@syed-shoaib, hashamraja, XaxoOBoY, rockerguy..............Bro's, thanks a lot for the kind comments, appreciate your appreciations, my pleasure.
@lovesleeping............... Bro, kindly mention specifics of your model. Moreover, if I really tried, I perhaps could push it even to 20kms/ltr, and had I been a bit more speed-devilish, reckless, I could even end up with 8-10kms/hour, so fuel-efficiency is a very variable factor indeed, ranging from sucked up filling stations to the weight of your very own foot on the pedal, and finally course, timely change of transmissions, controlling the cruise to be kind of smooth with minimal jerks, method of re-filling, etc. Kindly check these variables, whichever, and you'll find I'm right, the vehicle has a lot of potential for better mileage than you're getting, it's now more about improving upon the other factors as mentioned.
Regards.
