The Jazz is 40 litres tank rite?
If it is then 8 litres travel 100km is totally possible, in fact it
is underestimating the FC of the Jazz. With its iDsi engine, my
friends are actually getting at least 16km per litre which comes to
6.25 litres for 100km. 8 litres for 100km is more for my VTEC City
which has more power than idsi but of cos FC not as good which
gives me average 520km for 36 litres which is 14.5km/litre.
