C250 Class Coupe 2012

[batters]

Hi folks

My car seems to be doing a lot less MPG than it was a week ago.

I normal get 570-600 miles to a tank, and just got 500....anyone have any ideas?

Sorry if there is an obvious answer

Assuming your car is a diesel, It could maybe be due to weather getting colder.or changes in driving style/ pattern. Try putting some injector cleaner into your fuel tank or alternatively use BP or Shell premium fuel...BP Ultimate or Shell V Power respectively.

I'm not sure whether or not a clogged DPF can cause higher fuel consumption... Maybe worth taking the car for a 20-25 minute run to clear the engine and DPF out, if the car is used in stop/start city driving most of the time.

If no difference then it may well be something more technical...but I had noticed that the fuel consumption values varied alot.in my dad's 280 CDI.

Try some redex

And quality fuel

Redex (or Forte, or Millers), OR premium fuel, I would say...

Hi, check your tyre pressures.
