Just bought a 2006 Ford Focus Ghia Estate with Auto and Cruise control, 2
litre unleaded petrol engine. Mileage 27,900 miles.
Manual gives mpg as 42 mpg average of urban and non-urban.
I only average 32 mpg when just I am driving and no contents in the car.
This is even when I fill the tank with super unleaded. mpg is from the car
computer. I've verified it by a manual calculation also.
Tire pressures are correct. The car was serviced lat a Ford dealer here in
the UK ast week. The Ford Dealer said all the correct settings were
downloaded from the computer so all settings are correct..
Any ideas how to improve the mpg so it's more like what the manual says?
Or is the manual specification mpg all wrong in the first place.
