What Mpg Are You Really Getting?

[ytareh]

My car is brand new and am getting 51/52mpg on mix of country roads and motorway (just over 80ish).Expected a bit better.Does it improve?Is it more sensitive than most cars to 70+mph?

I forgot to mention in my 'First 1000 mile ' report that 4th and especially 5th gear are SOOOOOO long.Was really expecting better economy....Despite giving the car the odd bit of welly I normally am quite light on the accelerator pedal ....

Your Aygo should get a better fuel consumption as the engine loosens up with more mileage ................however with a mix of country roads and over 80ish on the motorway you really cannot expect much more than the 51/52 mpg that you are getting.I am currently getting just over that on my 1.0 New Yaris

All small engines are sensitive to using more fuel when you drive uneconomically at 70 plus.

It is too late for you now ................but I firmly believe in keeping the speed and engine revs down for the first 1500 miles or so to allow the car to "bed in" gently.................Although not everyone shares this opinion.

I'm getting roughly 51mpg too.

I've had mine for 4 months now and have done 7500km (4660mi).

In summer I think I can get it down to about 58mpg;

you have to remember that winter is dark + cold + wet.

Dark+Cold+Wet=Heating+Lighting+Wipers=Higher Fuel Consumption.

Less speed on motorways will improve this figure. While the Aygo is a good car it's not an 80 mph+ cruiser. Slow to 65-70 - you'll get much better mpg and the extra time taken for the journey will be minimal.

My Aygo has 6k miles on it.

Most of it has been done on the motorway, although quite a bit of this has been a slow crawl. e.g. it can sometimes take me 2 hours to travel 60 miles. I rarely go above 70mph, what's the point? Some town driving as well.

Anyway, car does 57-59mpg no problem. Worst I have calculated for a tank was 54mpg.

[T.F.S.B.I.G.W.S.]

I do mostly urban driving and average mpg is about 44

I do mostly urban driving and average mpg is about 44

My Aygo has travelled 19500 miles in the 12 months I have had it and I have had an average fuel consumption of 57 mpg.

The car has been driven daily between Worcester and Birmingham, the journey consisting of 60% motorway, 20% dual carriageway and 20% urban. The urban traffic appears to have the most affect on consumption.

If I drive the car on a A/B rural road at about 50-60mph, I get a significant fuel consumption improvement equating to something like 65 to 70 mpg.

[DangerMouse]

Most of my driving is urban (stop/start), this results in mid 40's MPG. When i've had longer runs i have seen this go into the 50's. The norm for me is to fill up between 350 and 400 miles on the trip computer. Don't know what i'd have to do to hit 60's?????

By the way done 8500 miles

Ignoring, rightly or wrongly, the legality etc of travelling that bit faster Id have to say that I DO find it VERY hard to drive at 65-70mph on the motorway in a car thats well capable of doing so.The Aygo IS perfectly suited in my opinion to my daily drive and while yes, it is a bit buffetted by sidewinds Id much sooner try and swerve suddenly in it than my old Fiat Cinquecento Sporting at high speed.

The extra time does add up .Its easily 5-10 mins which is half an hour to an hour a week.Who wouldnt want an extra tea/coffee break every day......I am curious how much more mpg the more restrained driver might get so next tankful I'll try and keep it under 70mph.

Here in Ireland (Republic) the new MWay metric limit is 120kmh(75mph) and as far as I can tell most drivers dont go much over 80/81mph.However in England it seems that 85 is the 'unwritten 'average on the motorway for many.I guess that despite the persecution of motorists by speed cameras and horror stories about being caught a few mph/kmk over the limit etc that most feel 'safe' (from prosecution) at these speeds

Well all speedos over-read... at 70mph its normally about 3-4mph or so. So if you are doing an indicated 85, this would translate to an actual 81/82 or so, which realistically you are unlikely to be prosecuted for. Though you are far safer from prosecution if you stick to an indicated 80mph.

I too am disappointed with the economy of my Aygo which I bought entirely for low running costs. My motoring is almost entirely A/B roads and some motorway. I do not thrash it and generally cruise at about 65ish. best mpg I've acheived so far is 54 and worst is about 51.6. OK the car is still new only 5 weeks and has only done 3350 miles so has got a bit of loosening up to do but in my other cars I acheive at least 10% better than the quoted extra urban figure which for the Aygo is over 61mpg. I appreciate that the quoted figures are in artificial circumstances but why should my three other vehicles get 10% more than the quoted figure and the Aygo can't even acheive 90%! I bought the Aygo specifically to reduce my vehicle running costs, which it has, but no where near as much as I expected. It is a great little car though.

i don't understand how to work out the mpg but my aygo does roughly 100 miles to £10 same as my 1.2 clio used to do.

