2006 Outback LL Bean Wagon H6
5600 miles so far.
Average MPG is 16.73855 after 28 tanks of gas. That also includes mixing between premium and 89 grade gas. Mostly premium though.
 
Worst mileage = 13.31
Best mileage = 23.14 (on 48HRS run)
 
My driving is a mixture between highway/city with LOTS of stop and go.
 
Hoping for some improvement as the engine gets more broken in.

You should see an improvement, she's still very green. My mileage did not reach it's peak until 15k miles.

That's what I figure. I've also started driving a bit more conservatively. Also just keep the AT in "regular" drive. I noticed a mileage improvement from when I kept it in Sport mode (although not as much fun). Hopefully, in a few years, Subaru will have a 6MT H6.

Just returned from a trip to Gatlinburg from Cincinnati...
 
31.5 mpg. actual overall including a trip to Clingman's Dome in the mountains. 34.5 mpg on the road at 65-70 mph. I am a bit surprised at these numbers but they are real.... and I expect they will improve a bit(only 2200 miles on the car) The mileage drops significantly when having fun with the sportshift... :-0 oh well.....

tima3, those numbers are real. I have a 2005 legacy 2.5i wagon auto. I reset the trip odo B when we went to Cololrado last summer. I got 30 average for 5000 miles. I never reset it and the car now has 28,000 on it and for the last 17,000 I have gotten 25.8 mixed mileage. Recently I went to Terre Haute and back (220 mile round trip). The speed limit is 60 and I obeyed it and got 34 mpg. I get about 32 at 70 mph when I go to nashville. I am now getting 23 city. My good mileage began really at about 20,000. All three of my previous Subarus got their best mileage beyond 20,000.
 
It's not a hybrid but I'm thrilled with the mileage.

I confess, although I bought the car because of what's under the hood, I drive like an old woman in order to get the best fuel economy. Although on occassion I will call upon the rocket power of this fine turbo engine, I'm usually very, very light footed with the accelerator. However, I don't corner like an old lady, and I do take advantage of my powerplant's torque in some aggressive cornering.
  
I drive mostly country/rural driving and interstate highway (I live in the Northern Catskills/Mid-Hudson Valley region of New York). I rarely exceed 65 MPH on the interstate in an effort to increase fuel economy. On long downhill sections of roadways, I often shift into neutral to lessen the engine speed and gas consumption.
  
My old lady habits pay off with good fuel economy. My vehicle is EPA rated 19 MPG city/25 MPG highway. I tend to average 25-26.5 MPG with 90% rural/country/highway driving. The remaining 10% of mileage per tank is often stop-and-go traffic in suburban New Jersey and driving in evening rush hour traffic in Manhattan/NYC. If my driving excludes NJ/NYC rush hours and is completely rural driving, I can get 26-27 MPG. On long highway stretches of non-stop driving using cruise control, I can usually get 28-29 MPG, once even 30 MPG, as long as I don't exceed 65 MPH. All of these figures are mathematically calculated. I find the car's computer is usually overly optimistic by 0.8-1.5 MPG.
  
My car, in non-winter months, is equipped with Pirelli PZero Nero M+S tires which I usually have pumped up 2-3 PSI above what Subaru recommends, which for my car is 35 PSI front and 33 PSI rear. These tires have a fairly high rolling resistance, especially in comparison to the OEM Potenza RE92 tires (but they handle so much better!). I normally travel alone in the car without any passengers with the exception of my dogs. My winter fuel economy tends to be lower, attributable to the use of winter tires, winter fuel composition, and colder operating temperatures.
  
I fuel my car with 93 octane fuel mostly, but when 91 octane is available (most Sunoco stations) I will often purchase that if it saves me a couple of cents per gallon (my turbo engine requires 91+ octane).

2004 IOBS ~27 MPG by subi4obs

2004 Impreza Outback Sport 2.5L and 4 speed automatic.
 
27 MPG for overall average (since around 10 to 15 thousand miles).
 
Mostly rural/highway/freeway driving, very little stop and go. Only driver (me, of course) and some gear in car. Original tires (Potenza) usually kept as close to correct inflation as possible, 32/29 PSI F/R. Been using Mobil 1 synthetic engine oil since about 1000 miles on odometer, which is currently over 26 thousand miles. Run only 87 Octance regular gas, cheapest I can get-- annoying pinging included.
 
Almost forgot to add... I'm a heavy user of Cruise Control.

Interesting, I have a 2000 Outback wagon and though I buy name-brand gas, I've also been having trouble with pinging. Has your OBS always done this or only recently? I think it might be the switch from MTBE to Ethanol.

It worried me a lot at first because I discovered the manufacture date was Feb. 2003, as stated on a doorframe plate, which I somehow overlooked when checking out the car before buying it off the lot. I got the car "new" in Sept. 2004, so that seemed a very long time, odometer read 28 miles after a short test drive.
After realizing that the car must have spent a long time on the lot (actually came from Nashville, TN, about 100 miles from local dealership) I drained the gas tank to get any trapped bad gas out of there (are two sides to these, as you may or may not know, so that meant opening two different plugs). Then I changed the fuel filter. Well, I finally noticed the car will ping most when the gas tank gets below 1/2 full and especially if only at 1/4. Gas treatments were tried but I hadn't found any remedy by doing that. I think maybe higher octane helps but I only gave that a try twice.
I almost always get gas at either Raceway or Pilot near home. Haven't checked into what percentage of other stuff might be mixed in. I think the majority of pinging-- aside from that caused (supposedly) by the tank levels-- happens only during acceleration and steady uphill climbs.
Oh yeah... another thing too... there's also occassional high-pitched plunk noises during sudden decelerations (just once each time). Doesn't happen everytime but enough to be a bother to me. Sounds like a metal sheet being hit lightly under the car. I've found out that's possibly something about extra gas igniting in the exhaust pipe near the catalytic convertor, maybe, which is something I need to talk with the service people about when I take the car in for its 30K mile checkup.
Another thing I had a lot with this car is the awful sulfur smells, another thing said to be about catalytic convertors having trouble with burning fuel cleanly enough or whatever. I don't know much about it, just what I've read or heard said. Luckily those are few and far between anymore, yet seemed to happen a lot during the first year or so.
Thanks for asking Eric, hopefully not too much info given. I really need to get a look at the Ethanol, MTBE stuff when I'm at the gas stations!
