London achieved this mpg with 5 people and baggage in the car.
I should add that the 2016 s205 C200SE (petrol EUR 6) 7 speed auto 180k+ miles has done 60mpg+ on long UK motorway trips.
Your mpg seems rather low.

Hi , well my C207E400 ( with the 3.5 petrol engine) has achieved the following fuel consumption.

The car has over the last 7 weeks has traveled 693 miles and averaged 28 mpg : stop start miles : hilly area and yesterday's journey.

Yesterday I drove 245 miles and averaged 38 mpg. ( Included in the above miles )

I used the trip computer on this occasion to calculate mpg but when I fill up brim to brim similar results.

I prefer to use 99 octaine petrol but the one station where I live that use to sell 99 octaine now sells 97 octaine fuel.

When possible I prefer Shell V Power

CLK200K last week happy enough as half the mileage on that trip was city driving, traffic jams, roadworks & the other half silly speeds to make up time.
Overall on that tankful I got 24mpg. Esso Super unleaded.

My 2011 E250 CDi Coupe regularly reports 60 - 65 MPG on a decent run. Which I find incredible.

That's about what I used to average on mine....around 30 to 32 give or take.....never seemed to vary much either.....long journey or short. Just standard fuel used in mine though....they don't need over 95 octane like some Mercedes do. You must have a heavier foot than me (no problem with that of course!!).....never got as low as 24 mpg in the time I owned it.

Just drove the 1991 300-24 from the Dordogne to Poole. Just over 800 Km. 30 mpg almost exactly.

I used to see that on my 300-E 24 though urban driving saw it use 15 to 18!

On a similar vein: how many of you trust your onboard MPG read out? Only brim to brim is reliable but many don't check because they'll be very disappointed

So, 2003 CLK500: 30 mpg at 70 mph with no holdups (which I think is amazing). 25 mpg at a more realistic speed (i.e. 80-90 m/way + a little town driving). 20 mpg in town as long as the traffic is moving. 16 mpg in town if a lot of stop start. 12 mpg if the traffic was full on London-mode.

Have not checked the CLS55 yet - I'm hoping only 2 or 3 mpg less but the dash is saying worse

Plug in hybrids are not much better. The Volvo XC90 t8 hybrid claims 44 miles of range on its 19 KWH battery. Current electricity is about 30 pence per KWH (more outside of home). So that is 570 pence to charge up and you will get about half the advertised range, say 22 miles. 570 p / 22 m = 26 pence per mile cost.

My 5L v8 merc did 23 mpg in combined driving. A gallon is 660 pence. 660 p / 23 miles = 29 pence per mile cost.

The whole raison d'etre for hybrids is you have a 2.5 ton SUV running on electricity around town, and on petrol on the motorway. I think a more sensible aim would be walk cycle and bus around town, and v8 on the motorway

If you are a politician & stand on promise of V8 for everyone subject to drivers using shanks pony & cycles locally, you have my vote

Haha. Yes, I used to get about 33 from Dordogne to Paris. Then misery around Paris. Stop start, 15 Kph.

Happily, I'm teleworking now from the Dordogne where Iim getting 27 mpg on 20 Km trips to supermarket and children.

And I've had to rethink how I assess motoring costs. Is 130 quid in petrol OK for Dordogne to Poole - 500 miles, 2 people and loads of luggage. Yes, much cheaper in the Yaris but bloody noisy and not much room.

Did a 1000 mile round trip to France the other month.
Worked out as 38 mpg on my E350 cdi
Was quite pleased as included motorway and pootling around.

Alway think if your happy with then that’s great. It’s better than my old Discovery Td5

 

[Phil1968]

Journey from Devon to Kent a couple of weeks back, mostly motorway with a bit of city driving at either end. Not bad for a 5 litre V8 I thought & I wasn't driving like a granny either.

What model is it? My CLK500 was similarly frugal. When you consider how much extra diesel is (usually) it does make you wonder why people bother (unless they're doing 20 plus thousand miles per year)

Never understand the "on a run" thing.
The only relevant mpg is over the course of a year.

Merc V8 vs BMW 320i: it's 27mpg vs 44mpg.
Call it a grand if you're doing 8,000 miles a year. (plus RFL difference)

Roughly the cost of you both going to Glastonbury this weekend.
(Not that you can buy Glastonbury tickets because they sold out within an hour last November)

In the grand plan of pleasure and cost of ownership and depreciation, tis not a big difference.

Just popped to France in my new to me 65 plate 80k C250d Estate, 9 hours mostly motorway at 65 - 75 loaded to the roof, got 57.4 mpg, incredible, half a tank left. The old sl would be on its second tank now. Still keeping it though

In my personal experience in mixed driving I got ~36 mpg in a C270 CDI (2006), ~42 mpg in a V70 D5 (2005), ~44 mpg in a 320d (2007), ~43 mpg Golf mk5 2.0 TDI, and for comparison ~38 mpg in an Alfa Gulietta 1.4 petrol turbo (2010, lovely car) and 31 mpg in a C200 petrol (1999), BMW 318i ~35 mpg (2003).
For me a 320i would probably be doing 30-35 mpg vs 23 in a 5L v8. Approx. £700 difference per year, assuming diesel is the same price, which it is currently. Not insignificant, but worth it.
(Curiously my 318i 2003 does about 32 mpg on high speed motorway runs and the v8 does about 25. But obviously the 318 is far better around town and shorter slower runs).
I still think high speed: v8. Low speed: legs
