Thankx everyone for the replys, Ehsan_Zafar dose yours do 70+ with the Ac and if so then what seems to be my problem.
u no with an automatic CNG kit when the car starts on Petrol and turns to CNG by it self(so I have heard)(which is recomended for Mini) I do not have that, when I trun the ignition key the light on the CNG meter is on petrol for only 3 seconds regardless of me starting the car or not and then it turns to CNG after the 3 seaconds, in the automatic CNG kit, the kit converts to CNG only when the car is started.
I have filled me cylinder up to 5.8kg, yesterday I filled it up and it gave me milage of 45km with Ac and without Ac it gave me 55 KM.
I ahve read a topic on Pakwheels of a person saying that he gets 80-90km from his non-turbo Mini, so I was thinking of removing the turbo charger from my mini, I would like to know will there be any problems if I remove it or is there some other way to improve the milage.
also when I bought it I remember I did get 62km in one cylinder with Ac but the Ac was on level 1 and now a days I am using it on level 2, the Ac setting has always remained the highest.
The above text is from my previous topic, which did not get much attention.
