i average 20.0 mpg but on a good run can get 24.5 mpg - however on a trackday i was down at 8.3 mpg
It runs on premium so costs approx £80 to fill up
I fill it up every 4/5 days on average
when im busy i might fill it 3 times in 2 days
range is approx 240 miles for me
please ask Benjy to elaborate on him travelling at 50 -60 mph hehe!
I can get 25 mpg + over an average of an hour at 50 - 60 mph constant
