i sell em and i have one - i suggest to NOT set-up to 50-50 on pavement unless its very slick... i have mine in auto and i have been getting 17-19 mpg with 92 octane.(driving moderately hard)
on a side note the auto is primarily set on 35/65 and only adjusts to other settings if needed. i don't really care for the 35/65 to be set manually- sometimes i like the "clawing" effect of all that 300 lbs. ft of torque hitting that pavement!
ironically subaru has not yet released a chart describing all the settings inbetween. i know that lock is 50/50 and the green at the bottom is 35/65. but i'd like to know just exactly what everything elase inbtween is.
getting back to subject- you are actually getting decent mileage if you are driving normal- those numbers posted on your manufacturers sticker when you bought the car are if anything- magical numbers. my only suggestion is this- adjust your shift patterns. -->picture (scroll down)

Gregg's drawing makes my eyes bleed. So are you suggesting going from 1st to 3rd to 5th?

I find it hard to believe that using that much more gasoline makes the air cleaner, but I am sure studies were done.

ok i have 19k miles on my 04 STI and I'm still getting 300-350 miles to a tank using 92 octane. When I'm at the track, I'll still get 250-300 miles to the tank. When I went down to California I was getting roughly 215 miles to the tank with AARCO and around 250-300 with Chevron 91. The most miles to the tank I've gotten was a drive from Spokan Washington to Olympia and I made that trip on one tank of gas 365 miles...but it was close
