I've just done about a 100 miles in the two weeks since I've brought my new Fiat 500 twin air. Should this get better as the car engine wares in. I'm only doing very short journeys, no runs at the moment.


Thanks.
 
Doing longer journeys and granny shifting will help it no end.

I get about 50MPG out of mine - some longer journeys thrown in there. You can reset the MPG if you want, then drive and get a fresh look at the number.
 
MPG figures are a fine guide to compare one car to another but do reflect an individual's driving style.

I drive 30 miles to work every day on 50mph roads so I always get in excess of 65mpg in my little Punto diesel. If I were driving 5 miles every day in bumper to bumper traffic taking the same amount of time then of course the MPG figures would be horrific, that's the nature of short journeys around town

Loads of people say that it take 5000 - 10 000 miles before your MPG will increase closer to the stated value that it should be. This is because the engine needs to be broken in

And as others have said it depends on how much stop / starting you do, how happy your right foot is on the accelerator and your gear shift.

Try coasting in neutral if you know the roads, follow close to the speed limit in rush hour, listen to the gear shift sign (i have one on my punto evo) and take excess weight out of the car.

Hope this helps!

I've done just over 12670 miles in my TA, and my journeys are 90% the 10 mile trip to work and back again (its about 18 miles a day) 5 days a week with the odd shorter/longer trip thrown in. I've never dropped below 40mpg, and only got above 50 once and that with drives to London or Eastbourne from Portsmouth.
On mine I'm at around 42-43 virtually the entire time.
(This in 95% ECO mode, I only switch on Sport mode after filling up for a few journeys or at weekends).

No no no, not only is this dangerous and far from recommended, it'll also use more fuel as you'll be keeping the engine at idle, in gear with foot off the gas on deceleration will cause fuel shut off to occur, increasing MPG.

Sorry for the ill-advice, i'm still learning :D

A simple google search agrees with you. Suppose you learn something new everyday. I just see my MPG go up when coasting in petrol and think i'm saving petrol.

So i should just take my foot of the pedal while going down hill but leave it in gear?

Indeed, this will result in the car shutting off the fuel and using none, the issue with the instant MPG read out is both doing this or being in neutral will show 99.9 as thats the max figure, but although in gear with no gas will use no fuel, in neutral the car will still be using some, and if the display had a big enough range it'd show it using fuel and returning a very high MPG in neutral where as foot off gas would show infinite if this makes sense?
 
All I would personally add is that I don't trust / rely on the cars indicated / claimed etc. MPG figures.

Call me a bit of a geek but for all the cars I've owned over the last 42+ years I have kept a fuel log book.

In this I record mileage, fuel added and most importantly if it was a tank full or tank not full refuel. I also record what average MPG the car said it had done. Very rarely do my and the cars figures match between full tank refills. Periodically I do a "To Date" actual average MPG calculation.

So for my Croma at my last "To Date" calculation I had done 64667 miles used 1909 gallons giving a lifetime average of 33.87 MPG (please note of these 64K miles some 30K were spent towing a caravan).

Once you get in the habit of keeping a log book (takes next to no time when you refuel) then it is actually quite informative and above all *accurate*.

For example. I've just randomly opened the log book and found a fuel full tank refill dated 24/06/11. Trip computer claimed 27.6mpg but the actual MPG was 26.2.

Also having a log book in the car you can record water top ups, oil top ups, other items etc. Do you *really* know how much or little your car has consumed over the last x miles?

All good fun :)

I think both statements helped me understand this. I have just joined Fuely which should help me kept a record of my true MPG off petrol receipts
 
I know nothing about Fuely which sounds like a fuel consumption program/web share site and this will probably be good for comparing make/model fuel consumption data.

However as you have to write a mileage on your fuel receipt then keeping a log book is, IMHO, just a little extra step to create and maintain a complete long term log from which all data can be put wherever, whenever you like.

Fuelly is in my signature.

No scribbling on receipts required, can all be done from a mobile :D
