sir, my car is a crosswind XUV AT, 2005. my concern really is its higher FC. some friends who owned the same car claims to have their FC around 10-12km/l (city drive) while mine is only within the 8-9km/l range. i had the injectors cleaned and balanced at a calibration shop near my place. however, nothing changed with my FC. by the way, it's a well-maintained car. anong pwede gawin dito para tumipid naman ng kahit kunti? thanks so much.
