Mazda 6 Tourer - Why is the fuel economy so poor?

I'm disappointed with the fuel consumption of my Mazda 6 Tourer 2.2 diesel. I never see better than about 44mpg on motorway runs (400 miles in a weekend), and only return 37mpg on town driving (which I could excuse).

The motorway figure is so far out from the manufacturer's figure that I've had it back to the dealer three times, and they can not find anything wrong with it. Any tips on how to get satisfaction?

Well, I averaged 49mpg over 14,000 miles in a Mazda 6 2.2d 150 SEL-Nav auto: www.honestjohn.co.uk/our-cars/mazda-6-22d-se-l-nav.../ The Real MPG figures are here: www.honestjohn.co.uk/realmpg/mazda/6-2013/ You will do better on superfuel such as Shell V-Power Nitro + or BP Ultimate.
