Poor fuel economy

vulcanbomber

I drive a 1999 Ford Focus 1.8 petrol, it has 120K miles on the clock.

I have noticed racently that I seem to be putting an unusual ammount of fuel in the tank compared to a while back, I have calculated the ammount of miles to the gallon I am getting and to my horror it would seem that i am only getting around 23 Miles to the gallon.

I have the car regularly serviced and cannot explain why the excessive use of fuel should occur, ant thoughts would be most welcome

? Underinflated tyres. It knocked 10 mpg off my Peugeot 405.

Faulty lambda sensor. Mounted on the exhaust, before the catalyser.

best have it plugged in at the dealer that will say if theres any faults ...cant guess over the internet really

other than that...check the tyres are pumped up and no brakes are dragging etc

Thanks folks for the replies, I am going to get it checked at the weekend at my local garage who services it.

I did check the tyres and they were OK.

Change in driving pattern? More shorter journeys from cold?

All the other reasons given are also valid. If you find nothing untoward maybe time to punt it?
