jdm models specially alto n mira dont come with rpms
issue arise with gear ... at 75km/H u r hardly touching 3k ..but at 95km its around 4.5k
as i travel often to peshawar...at 95km/H without AC it gave me 22.3 km /L with refuel tank ...
with 120km/H average i got 17km/L
with 110km/H with 2 pesengers it gave 15.5km/H
same test done with other cr alto 2008 5 speed manual i had ..even at 120km/H with 3 ppl on board it gave 19km/L
which was good enough
