well I own a 08 swift sports manual , 1.6L my case scenario a decent drive gives me 10-11 km/l in Colombo in rush hour & I’ve got a reading of 16km/l when I drove to dambulla (soft on the peddle) , if I drive aggressively like hitting 7000rpms to change gears , then consumption per liter drops down to 6-8 km/l. I think 1.3L should give more km/l , the jeep model old swift which we have does 12-13km/l in Colombo.
