i noted a problem in my vitz driving on cng , that when i fill cng any where kpk and islamabad - sialkot my car has very good power in cng but when ever i go to lahore and fill cng , my car hardly moves like on cng it goes easily till 145km and when ever i have filled cng from lahore my car hardly crosses 90 speed , discussing the problem with owner of cng station he told me the gas pipelines till sialkot are from gujjar khan and in kpk gas pipe lines from karak and gas pipe lines in lahore and upper areas till karachi are sui , the main result he gave me was that sui gas is not very good quality as gujjar khan and karak gas is , so people who live in lahore - karachi i wouldnt suggest them to use cng in vitz , people living from sialkot - islamabad and then all kpk if they use vitz on cng thats good, recently i was driving on motorway in speed of 90 km / hr and mashallah i got an avg of 250km in 55cylinder i was amazed
