Today, my car gave me 14km/l round trip from nankana saheb to Lahore. Why it's so low?
While I was returning home there was extreme rain and wind all the way from nankana to Lahore.
In rain or wind every car will give a less fuel economy because your car have to do more work.
Also, this fuel consumption includes one run of 210km/h 
It's giving me 12-13km/l if I drive it economically within city. Those who say that their car only gives 8km/l are the ones who drive it on a hard paddle. 19/20 ka farq hai fuel consumption ka agar GLI say compare karo.
