my automatic 2000 1.5 gets anywhere from 18-25 in the city based on the conditions
it has nothing to do with the tune, gas mileage hasn't been that great since i've had the car, I know the automatics don't do well on gas and the 1.5s aren't as good on gas as the 1.6s manual or automatic.
I can't explain why it gets such bad gas mileage besides that the automatic on mine sucks up a lot of power. The 1.5 is an old design that isn't all that efficient compared to the newer motor designs. Try anything you want to get better gas mileage it won't help that much i've been trying for the past 5 years.
also I forgot to add that my gas mileage suffers the most with a/c on during the summer and anytime during the winter
