Hi all

I am the owner of a Ford Focus Zetec 1.6 Petrol (2009) in sea grey with 12,000 miles on the clock (pics to appear shortly!)

I have had the car for just over a week and whilst it is a joy to drive I am concerned about the MPG that the vehicle appears to be returning.

The official Ford figures are:

Urban - 32.5mpg
Extra Urban - 51.4mpg
Combined - 42.2mpg

For the first few days the car was being driven around town and returned about 25/26mpg on the computer. On Saturday I filled the car up and reset the trip and mpg computer. I then drove to Bristol and back, a round trip of 240 miles at a steady 75mph and on my return it read 38mpg.

I am in the middle of going a brim to brim calculation, however based on the computer alone I have driven a total of 240 miles and will drive another 170 before I need to refuel.

Therefore this suggests on a full tank of petrol (55 litres, 12.098303 gallons) the car will drive 410 miles. This equates to just under 34mpg.

Bearing in mind I am doing this calculation after a good 'run' and I suspect this will decrease as the remainder of the tank is likely to be around town.

I realise this is based on he computer which is just a guide, however gives a good indication that the mpg is not what it should be.

My driving style is quite defensive and therefore accelerate gently, anticipate traffic and cruise in gear when possible.

Does anyone else have this same issue?

Many thanks

James

Firstly, I would ignore the claimed MPG figures... there is no way you can replicate them in 'real world' driving. The best way to guage how economical you are being is by working it out for yourself (as you say, the car's trip computer is a good guide but not completely right. My last tank showed around 48 MPG, but when I worked it out myself it was 51). You will then over several tanks of fuel start to see what is average for you, I know mine fluctuate depending on where I've been and how quick I got there ;)

Secondly, 12,000 miles on a 2009 plate? Wow! Barely run in ^_^

Hiya James,

The MPG subject has been done to death [many times] instead of repeating it over and over and over, best if I just link to another thread which it self contains links to threads of a similar nature

[url="http://www.fordownersclub.com/forums/topic/14318-fuel-consumption-problem/page__hl__+miles%20+per%20+gallon%20+what%20+are%20+you%20+getting#entry91203"]http://www.fordownersclub.com/forums/topic/14318-fuel-consumption-problem/page__hl__+miles%20+per%20+gallon%20+what%20+are%20+you%20+getting#entry91203[/url]

Myself I'm a bit of a spreadsheet junkie, I just love collating data :rolleyes: Have collated three years worth of fuel data on my current Focus [most of my petrol station visits result in brimming the tank] This current years worth of data is due for conclusion 21st October 2012.

Currently the rolling average for this year [last brimmed 7th September] is 34.03 mpg

I've had dashboard comp readings of 19mpg around town, and once even a 57.30mpg reading on an 11 mile stretch A road cruising at circa 50 mpg. Trips from Yorkshire to Cornwall and back circa 900 mile doing 75mph on the motorways returned 36.32mpg.

Needless to say it's all down to driving conditions, driving style and speeds maintained. Forget the official figures they are not real world figures.

My tips are smooth and lite use of the accelerator , and attempt to drive in a manner that means you only touch the brake pedal when you want the car to come to a complete stop.

I second this. For example when I first bought my (diesel) Focus and brimmed the fuel tank, the trip computer said I had a range of 400 miles. Perhaps the previous owner was very heavy-footed.
Now it says I have a range of 550 miles, which is a very realistic figure for my driving - but it took about a month for the TC to recalibrate itself.

No idea how the TC calculates, perhaps it uses data from the last 10 tankfulls so that it has a realistic trend to base the calculations on?

As you can see, using an 'estimated range' to calculate your MPG is not accurate, especially if this is your first tank of fuel since buying the car.

But that's range, and you were asking about MPG

First, can you be certain that the trip computer is acurate? Only filling the tank every time and doing a manual calculation will give your true MPG. If you have a smartphone there are plenty of free apps to do this for you.

Secondly, the 'official' figures are done under laboratory conditions. This is to remove all other variables and give a consistent method from one car to the next, from one manufacturer to the next. Whatever assumptions have been built into these tests (traffic etc) may be completely unrealistic and could never be matched in the real world.

But they are the tests that Ford (and all car makers) must use, by law.

