Poor fuel economy in my Ford Fusion diesel 1.4 . What's the cause?

I have recently bought a Ford Fusion Diesel 1.4. It's one owner with 46,000 miles. I am only getting 43mpg on a combination of motorway and commuting journeys. How can I improve this?

By driving at lower revs. By changing the air filter. By switching to a better diesel such as Shell V-Power or BP Ultimate that might clean up the injectors and make the engine more efficient.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.

Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
