@lonic
bro most the time cng leakage is the problam...
in summmer i was getting around 140km with AC in city in around 360 rupees
now a days its 130km in 350 rupees...still i havent tunning for 2 months still i can improve it
these car will always give you less then 3rupees /KM
and on long route ....when i rebuil dmy car..with 2 person in my car through GT road to lahore.....it gave me 196km with 1 point remaining...i hope it would have touched 240 or something..which is unbelievable
@yr issue
if its leakage...only point will the nozzle of yr cylinder.... nothing else.....i have same when i was getting around 80 or 90km in full cyl....but on full day running 130km...
so i changed it ..which costed me 1700 rupees with engine tunning.....
@speed and rpm
i remember i never crossed 100km on this car with ac or with ac...the day i was getting good average ....as on high speed carb engine burns more fuel.....
and rpm should be decent like..not more then 3000rpm
traffic condition also effect...frequent changing of gear eeffects millage as welleffecteas well
