kafi khapny ky baad problem solved.... mechanic ziada hi taiz tha to us ny summer season ki wajah sy thermostat valve nikal dia tha, kehny mai choti si cheez but honda city idsi mai fuel average ka baira garaq karna ho to yah best option hy lolz
honda city idsi ki best fuel average depends upon driving habbit, usage of coolant, tyre pressure 32 (yah jo front tyres ka 28 pressure kehty hain woh ainween hi boss banay hoey hai) and long route par 2500-3000rpm ... easily getting 15+ in city area & 18+ on motorway
