my eldest brother and i both have a jazz... i do normal city driving everyday occationally driving like a maniac and i get usually around 500 before the fuel light comes on, my brother drives highway everyday for about an hour there and an hour back he told me he got approx 650kms and when he filled up it had 5L still in it (we both use Vpower)... the figures honda tells us are true i guess its just a matter of how you drive it thats what i think anyway
