is the Air conditioning on? that will make a significant decrease in mpg.

[dannyboy88]

No change in driving style ? Have the glo-plugs been replaced ? My old Astra needed a new one when the mpg took a nose dive....

[dannyboy88]

nope still taking the same approach like i havent replaced the glow plugs i thought it should be a problem by now like

[lfcrule1972]

Normally the glo plugs last a long time but obviously they can develop faults, have you asked the dealer to take a look ?

It could be a number of many different things from tyres, to pressures, to road surface, to outside temperature, to load, to passengers, fuel be used, etc.

I wouldn't worry about it for the moment and just continue driving as normal, but keep an eye on it for the next few weeks.

i havent been to the dealer yet and i have had new tires but on there rating there were all in the C area as i got avon tires for the front

Glow plugs don't have any effect on fuel consumption. They are only active during cold starts. Aircon has only a minimal effect on consumption.

my 110 only averages 48.6 and has done since I got it last november.

Only time it increases is if I travel to london & back or birmingham & back on motorways - goes up to 52.6.

mind you, with cruise control set to 70 + (30 / 2) = I make that 73mph *cough* where possible I'm not complaining too much, although I wouldn't mine it being a bit higher around town.

S'pose it comes with the territory of driving it like you stole it all the time

[dannyboy88]

see most of my driving is motorway it hardly see the town like just thinking its werid that i was getting 66+ mpg now its decreasing i look after the car like anything it needs it gets to the best of the price like just werid that its dropping after this time

Cant believe the wifes new Fiesta 1000cc only averages 34 mpg! (All Town driving)
Even called the dealers and they said theyre not know for good mileage

My DSport petrol miles better

AND... can only get more in part ex for it than we paid 6 month ago

sorry i beg to differ, drove a DS4 HDi for two weeks and it was eating diesel by the bucket load. even performance dropped when it was on.
