11????? Never got anything more than 8.8mpg on a track!!!!!!
Only town driving is 13.smth now and on the motorway i never average more than 23mpg....
I would swear that after fitting the nismo exhaust and air intakes fuel consumption has got worse....it used to be over 14 around town....
But then again i love the sound so much that my ultra heavy right foot has got even heavier!!!!!
Oh well, as i always say, cars and women are for pleasure....so the more fun you have with them, the more you need to spend on them and vice versa!!! And good fun never comes cheap!!!!!
None of your MPG figures surprise me after reading about your brake and tyre usage!
