I thought it required 91, and you could use 89 if you got the 2.5 RS. The turbo I thought required the better fuel.

My Manual says Premium 91 octane or higher fuel only.
It also goes on to say that for short periods one can if no premium is available use lesser grade fuel.
Regarding mileage:
I have a long commute (reason I bought this "fun" car and average so far around 22-23 mpg

How many miles you have so far?
I only have 1500. I think she is still breaking in and getting into stride.

I test drove a WRX wagon with manual tranny today. It pulls pretty good once it's into boost. Real doggy in the higher gears though. But I never got to any highways speeds.
What's the difference in performance between the auto and the manual?
I wouldn't mind having it at all. Although it doesn't look like my wife is going to go for it.

It pulls MUCH harder once you drop in an MBC for <$50. Test driving a stock rex is impressive, but a go for a ride in a BPUed (basic perfromance upgraded) version and it'll blow your mind!
I can't wait to see my fuel economy once I get my uppipe, and downpipe in. If I can stay out of the boost it should be 30+ mpg.
The difference between the auto and manual is drastic. I was pretty disappointed with the auto in 2nd gear when I test drove it. Again, an MBC will help, but not as much. Wife doesn't drive stick?

Anytime you improve air flow, be it intake or exhaust, you will see an increase in HP and fuel economy. When I had full exhuast put on my '87 Toro and built a K&N cold air intake for it, my mileage increased from an AVERAGE of 18mpg to 20mpg and that's mainly short trips. I can only imagine how much better the cruising efficiency of the WRX will become!Penguinking said:
