I average between 17-19mpg but that is mostly driving a daily 5 mile commute in which I average less then 10 mph. ---

well it is awd and altho not a “pig” its not honda light, i’d assume thats a pretty decent part of it… i’d say given the circumstances 20-26 isnt that bad?? ---

3300ish lbs + brick aerodynamics + small turbo (sees boost often) + stock tune that is way rich + cruise control can boost the car = MEH gas mileage. ---

Well, yea that is my reasoning. We were comparing the STi to a GTO. If you want reasoning on a case by case basis, everyone who gets better mileage than an STi can post up all about their ride, and we’ll break it down. Look, the bottom line is that nobody buys an STi for gas mileage, unless they are retarded. [Next page](https://forums.speedlife.net/t/sti-guys-what-has-been-your-best-mpg/51764.md?page=2)
