Default STi gas mileage..

Wondering what other STi's are getting for gas mileage? Please list the average number of miles you get on a full tank fo gas and any power mods you have...especially interested in stage 2 STi gas mileage.


My STi is stock and I average about 260 to 280 miles on a full tank (city driving)

With the green I was getting about 18-19 mpg.... Maybe 250 on a full tank but thats sooo subjective because the amount that goes in vs where your fuel light comes on ect ect... I think my tank floater is a bit bent from the fuel pump swap...

After the gt30r I got one tank about 15 mpg lol.. I was having a lot of fun with it The most recent tank has been all freeway miles mainly and it looks like I'm going to pull about 290 miles out of it City driving I'm expecitng it to be aobut the same as it always has.. 250 or so until the yellow light comes on... Different mods haven't really made it much better or worse - unless I end up playing with the go pedal more

Mods - PE 850s, Hydra, Perrin GT30r, Full 4" intake w/ no MAF, walbro, stock cat-back, Txs TMIC, ect...

25 mpg on the highway with K&N Typhoon

Now that I'm Stage 2, I've been having too much fun so I can't tell you exact mpg. I should be able to this weekend tho.

Yea with a catless dp and intake I noticed probably a 2mpg increase when I drove fairly conservative which is synonymous with NEVER... Update on my latest tank - its at 300 and needs fuel asap. This is with a drive from burlington to tacoma with 30-40 minutes in stop and go traffic. The other 1/3 of the tank was city driving mainly. Probably the best I've gotten in months so I'm hoping its a sign of what the new setup will do

The difference I notice between stock and now - stock I could get on it all the time and it'd only drop maybe 1-2mpg. Now if I get on it all the time I drop from ~21-22mpg to 13-14 mpg lol...

i usually average around 20mpg. or just shy of that. I drive hard though. I fill up at 1/4 tan left regularly. just my thing. i usually shoot for right at 200 miles at 1/4 tank. IF i let the cruise handle it. Long trips it'll get 24mpg. actually, i think when i went to cobb stg 2 i lost some mpg. even on long hiway trips. I have never tried econo mode. been too afaid of it leaning the cylinders out and one time when someone wants to push their luck w/me rolling down the hiway, id stomp on it and destroy my pistons. Im really afaid of detonation. i dont want to put pistons in my engine. Mainly i dont want to deal with my wife when i tell her my brand new 04, the engine is broke. I have only 13k on it. id hear it for the rest of my life.

so my answer would be about 24mpg letting the cruise handle it. wayyyy less than that when my lead foot gets control!

I'm bone stock. My mostly urban with some highway driving is giving me poor mileage. I usually fill up early as I've had a bad experience with running out of gas once in the past (partly could have been bad gauges). Usually, I fill up about 14 gallons or so (tank is 15.2 in manual if I remember correctly). I had some fun on a tank and got a little more than 200 miles, which was bad. Then, this last tank, I tried to take it easy and not speed up really fast or hit high rpms often and still only got 226.1 miles (fill-up after this distance was 13.983 gallons). That's only 16.17 mpg, which seems abysmal given the way I drove. Maybe, if I go for economy on this next tank, I'll try to not rev match downshifts and just use the brakes more than the engine along with even more conservative driving. Maybe something is wrong, but does mileage get better with more miles on the car? I'm a bit over 3,000 miles and haven't done my first service yet.

PS: Debating whether to service where I bought the car at Royal Moore in Hillsdale or if I should go to Wentworth where I may have bought the car if they had my color.

I'm not convinced it's all driver. I'm at stage 2. Been there for awhile, got used to it. I've been trying to short-shift and run low RPM's lately. Trying not to use the throttle as an ON/OFF switch.

Best I've been able to muster so far is 18 MPG. But that's city driving (highway or not, it's still stop-and-go around this damned place).

Thumbs up

Just got an 2006 STi and Iím going the whole vehicle brake-in period thing for the first 1,000 miles and I keep the RPMís under 3,500 and I just filled up yesterday and got 21 mpg. My STi is stock and I average about 260 to 280 miles on a full tank (city and highway mix)

city and highway (mostly city)..lots of stop and go's with a fair amount of WOT blips...been getting right about 200 miles on the 3/4 tank then I fill up so thinking I am right about 270 miles on a full tank like above (roughly 18 mpg's), this has been fairly consistent number for me...scary to think what some 850cc injectors are gonna do to that number!

Heh! Still can't believe how many cars are on the road - It's even clogged up at midnight... I'm in the 18 - 21 range - Usually fill up around 260 miles w/ Cobb Stage 1.

I got 306miles on mine last weekend. Of course, when I turned into the gas station, the car sputtered a bit. Oops.

I filled up 14.4 gallons (I really, REALLY wanted 94 octane.)
