LOL i think the SC owners will beg to differ. i've got an HSE and my numbers aren't going to totally accurate since i'm running 18s on fatty nittos, but my display says 14.5mpg for a commute that's 50-50 highway-street. for the past year, it was more of a highway commute and bumped up to 15. i'll get the SC owners chime in, but i coulda sworn it was in the 10-12mpg range.