Maybe the test assumes that an 'urban' journey will spend 7% of the time waiting at traffic light, but in reality you spend 15% of your time waiting.
Maybe the test assumes that the outside temperature is 22 degrees but in reality it's 15 degrees.
Maybe the test assumes the roads are flat, but your route is very hilly.
Maybe the test assumes there are no other passengers on board, but you always have someone else in the car with you.
Maybe the test are done indoors on a rolling road, which is fatally flawed!
Whatever the reason, you will always struggle to meet the 'official' figures.

What I prefer to do is record my own fuel economy, and set a goal (currently 50mpg in my 1.8 diesel). If I achieve that I'm happy, but I have also done 60mpg - 20% better - on long motorway journeys.

Car makers must conduct their MPG calculations according to the rules laid down by the EU, to ensure consistency.

No car maker is 'lying', however it would be more correct to say that the official tests do not accurately imitate real world driving - but that is not the car makers fault.

Thanks for all your replies.

From doing a bit of reading it would suggest that the Focus is one of the poorer cars when matching it against the figures produced by the manufacturer.

As the car is only 12,000 miles I guess that the air filter or spark plugs couldn't be the culprit.

I'll keep a log of manual calculations for the next 1,000 miles and see how it works out.
Pitmonster
If you have a smartphone (Apple or Android) or even an iPod Touch, I strongly recommend downloading an app.

I use RoadTrip Lite (free) on my iPhone, and whenever I fill up I just put in the current mileage, price per litre, and either the number of litres put into the tank or the cost of the fill.

It can cope with a partial fill too, for when your skint and only put a tenner in.

It calculates the MPG of every tank, pence per mile, and does graphs for trends of MPG and fuel price. You can have your results in imperial or metric. Very good for a free app.

There are plenty of others available, for all platforms.

1.6L Ghia with 100ps here. I'm usually looking at between 34 and 38mpg. I sometimes see 40 if I fill my tank and do a long motorway journey right away, but most of the time with mixed driving it's between 34 and 38.

Pretty crappy tbh, but hey, that's life.

That is pretty low but seems typical from what I've seen on here. Looks like I'll have to live with it!

The roads you drive on and traffic conditions can have a massive influence on fuel economy. When we had the massive downpours last week and the roads were snarled up, I was watching the MPG reading on my trip computer go down and down as I sat in traffic.

Personal driving style is important too - in fact after we discussed the subject Mrs PM now matches my fuel economy when she uses the car, which is fantastic.
Scoobimax
Trip computer average for past 6 months is showing 46.4. When I used to reset the average for each tank during the first 2 months ownership it was approx 42.

That's in a 2.0 TDCi covering approx 15,000 miles over the 8 months since I bought it.

My driving style is rapid progress with plenty of forward anticipation - no Santa pod starts away from the lights but equally little braking/acceleration in the bends. Commute to work is mixed A roads, short motorway / dual carriage way stint and city centre driving - 27 miles each way so engine getting well warmed up for maximum efficiency.

Not done any manual calculations but may start using the iPhone app now though.

Hope that helps.

Interesting to read everyones experiences.

I agree that the official figures are in controlled conditions, however there is quite a difference between 25mpg and 32.5mpg.

I have read that an ECU re-map can give you increased power and torque delivery with increased fuel economy. Does anyone have any experience of this?

The gains you get from a non-turbo petrol remap are modest at best, and not really any cheaper to have done. So really there's no point - the economy savings are so small that it'll take you years to earn back the money you spent on getting it chipped.

Hi 100hp titanium 1.6 petrol, 2009, now on 13000 mls, i get between 31.8 and 32.8 mpg so the dash tells me, my own limited brain power says my car is doing 95miles from twenty quid, is this good??, its better than my old zafira.
Dont notice any difference between supermarket and shell/bp.
All our driving is 60/40 town and dual carrageway.

Depends on your local fuel price, but at £1.40/L and taking an average to 32mpg I'm calculating about bang on 100 miles for £20.

It's a bit close to the low end for the 1.6L Petrol. I'm on the 1.6L Petrol too, mixed motorway and town driving (most of my miles being driven like an old granny, might I add) and I'm getting between 35mpg and 38mpg - and tha'ts a 2006 model with close to 50k miles.
mobily
Apparently the increase in bhp is 10 and torque is about 12. A claim of between 5 and 10% increase in fuel economy. I am skeptical of this claim though!

