Dissapointed with 2.0cdti mpg

[Wrightski]

So I've had my astra sports toured a week and I'm pretty pleased with everything except the fuel economy im averaging about 42-44 mpg and thats in eco mode driving sensibly. My old car I traded in was a 09 vectra 1.9diesel and it averaged 49ish.
I thought with this being a newer car ( 2015 with 22k on.) I'd at least get something similar to the vectra.

So for those who've a standard 2.0 what you getting mpg wise.

I've had mine for about three years now, and general running around with the occasional longer runs I get about the same as you, 42-44 mpg. However on the Poland runs keeping it to about 110-120kph for the majority of the run I get about 54-56 mpg, but I tend to put better spec fuel in while in Europe as is a lot cheaper than here.
