Hi everyone, I’ve had my 2012 Portfolio 2.2D for a few weeks now.  Now, I’m well aware that official figures, and, real world numbers rarely compare. But, I’m getting pretty poor returns so far. 
 
	I’ve just done a 500 mile trip, mainly motorway, not driving “enthusiastically”, and averaged 42.3 mpg.
 
	On the stop-start daily commute, I’m only getting 30 mpg.
 
	Is this the norm?
