Getting a 25mpg in my 2007 HB Yaris

What size are your tires? If they are overall larger or smaller than stock, this will affect your speedometer and odometer, and make your calculations inaccurate.

Also tell us about your driving style? Mostly stop-and-go city driving? What speed do you reach on highways, do you drive like Speed Racer all the time? There are a LOT of factors that can affect fuel economy!

i got a 17" rims. 205/45zr17 in the front and 215/45zr17 in the rear. Its bigger than the stock. i was basing around 2mpg less with the tires on. And its properly inflated at 33psi.

well, first of all. Im no speed demon so lets scratch the driving issue. Well, my place really is traffic, so its mostly a stop and go driving here.

On highways i go 35 to 50 miles

And mostly, i do this habit upon reaching the stoplight or when i know im about to stop, i tend to put the gear into neutral just to let the car glide. around 200m to 300m glide to the stoplight.

i shift at 2000rpm so i can say its the ideal shifting point.
