when u get ur cylinder full,,,,how much kgs of gas does it fill,,,???,,,,,if it fill about 7.5kgs,then ur mileage is fine,,,,,my lancer does about +130km on a filling of 300rs(about 7.7kgs) in city.
waisay as a gud practise never get ur cylinder filled upto its max capacity because when the pressure in the cylider is high it tends to waste some gas,,,fill it upto 3/4 of its capacity and u will feel the difference.
bro wats this ''throttle body '' u r reffering too???
