Hi all,

Possibly a stupid question, I am not sure.
I have a 56 plate Cmax Ghia 2.0 TDCI and just had it serviced (37K on clock).
When stationery with or without your handbrake on and the engine ticking over, I have noticed the MPG dropping.
Is this normal?
As i always look at the MPG and not noticed it before.
I suppose it would make sense to drop as the engine is using diesel, but as I said I have never noticed it before and a friends does not do it.
