Lol. 12 in city and 16~18 on long is a reasonable avg for Pak conditions (fuel/roads/engines/mechanic factors).
But every now and then, you'll see someone pop up with exaggerated figures of 17kpl in city and 25kpl long avg. And you would wonder if your car giving 12 in city poor and need tuning
One of my friends was boasting his Honda life 660cc gives 19Kpl in city and was very happy. I asked him about the figures of Km's traveled and litres consumed. And it came out to be 13kpl. He was so upset then.
Amazing how people boast about their avg.'s when they don't have even their basic maths right.
