otromen02, i'm not sure on how unreliable that thing is, but i should say it is quite accurate for me... +/- 10km like that... on a full tank, the meter gave a reading of 450km until no fuel left... i went to about 400km then i went ot refuel to around RM65 like that... so it is around 16.25 cents per km or 8.46 litre per 100km (not sure if i do my conversion correctly). For urban driving, 16.25 cents per km i should say is quite alright.. average i should say... maybe slightly higher for manual cars... but i should say that during that time, i rev quite a lot as i am not familiar with the clutch... thus wasted quite a bit of fuel... but only rev below 3k rpm...
somemore, the car is relatively not conditioned.. thus initial FC might be slightly higher.. i hope that in future (after 1st service), the FC might dropa little to 15 or 14 cents per km...
from what proton claims, i think it might be true if we do not brake or anything... just continuous running at 90km/h... in reality, we can't do that...