Andyman - If you're getting 95 miles from 20 quid that's about 14.81 litres assuming you are paying £1.35 per litre. This gives you an approximate mpg of just over 29. It's quite low but seems typical for the petrol Focus.

[color=#0000ff][size=5][font=comic sans ms,cursive]If you are only getting around 30 mpg from a 1.6 petrol and I am getting around 37mpg from a 1.8 petrol estate with 16,000 miles on the clock, always 2 up on short 5 to 10 mile country road trips, then you do have cause for concern; are your journeys all start and stop, does the car need a service or is your right foot too heavy?[/font][/size][/color]
artscot79
i wouldnt say 30mpg was a cause for concern as said its all down to air temperature intake temps flat roads hills slopes stop start traffic wind speed head wind or tail wind etc etc so comparing mpg is a pointless exercise unless you live near the guy and travel the exact same route at the same time at the same speed at 60/40 town driving being the 60 then its what ide expect though ide look to eek some mpg back on the motorway however if its mainly uphill then its about average if its flat i would be a little unsure

at present i filled up with £35.00 of fuel at 139.9 per litre and in total have covered 228 miles and always have 50 miles left in the tank which makes 41.43mpg on a 10 mile journey with stop start for the first 3 miles then 65-70mph the remaining 7 miles some uphill some flat so i dont really get the car that warm it sits for 12 hours then i do the same route return on motorways i can get up to 47mpg it just depends
mobily
Around 30 mpg seems quite standard unfortunately for the 1.6 petrol for driving around town.

On a seperate note I e-mailed a local re-mapping company and received the following response. What they are saying seems interesting, but I do have some doubts!

[color=#262626][font='Comic Sans MS'][size=2]I would advise you that remapping on its own, will not improve your fuel efficiency on this vehicle, it will only improve your BHP by 9 and your torque by 15.[/size][/font][/color]
[color=#262626][font='Comic Sans MS'][size=2] [/size][/font][/color]
[color=#262626][font='Comic Sans MS'][size=2]Fuel efficiency can only be gained by having the remap in conjunction with one of our hydrogen-on-demand devices fitted. This way you will achieve the improved performance, reduced emissions and improved fuel efficiency of at least 20%. The customised mapping that we offer alongside the hydrogen system is designed to remove exhaust sensors which prevent the hydrogen from working at its optimum. [/size][/font][/color]
[color=#262626][font='Comic Sans MS'][size=2] [/size][/font][/color]
[color=#262626][font='Comic Sans MS'][size=2]The hydrogen product is covered by a 3-year warranty and a 30-day money back guarantee.

Iv have just moved from a 1.2 Fiesta to a 1lt Focus.
I never managed more than 32 round town in the Fiesta, max 45 on a long run in Wales. I was so disgusted with this I fitted a Garmin Ecodrive blue tooth device to my engine diagnostic plug. This gave all sorts of info to the sat nav device. It indicated all sorts of wild fuel consumptions and gave an average of 43, however on filling up and calculating the truth was 32 mpg.
My Focus now has a factory fitted consumption indicator which I hope is a bit more accurate. It at least shows me where the fuel is being used most.
I commute through Leeds twice a day, my 7 mile outward run is mainly down hill with light traffic. I purr along at 55 mpg dropping to 28 to rise up a few little hills or accelerate away from lights. Average mpg 44.
The home run Is through heavy congestion, I see the indicator at 5 to 9 mpg for a few meters at a time up a hill 1 mile long,I have two of these on the way home. Takes 30 mins to cover the return 7 miles. Average mpg 24.
This gives an overall of 34 (Ford quote 38 urban for this model). If I can find a flatter route home it will make a massive difference.
My conclusion is two cars cannot be compared unless they use the same route, stop start up any hills kills the mpg.
StanH
Have to say that I avoid short runs as much as possible (wouldn't think of driving to local shops 10mins walk away) plus I live in a flat part of the country with very few hills. I have no doubt I would do much worse in the Yorkshire Dales.

The 2006 Ghia does not have an instant fuel reading for some reason - is it possible to re-programme to get this?

