I get 18.5-19.5MPG on average, doesn't do much better on the highway because I have a roof rack.

I get around 27 mpg in my '10 WRX w/ Cobb Stage 2 tune + DP and I go WOT every time I drive it.

RPMs over ~2500 make your gas mileage worse. I'll accelerate up to 3-4k in normal driving, then shift to bring revs <2.5k. I often cruise down hills in neutral.

I get 24-25mpg driving 80-85 on the highway.

No point to be had. Just never knew what you drove. Figured it wasn't a Subaru since most members who have been on here a while don't drive Subaru's anymore.

I bought my '07 WRX new 08may07

I get about 22-23mpg on the highway and about 19-20mpg city in my STI. Even with the center diff out of auto and unlocked the most with the SI-Drive on "i" mode i still only get about 22-23 on the highway.

I have a turboback, intake, turbo inlet, and tune.

Never measured, but not unbelievable at all. Water is immensely denser than air. When you're driving at speed, your car is bulldozing not just through the atmosphere, but all the water falling onto it as well. Add to that the extra drag from water on the skin, the extra weight, and the additional power required to push the wheels through puddles and wet ground, and a 10% drop in efficiency really isn't out of the realm of likelihood.

Yeah, it's surprising how much drag is applied to anything moving through rain (as opposed to no rain). I had a friend who was a sniper in the military tell me how much they had to change their trajectory calculations if it was raining out... I don't remember exactly (maybe someone here can confirm/correct me) but it was something crazy like an extra foot of drop per couple hundred yards. I had no idea either.

Maybe you need to replace your spark plugs. I get only 150 miles to the tank(about 12mpg), and some of those are highway miles and I haven't replaced my spark plugs in 40k miless. I'm getting them replaces tomorrow though. So ill let you know of my mpg increase I get.
