Poor Fuel Economy - Help

[EviLNeeDs]

Hi guys, She used to run about an average of 80km/10 liters but recently its gone to 60km/10 liters.

Also my car is nearing 70K service soon, any chance its got to do with spark plugs or injectors?
many thanks.

80 kilometres per 10 litres works out at 22.6 miles per gallon.
60 kilometres per 10 litres works out at 16.95 miles per gallon.

Good thing fuel is cheap where you are!

I'm currently getting 33 mpg (around 116 kilometres per 10 litres) and my 200 needs a service. A good service might see some improvement, always with doing if it's due. A faulty exhaust sensor could also see a fall of in fuel economy. As could increased temperatures.

easy checks...

tyre pressures
brakes not binding

then engine checks - emissions but if that bad would/should put an engine warning light on

A service may see an improvement although my car was serviced 4k miles ago, i can't improve on 26.4 mpg