Its really easy Lucie.

Fill up the tank to the top... set odometer to zero then drive it till the fuel level is low. Then re-fill and note how many litres it takes and how many miles travelled.

Divide the miles travelled by the number of litres.

That will give you miles per litre. then multiply that figure by 4.54 and you will get mpg.

Eg (my 325i):

320 miles

47 litres

320/47= 6.8

6.8 x 4.54= 30.7

so average= 30.7mpg.

[lucie868]

thanks lauren i will try that next time!

is your mpg low?

[daveyjp]

Another way is to wait until the low fuel warning goes off. Put in a fixed amount - say 20 litres and see how far you get before the low fuel light goes off again. If you get 200 miles, that's 45 mpg.

[Jan van de Wouw]

Only problem with this method is that the warning

doesn't sound at the same level every time...

Because I'd like to know my average over a longer period of time

(multiple tanks) I even pay attention to refuelling at the same station

at the same pump every time, to rule out differences in calibration

between the pumps and between the auto-cutoffs;

I allways fill up untill it's shut of three times...

Ans yes, I even take note of the angle of the pistol

in the filler neck, as that influences the cutoff too...

Its not accurate though. Much better to do the tried and tested method as i described.

thanks lauren i will try that next time!

About 26, is probably about right for a 325i.

[yoyotame]

5.6 litres/100km

[SJandMR2]

5.6 litres/100km

ok slightly off topic here, but you know when the fuel warning light comes on how many miles do we roughly have left on that, cos I decided to petrol station roulette one day and lost very embarrasingly, now if it beeps I am straight off to the petrol station, didnt really matter to me much befor but now my commute only has one petrol station on route on hours drive and think this is a need to know problem??

SJ XX

[Jan van de Wouw]

According to the manual there should be about 5 liters left in the tankt when

the beep sounds / last bar starts to blink and 3 liters when the bar blinks faster.

But to my experience it's WAY less... I wouldn't even think

of trying to drive more than 20 miles with the bar blinking...

[matty_aygo]

iv got just over 30miles on the blinking light. was in the middle of nowhere just expecting the car to switch off any second luckly found a petrol station that was like £1.30 a liter as apose to 83p that it is where i live.

matty...

[daveyjp]

Waiting for the low fuel and adding a set amount is no less accurate. Modern fuel senders warn you at about the same time. My Audi 'bongs' when there are 8 litres left.

I know because I've filled it from this point plenty of times in two years of ownership and always get about the same amount in and if I put in 20 litres I expect to get 150 miles during my commute and this has been consistent.

We've only filled the Aygo once, but after it had 'bleeped' we drove about 20 miles and managed ot get 37 litres in it - so we were running on fumes. I'll check the '20 litre test' over time.

Filling to the brim, using it until empty and then refilling could be less accuate as you are adding more fuel. Fuel volume changes depending on the air temparature - the warmer it is the less fuel you get.

[Jan van de Wouw]

The problem with the warning is taht you'd have to stop INSTANTLY and refuel to be accurate.

And so far my warning has allways sounde JUST after passing a petrolstation on the highway :P

Annyway, I'm trying an "Efficiency Run" at this moment; trying to drive as economical

as possible for a tank's lenght, to see how low I can get consumption now :P

Currently I'm at 6.0 liters/100km and I hope to get it down to 5.5 per 100

First post.

Bought my Aygo Sport (C/Quartz, A/c) in Sept'06. Mightily pleased. (Traded in 8 year old Vectra Estate with 124000 on it. £170 a year Road Tax, so big change in size).

So along with everyone else, I absolutely love driving it around. I Grin from ear to ear, just like the grille does. It has the nickname of "I'll-Go" as that is what everyone says if a shopping trip in it is due.

Anyway, Fuel consumption. Low mileage covered since bought, so far only done 1200 miles. Just used for local runs, shopping etc, and the odd drive along the seafront now and again. 4th tank of fuel and all have so far given same return, 341 miles between fill and warning sound. Works out around 42 mpg, which I am quite happy with as it is double what the Veccie did.

I have tried on this tank not to use 5th gear as much, just seems to make the engine struggle too much.

Still trying to work my way through all the posts on here. Hope I don't experience the problems I have read so far, water leaks, engine management lights etc, Will add my comments as we go.
