I am running a 1.6 TDCI which is 10 mnths old, and I can`t get better than 42-43 mpg,is this normal ?

I GOT A 1.6 PETROL 13 MONTHS OLD AND THE BEST IT DOES ON A LONG TRIP IS 38 TOTHE GALLON THATS 10 LESS THAN MY LAST CAR A 1.6 SCENIC

i average 45-50mpg from a 2.0 130 but it depends on driving style this can drop if driven hard (carn't resist some times)

I get around the same while driving around town. My trip to work is a 17 mile trip along an A-road and I get around 55-65mpg if I drive very carefully otherwise this'll drop to around 45-50mpg if I do overtake anything and keep up with the traffic!

I was expecting better to be honest.

Chipped 1.6 tdci

was returning around 42.5 mpg around the village odd trip into town.

with chip on there is def more power so the temp to put your foot down is crazy but honestly if you keep off the power pedal

then it does 46 mpg does not sound much but its 3.5 miles and if you want to you can cover them quicker.

Views on chips please?

Hi only just noticed your post. I've been looking at Bluefin chipping system (£381 all in) by superchips for my 2.0TDCi. I've attached the dyno data (pdf file) for my car from superchips. It looks like the 2.0TDCi they tested put out 152bhp standard at the flywheel (Ford quote 136bhp - is this at the wheels?) With the chip fitted it gives 176bhp at the flywheel so i presume by the same factoring this is @157bhp at the wheels. What make of chip is yours? Also just had an insurance quote off www.adrianflux.com (modified car insurance specialist) that is only £40 more than i'm paying now with the chip fitted, lowered suspension, sport dampers and 18" wheels!!! There's not much pursuading me not to go for it (apart from the missus!)

Been investigating poor mpg in the c-max for a few weeks now.

A lot of people seem to be having the same problems. I average ( in a 1.6 tdci 57 plate) around 43mpg going to work and back (20 mile on a-roads), with the maximum of 50mpg on a motorway at 60 mph . Frankly, I am very dissappoined, especially when comparing with the quoted combined average of 57 mpg from ford, and comparing against my previous diesels :-

Rav4 2.0 ltr average 39mpg (4 wheel drive and heavy) , motorway 47mpg

Toyota auris sr180 2.2 diesel average 47mpg motorway 56mpg

Skoda vrs diesel 170 bhp estate average 47mpg , motorway 58mpg

civic 2.2 diesel, average 52mpg, motorway 60+ mpg

You can see from these figures, that my previous diesels have been much bigger and faster cars, yet have returned much better economy.

I have checked :-

1. the ECU fault codes, none exist. got a lead from ebay.

2. any leaking air inlet pipes, especially the large one across the front of the engine, all air tight. quick check is to open the air filter box and block the air inlet pipe at the MAF sensorto see if you can stall the car and watch all the pipes collapse under suction.

3. cleaned the MAF sensor.

I am now going to see the ford dealer to see if there is an ECU update.

I would also be interested in anyone else with the same engine and an OBD lead to see what air flow, air temp, oxygen sensor, rpm and fuel pressure they have at IDLE, 2000 and 4000 rpm for comparison.

any other ideas would also be welcome.

Surely a 1.6 turbo diesel should be much better than 45 mpg.

I am tempted to buy a diesel chip for better economy, but want to see if there is a faulty sensor or ecu first........

hi i am new to the forum and i am finding it very interesting and good for advice. i have a ford focus cmax 1.6 tdci auto ghia 2005 and we can only get 30mpg according to the trip computer on short journeys and 52mpg on the motorway, we are going away soon and its almost a 400 mile journey we fill up at tesco at the moment and wonder if we went to another petrol station like bp the mpg would improve, the car is regularly serviced at our local ford dealer if anybody got any ideas as to what else we can do to improve the performance of our car it would be very much appreciated thank you

Hi all,

The fuel you use also makes a difference to economy as supermarket fuel is not very good so try to use shell etc as it's a much better fuel..

A good remap on any car will give power/torque and improved fuel economy..

manufacturers figures are very rarely met in the real world of driving on the road.

If anyone requires any info etc on remapping please just ask or have a look on my website... :)

Did you ever got the ecu updated? did it make any differance to the MPG?

Hiya...for what its worth..my c-max was showing between 32-35mpg...what i did was to disconnect the battery for 15 mins..(if you see my other post on ford c-max i thought it may do something!!)....after all when your home pc freezes you disconnect it from the mains and "hey presto" it works fine again..anyway i disconnected the battery and next time i drove the mpg rose dramatically....it now does at least 51.5 and the highest ive had is 59.6....this is "normal" driving not long motorway driving,as regards to the other issues with the car..there is no improvement....but give it a go...it wont cost anything...but make sure you have the audio codes!!...hope this helps...Rob

Hi as posted above, disconnecting your battery makes the ECU relearn it's values so you should normally see a difference, also worth doing if you change to shell v power etc..:)

Having just acquired a C-max 1.6 tdci 57 plate we've also found that economy seems very poor. We've just averaged 41.5 over our first tankful. Tried disconnecting/reconnecting the battery but, sadly, no difference of note. :(

The car still has just over a year's warranty so I'm tempted to take it in to a dealer to see what they can do.

