42mpg average at 70 in 5th for a distance. I average 40mpg if I am determined to save juice. but I wouldn't say it's granny driving as such, just changing at 3k with light throttle. always upto 70 at least.
the last couple of weeks however, my average mpg has dropped significantly, to more like 27-30mpg lol
getting used to it I think :d
