My 2000 1.4 petrol 206 seems to have got very heavy on fuel compared to when I first bought it. Its recently been serviced and is well looked after. Only seem to be getting 28mpg on a run compared to 37mpg when I bought it 3 years ago. Car runs fine, can`t smell petrol. Anyone any ideas before having to go to main dealers?

I would check the plugs are good and a nice colour then air filter is clean then the maf mass airflow meter. In my old car I cleaned the maf with carb cleaner it was a wire type I sprayed the wire and the muck came off it so it measured the air/fuel better. Hence better mpgs. ? check exhaust manifold / downpipe for any cracks.

it could be anything. i´d use quality fuel additives, it will remove muck out of system.
in some cases, older cars react to some ethanol fuel blends with significant worse mileage .
exists also cat&lambda fuel additives, if these are dirty, mileage will go down
