I have just bought a 2004 manual BMW 320 diesel ES Tourer. I switched on the computer at the start of a run largely in 6th gear of 130 motorway miles. At the end I had done no better than 45mpg according to the computer. I had expected nearer 60mpg for this journey as I was driving as economically as I could to test it out. Am I right to think it should do better than this? If so what should I do?

No. Remember it's winter and in lower temperatures diesels use more fuel. You might do better on BP Ultimate diesel (I do). But unless you drive at 60mph I doubt you'll better 45mpg by much.

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.
