4AFE is a fuel thirsty engine it can never give you more then 9-10kmp/l in local and 11-12kmp/l on highway and that too for good maintained car, normally people get is 7-8kmp/l on this engine. In A series 7A is most economical engine i've heard it gives about 12-13 in local although it is 1.8L with some serious oil burning issues.
