I have a 54 reg 2.0L TDCI Mondeo 130bhp. I bought it about a year ago and it has done about 96k miles.

Since I've had it, I've averaged about 56-57mpg. However, in recent weeks, this has dropped down to 53-54 mpg. I'm not aware of doing anything differently so can't work out why it's dropped so much.

Sometimes it does drop, but then it increases when I do my usual 28mile trip into work each day. This hasn't been happening of late - it's only been decreasing.

Any ideas?

Could be a few things,

Cold Weather, Winter Diesel, EGR Valve Blocked, Injectors Blocked.... to name a few..

Mine has dropped recently, i've just put it down to the cold weather and the different grade of diesel now winter is here!

At this time of year it is normal for fuel consuption to drop mine has also a 130 mondy
