Broh I just felt bad, very bad in that CNG wali thread. No body agreed and people felt as I am a sort of hate monger and rude, in spite of the fact that I tried to be as peaceful as possible. I kind of lost all taste for Pakwheels.
This should get better with time. I don't know whats happening, but my car's average seems to get better all by itself. When I bought it, its average was 18-19 kpl. It just keeps getting better (like I wrote in the above response).
A couple of months ago I decided to make a world record and drove as slow as possible. I drove between 70 and 90. That day I very difficultly got 20 Kpl.
Yesterday I was like, forget the average man just drive normally. I kept the speed between 90 - 110. Average being 100 km/h. I didn't even have the AVG tab in front of me, rather the Trip tab was in front of me. I just switched to see what average it was giving and I was amazed! 22.8! I was shocked actually. I had only put 1000 rupees of petrol from Pindi and here I have made a trip to nowshera once again (Rwp - Peshawar - Nowshera - Back to Peshawar) and I haven't refilled the car yet.
The reason why you aren't getting these averages could be because you're car will start showing optimal fuel efficiency after 10,000. May be 12,000. This is what happened with me.
