About 300 miles on my '13 WRX now and just barely above 20mpg. As most of you I'm sure, I did not get this car for the mileage but wouldn't mind getting a little bit more.
Coming from a 6-speed Toyota Matrix with the 2zz under the hood (rev-limiter near 8300rpm, lift engaged at 6700) I'm new to this 'low rpm' motor. Still in the break in period, I am not shifting above 4k but find it hard; can't really even go WOT in 1st, barely in 2nd, and 3rd I can WOT a bit. I read some of you, to maximize fuel mileage, are shifting as low as 2k--mind-blowing! Maybe I'm just not used to having the TQ and HP of this vehicle so it's hard to wrap my head around shifting that low. Even at WOT though, 2k won't really have any turbo spool, where's the fun in that?!
