all, i know was already discussed previously, but i'm enjoying my new old z 2.5i 2004 reg and i'm a kind of surprised that the onboard computer is telling me that i'm running at an average of 14 MPG (uk mpg) in city ride... Was not expecting 40mpg, but 14mpg looks poor... what do you think about it? I will check the MAF, what's your average in the traffic?
