New to forums and first non newbie post.

I'm currently looking at getting one of these bad boys but have been reading mixed results on the 6.1L/100 combined fuel readings. I know the harder you drive it the more petrol your obviously going to consume but just wanted to ask what's everyones average tank lasting?
I am one to push the car from time to time but not a rev head like some. Also coming from a Honda Type R I've had the beauty of VTEC which requires some heavy throttling. I'm going to have to adjust to the 1-3000rpms rather then the 5-7000rpm.
