#1: Totally Gobsmacked Author: continentalgt, Location: Paignton DevonPosted: Mon Dec 27, 2010 2:23 pm ---- Had the 206 1.4hdi since September and have always monitored the mpg very closely, I always go to the same filling station that has a flat forecourt and try to use the same pump. I always fill the tank until the pump cuts out then remove the nozzle for a few seconds for the fuel to settle then add fuel until it cuts out again. Next time I fill up I use the same procedure then work out the mpg with a calculator. Up to now on nothing but short urban journeys while driving normally I was getting around 42mpg, longer journeys on combined urban and A roads it's around 53mpg. Anyway we visited relatives over Christmas and as this was the first long run in the car thought I'd see just what I could get out of the old girl. I checked the tyre pressures which were about 3 psi down and topped them up and set off. Most of the journey was to be dual carriageway with a little bit of B roads and town work. I had the trip computer set to real time mpg and kept my speed to 55mph and kept my right foot as light as I could and believe me that aint easy. I covered 211 miles and my trip computer read an average of 61.4 mpg which was a little disappointing as I had already previously proven it to be optimistic. However I filled her up this morning and she took just under 13 litres, now that works out at 74mpg or 2.8 gallons.
I never for one moment thought it was possible to get anywhere near the official 78mpg claimed. To say I'm gobsmacked is an understatement, certainly wouldn't want to drive like it too often though.

#8: Re: Totally Gobsmacked Author: Andrew, Location: Black Country Ay IPosted: Mon Dec 27, 2010 2:35 pm ---- With a full tank you are carrying a lot of extra weight, if there was about a quarter of the tank in you would see the mpg go up, however that probably wouldnt be enough fuel to get over a long jounrey like you said. Official mpg readings are never the same as ours, as when the car manufacturers test them its probably with the lightest weight in the car, with early gear changes to avoiding burning more fuel in the high revs in lower gears, i wouldnt be surprised if they tested the mpg on a rolling road simulation type thing, they do everything they can to make the official figure as high as possible

yeah too true mate, they do do the testing on rolling road, and i only every put in £40 in the 206, about 3/4 of a tank, i might try it with 1/2 to see what happens
#10: Re: Totally Gobsmacked Author: continentalgt, Location: Paignton DevonPosted: Mon Dec 27, 2010 2:50 pm ---- Quite agree that carrying a full tank doesn't help but the only way to get an accurate figure is brim to brim fill ups.

Assuming Petrol at £1.20... That works out to 25 Litres @ 133 Miles.

Here in Torbay, Morrisons currently do it for £1.24 and I paid slightly less than that at the local Jet station last week. I wonder if they all hiked the price up for the holidays because the A30/303 is a major road out of the west country.
#36: Re: Totally Gobsmacked Author: Devon-Derv, Location: Paignton, DevonPosted: Wed Dec 29, 2010 6:40 am ---- We went around the gillingham/ shaftesbury area for christmas and saw fuel at £1.31 a litre for diesel. Morrisons in Totnes has been round £1.24/5 mark for a while now

You do know that on the receipt you get when you pay for fuel it says how much you have put in. Reset the trip once before you leave the forecourt and note the mileage when you fill up, you can do this for whatever amount of fuel you like.

Yes but it's only accurate if you fill it brim to brim in other words you start with a known full tank, reset the trip or make a note of the miles, do the journey then fill up to the brim again and note the amount of fuel added. Then you take note of the miles covered and do the calculations. Like the meerkat said Seemples

What if you get a couple extra squirts in (so to speak) when filling brim to brim? I can't see how that is more accurate than working it out from an exact mileage figure and exact fuel volume figure
I'm not saying how you are doing it is wrong, but to doubt the accuracy of the method I suggested seems a bit odd.

That amount you put back in is the amount you used?
Not unless you filled up to brim at the start and then again at the end of the trial otherwise you wouldn't know when to stop filling.
Also It's not accurate to use the fuel gauge as a guide as you couldn't hope to get better than within half a gallon or more which would screw the results. Don't forget I was after an accurate figure.
Anyone wanting to do an accurate check on mpg should try to do a distance of at least 150 miles, the higher the mileage done the greater the accuracy will be.

The first bit is obvious, of course you have to brim it twice.
How does doing more mileage give a more accurate MPG, all it actually does is give you an average.
I do fuel load calculations pretty often at work, my method is pretty accurate but this is because its taken over the same road over and over again in the same conditions. How accurate do you want to get, just fuel the bloody thing, work out a rough mpg and drive it, its not that critical.
#46: Re: Totally Gobsmacked Author: Edward, Location: In the garagePosted: Wed Dec 29, 2010 2:22 pm ---- I got 60mpg from a 1.4 HDi 206 without even trying. I think more than 78mpg could be achieved with a little care.

I have a question, how accurate is the low fuel warning light? Is it around 30 miles left in the tank when it comes on and how precise are the sensors that govern it?
You could fill to brim and note down the miles covered on seeing the light come on for the first time and continue to use that as a marker?

Ok so you put 20 litres in what does that tell you, only that you put 20 litres in it doesn't mean that you used 20 litres. It doesn't relate in any way to the mileage you covered.

monitoring mpg of your car is always good, it gives you an idea how health id you car. a suddenly drop mean there is something wrong!
I think one of the most interesting things I have discovered is that using your trip computer set to real time mpg actually trains you how to drive economically however absurd that might seem. We all think that we know how to drive economically but IMHO the trip computer really does make a big difference. Having said that I'd go nuts driving like it all the time.

Well I think I have a life, I've recently slashed my running costs by at least 50%, gone from a 26mpg petrol car to a diesel that averages over 50. Add to that much cheaper insurance and £30 a year road tax. No doubt you will be the first to complain when you pay an extra 16p a gallon next week and don't forget the price of fuel is going up again in April not to mention anything the robbing fuel companies wish to put on which will be compounded by the VAT.
No my friend it would appear that in your motoring world you are the true virgin.
