Suzuki Kei Fuel Consumption

[aahoo04]

Salaam all experts.
I've Suzuki Kei 2005 model with K6A engine. Its mileage was 10km/l. I visited different mechanics in Rawalpindi/ Islamabad and wasted money but could not increase mileage. At last I changed its engine but the mileage is almost same.
I asked different Kei owners personally and every one said that they are getting 18-19km/l inter city. If so, then what is wrong with my car? The engine is smooth, Pich is excellent, Everty thing is ok but no mileage. Can some one help me?
I think I need a good mechanic who may solve my problem.
If so can some one tell me what should I do and where should I go???
Thanks in advance.
