Decreasing Mpg

[Mark I Williams]

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!
