x type 2.2 diesel estate fuel consumption?

[CliveRothwell]

What MPG are members getting from their 2.2 litre diesel X types? (estate or saloon) I am looking for the average figure over a few weeks rather than a one run ie a proper combined figure over a tankful if possible please

The Jaguar website is quoting 45.6mpg

My concern is that my current 2.0 litre X type returns just 43.6 mpg agains jaguars claimed 50.2mpg and i don't really want to buy a car with a lower fuel mpg figure.
( the salesman says it will do 46 - 47 mpg but then he would!)

Thanks for a speedy reply if possible!
