guys pay attention
talking about long routes
a 1.0 litre vehicle should do atleast 200+km in one cylinder (say 55L). in summer w/o AC 200km is rarely achieved because of the filling gas temperature, i.e., gas is less filled when its temperature is higher
in winter one cylinder fill should atleast do 200km. because gas is more filled and cold air intake.
I have khyber 95. i have done 230km in one cylinder on gt road (speed 70km to 100km per hour).
Inside islamabad it can go to 180km with daily cold starts.
The point is that cng has to tuned frequently. By tuning i mean gas setting.
whenever you clean the air filter, change it, gets dirty after sometime. even after filling gas you may need to change the setting. depending upon the gas quality.
