Thats pretty normal in my personal opinion. I geting 8-10 in city and 15 on motorway. It depends a lot on your driving style. My personal suggestion is to just drive calmly and stop worrying so much about fuel economy, if a car is giving 10kmpl and another is giving 11, then there is very little difference in terms of monthly cost. And take note its an old car, even new cars do not give exceptional mileage
