7-8 wid light foot...damn :o
on light foot i got 10kmpl on my auto fuel guzzler
i cant keep light foot,not that light
cant change initial gears at less rpm like at 2k haha
on petrol pick is so good that it doesnt really feels much slow
i normally shift at less than 3k,i look at rpm meter only...after initial gears then i even shift at 2k
on cng i mostly shift at 3k,n if ahead of cars at signal,then tend to have little fun,but on petrol 3k shifts r enough for that 
there is something wrong wid ur car,manual shouldnt give that low average
which oil do u use,do u check tyre pressure regularly?changed air filter etc n when did u last got petrol turning i.e throttle body n tappets
