Hi sirs;

I am just new here, i recently bought a new 2013 A/T Toyota Vios E. i was informed that it has a fuel consumption of average city driving 13km/liter. pero nung ginamit ko sha, lumalabas na 8.4 kl/liter lang sha. yung 500 peso ko na gas tumotal lang ng 81 kl before the fuel sign started lighting up. is this normal? nakaka 800 kl palang sha since makuha ko. thanks in advance.