If anyone has any suggestions, I'd love to hear them (other than "shouldn't have bought one of those!") :blink:

cheers

the MPG on our 54 plate 1.6 TDCi went up from 45 to around 50 when I changed the front brake pads which were very low. I wondered if it was related to the amount the front caliper pistons were extended

Hi,

I've got a '55 plate 1.6 petrol, and its terrible for consumption.

My wife drives it mostly (she does have a heavy right foot) and does a lot of local runs.

She averages 29 - 32 MPG.

I had to disconnect my battery overnight last night, and I've just noticed I got 36 MPG on the way to work this morning !!

WTF ?!

Certain of the petrol engined variants don't give good economy due to the way the geartrain is set (try looking at what engine speed you are doing at motorway driving speed)

the diesels are doing less than 3000 RPM at 80 MPH even in only 5th gear

Hi there I have an 04 Cmax 1.6TDCI. I was impressed with the performance for a small diesel and expected high mpg rates. I was a bit disappointed. This is what I get:

round town just local trips: 41mpg

mixture of local and longer runs: 50mpg

Long trip: 55mpg

Long trip driving like a saint 60mpg.

I once drove to Redditch to see my son. I am in North wales so filled up in Bangor - drove 155 miles - I knew he didng finish work til 5.30 so I wasnt in a hurry to getb there so I drove at 55-65 and tried to anticipate road conditions best I could and really nursed it along. The result? filled up and was shocked to need only 10.75 litres. This worked out at nearly 71mpg. Dont forget this is checking the maths on amount of fuel needed over a given distance not the computer in the car.

I was delighted with this but rarely have the patience to drive like that. Typically get 55 on a good run and thats cruising at 70.

As the fuel economy is such an issue, I would suggest anyone taking a cmax for a test drive should check what the average mpg indicates on the display from the previous owner, unless of course some one has already reset this.

This will give you a clue on how it has performed over time, alternatively, if it has already been reset by someone, reset it yourself during your test drive once you have determined this.

You would know if it has been recently reset because,

1/ the average mpg will be on zero in the showroom or..

2/ while viewing the average display and while driving gently, it will quickly change to reflect your economical driving habit and will improve very quickly. If the display doesn't change quickly it is likely that the average reading hasn't been reset recently and will be a better indication of it's average mpg over time.

This is all to do with it's sampling rates.

If you reset the display it samples fuel flow against distance and samples,say every 1/2 mile, so because you have not done many miles as a comparison it changes quickly. Now once you have done a hundred miles or so it has a wider sample rate to judge itself over so the display changes much slower.

So if you reset your gauge and say drive 20 miles around town, your average will be based on stop starting driving, while on the other hand if reset prior to a motorway run it will be based on a continual run.

In reality (if you don't reset at all) the computer averages both town and continual and gives you an overall average.

Long winded though it sounds.......it is worth a try as it could provide evidence of the better mpg averages when comparing like for like vehicles.

When you read on this forum how some people report getting 35 mpg while others say they get 60 mpg.......the evidence may be right in front of you while test driving.

Give it a try

Titanium is my latest CMax TDCi - Infact this is my 3rd CMax.

Others all 1.6 worst 39mpg - best 52mpg.

Not sure what should get from my 2.0 Diesel.

Just coming upto 10K.

The main thing - Just enjoy.

We have a 1.6 petrol zetec and best I can get is around 36 on a motorway drive, not very impressive given that I've been using it regularly on my own (no wife kids and boot full of usual rubbish)!

Think this needs to be explored a bit more as I was expecting a little bit better on a careful motorway drive....

I'd really like a group of us to try an experiment.

If you look on the ford website it gives details of how they conducted their mpg tests.

My figures are not even in the ball park.

I'm a carefull driver, light on the throttle yet I can't come close to fords mpg's for my 1.8tdci.

Even given manufacturers tolerences we should be closer than what we are.

I would love to hand my car over to an organisation ( top gear or fifth gear tv shows ) who could mimic fords mpg tests and have a real comparison, because there is something wrong somewhere and to be honest it is not just fords.

When you consider we base our purchase on a manufacturers figures, to then not even be close is out of order.

Another idea would be to get a fairly flat motorway run of a couple of miles, select cruise, select speed to take away the drivers hoof out of the equation, reset the menu mpg and record what the car does and post it here.

Imagine if we could grow a database of similar runs from similar models it would provide a wealth of info for owners and buyers alike.

We just need someone to facilitate the experiment.
