When my aqua came it was giving a very good avg.i was using the car with a.c but temperatures were not very hot. And avg was like 28-30km per litre.... now a days avg has fallen tremendously to 14-16km per litre...i am sharing pictures of both times ...does anybody know about the problem with my car??? Is only operating the A.C is causing this avg drop or there is any other problem to look into.....anybody plz....
