I have it for 5 months now. Everytime I add gas I do the calculation and it always around 21.9 miles/gallon right from the first day I own it.
I drive it commute everyday and 1/3 of the route is on freeway. However it's around 20-40 miles on freeway during heavy traffic.
No matter what, it should at least has the city milage as Toyota claims, 24 miles/gallon, isn't it? Should I complain to dealer?
