i got 1.4 ex AT last dec, i've tried using different fuel from shell, caltex, petron, & stepping lightly on the gas pedal same result, i average 4.6km - 5.6km/L my current odo is 744, even if it's moderate to light traffic, very disappointed lang with my cars fc, but even though the car's high fuel consumption, i still love my car, still hoping in the near future CAC can come up with the remedy for it's rio's A/T high FC's, so if your really concern with FC, don't get a KIA RIO 1.4 AT, get another brand honda/toyota/chevy/mitsubishi,
