Still in the break in period as well... got about 1700kms on my car and have filled it up 4 times so far. For each full tank I've averaged anywhere from 16.5L/100kms (all city, driving hard) to 13.2L/100kms (mostly highway, driving hard). On long highway trips I've averaged under 12L/100kms so pleasantly surprised... but man does the fuel economy ever take a hit when driving hard in the city.