Hi Stan,

You can programme the Focus to have instant fuel readings. You'll need a laptop, the free FF2 software which you can find here: [url="http://www.fordownersclub.com/forums/topic/31287-guide-for-focus-mk2mk25-c-maxkuga-elm-327-cable-and-ff2-program/"]http://www.fordownersclub.com/forums/topic/31287-guide-for-focus-mk2mk25-c-maxkuga-elm-327-cable-and-ff2-program/[/url]

I am paying 1.39.9 per litre and have to add that we do tend to be slightly heavy footed at times and yes most of our driving is around town.

Instant readout is a fantastic tool for improving fuel economy, as it really focuses the mind on how every single action affects fuel use.

Bit of a distraction though - you spend your time looking at the readout (trying to keep above your target figure) and not the road...

we have a 1.8 tdci 2008 titanium, before a re-map we were getting approx 37-39 round town driving, and top of 40's on a run.... after a map and full service round town averages 46-48, on a run last week coming back from hickley averaging 65, a steady 70 and a few quick bursts....., does drop down when using a heavy foot buy a couple of mpg, also sitting in traffic etc.....

1.6 Petrol Focus currently showing 36mpg on the trip computer. Driven 295 miles on a full tank with 104 miles left before I need to refuel. 200 of those was a good run at 75mph and the rest town driving and sat in traffic.

Based on this information I would be looking at about 33mpg.

Looking forward to refilling so I can do a manual calculation which I am hoping will be slighly more!

Update - I filled the car yesterday and then did a manual calculation:

Total miles - 317
MPG - 34.42

These 317 miles were made up of 200 on a good run at 75mph and the rest around town and a lot of it in heavy nose to nose traffic.

Geeks r us!!

Since having my scangaugeII fitted (Which in one of the sections I have instant mpg read out) Iv gained on average 6mpg! Its great to be able to adjust your driving style to get the figures you want.

Just done the nec and back motorway there A road back averaged 51 mpg with 56 mile range left that was on half a tank so that gives me a tank range of 600 plus on a run avarages around 37 round town this is on my 1.8 tdci

I’ve just got an average of 32.7mpg from my 1.6 100ps. Mostly stop start driving on A and B roads doing shortish journeys (no more than 10 miles at a time). Car is in need of a service too so hopefully the figures will improve after that.

So far driven 85 miles following fillup and this has all been around town very much stop start, short journeys. Trip computer reads 30mpg and going by number of miles left before refuelling I am looking at about an mpg of about 30.5 so it looks quite accurate. Official urban figure is 32.5 so the discrepancy is not that bad.

Looking to see how I can get the figures up when I do a run on A roads around 50/60mph

It's addictive!

I find myself trying to always beat my average, and it's also a great tool to check how accurate your trip computer is.

In 16.6k miles since I bought by car 11 months ago I've averaged 50.84 mpg, with a personal best of 55.18. For a car nearing 80k miles they're cracking results.

I love the way my mpg graph has gone steadily upwards (see the white line on this screenshot)

Even at today's fuel prices I'm running at 12.50 pence per mile which is a huge improvement of the 18-19 pence per mile of my previous car (1.8 petrol Laguna)


Does anybody use any other apps for mpg?

Well so far (1refill) I'm @ 13.7p per mile over my 417 miles.

Since my last refill I have done 140 miles, all town traffic, short journeys, never getting above 40mph and the trip is showing 28.7mpg. Not too bad for the type of journeys I have done. A diesel car would have conked out by now!!

i have a 1.6 tdci focus 2005 (DPF) had it about 8 months and no real issues with it, i do mainly town driving but also give it a good run every month.

i have worked out that around town i am getting 30mpg - surely i should be getting more than that??!!!??

i have it booked in for MOT and service and having air filter and fuel filter also replaced. its done 67k miles. will the service and filters mean i will start seeing better mpg?
Pitmonster
Maybe you will see better mpg after tge service, but town driving is always very heavy on MPG - if you look at the official figures it's always the worst of the 3 numbers.

Why is this?
Two main reasons:
1- plenty of sitting still at traffic lights and junctions, using fuel but going nowhere. In MPG maths terms your using lots of G for not very much M
2- plenty of accelerating away from rest. Accelerating is the very worst thing for fuel economy, and in stop-start driving you do a LOT of it. Of course it's not high speed stuff, but it's still the engine fighting to overcome the inertia of a stationary object, and that requires a lot of throttle use. You can't escape the laws of physics.

Any roads where you can cruise at a constant speed and on a light throttle will see your mpg soar.
