That's very good given the size and accounting for it being AWD. I bet you beat or match a tiny Suzuki SX4.

Thanks, xwesx I'll see if I can do the PCV valve myself, and ask my mechanic if he has a test for the O2 sensors before determining if they are the issue.

Well, I read somewhere that 55 MPH is usually close to the optimal MPG. Every 5 MPH over 55 MPH you travel I think you lose 10% fuel economy. Something along those lines, I think it was on some US Government website. Maybe Department of Transportation / Highway Safety. Anyway, again, the 36 MPG is skewed because it doesn't take into account idling and things like that. For example, the day after when I turned the car on, I gave it about a minute to idle before I put it in gear, and the MPG decreased to around 32MPG. Granted, this also increases once I get the car back out onto highway.
I'll have to pen-and-paper some MPG next time I fill it up, since I use the same gas station on my way home from work and we'll see if it corraborates what my trip meter says.
Who needs a hybrid, just use your damn cruise control and try driving close to the speed limit!

Who needs a hybrid, just use your damn cruise control and try driving close to the speed limit! On the highway yes. But in daily city driving, I'd take a hybrid any day. That's where they shine.

If your trip computer is anything like the trip computers on the Forester and Impreza, you'll likely find that it is between 1 and 1.5 mpg on the optimistic side.

That is typical, but I had a Tribeca for a week, and oddly enough it read 0.6mpg LOW! Strange.

I have mad my 11 outback since Oct 1. For first 10,000 miles, I did not reset one trip odometer and it read 28.2 mpg. I am now over 9000 miles since then, and, again, it reads 28.2 mpg. I always fill the tank myself, and always "top it off", so I know my actual mpg per tank are very accurate. Probably cutting it too close, on three occasions I put in 18.5 gals, one time 18.9 and the tank is supposedly only 18.5 gals. At any rate, when I have a chance I will add up all the gas I have purchased for this vehicle since new (I keep good records) and I believe it will come out to just about 27 mpg, actual. Yes, everyone's statements about mileage indicated on trip comuters being optimistic is correct. I have had many vehicles past 20 years or so, and every one of them is "optomistic, and this includes a 2005 outback, 2006 Tribeca, 2009 Forester, as well as my current vehicle. I would say the actual mpg usually 1 to 1.5 mpg less than computer indicates.
That being said, I have averaged, per trip computer around 31 to 32 mpg on a few occasions, but the best actual mpg I have ever attained (on mostly highway driving) has been 30. If, near the end of a long trip I must fill up, then continue home for another 30 - 40 miles, I have seen the computer go as high as 34 mpg. I think that's because the previous many miles were all highway, as well as the portion of the trip back home.
However, if I start up following morning & it still says 34 mpg, after just a few miles, it will drop very quickly.

The tank may be that size. If you topped it off, portions of the rest could be in the fuel filler neck itself.

**If your trip computer is anything like the trip computers on the Forester and Impreza, you'll likely find that it is between 1 and 1.5 mpg on the optimistic side. **That's right on the button for my trip computer. My 2011 Legacy 2.5 has been in the 25-26 MPG range lately (30/70 city/highway - calculated as miles driven/gallons to fill up), and always about 1 to 1.5 mpg lower than what the trip computer says for that tank. I have been getting better mileage since the weather warmed up, but not as good as I expected based on EPA MPG figures. And I've been babying it, trying to get the MPG number up. I'd say the MPG is my biggest disappointment with the car.

I really don't look at the MPG readout on the dash, but my '10 Legacy gets consistently over 30 MPG (34.4 more than once) when all freeway. When I mix in city driving it drops, but not as low as yours. I might not actually ever get as high as 30% stop and go drving on a tank so that might be part of it. Recently took 2 long road trips, Colorado to Cincinnnati and Colorado/Austin TX. The first was with 2 adults, suitcases, one set of golf clubs etc, 2 tanks were above 34. The second was one adult, tools, golf clubs etc and the worst tank was 32 and a fraction. That's at 75 MPH with the cruise control.
Turned over 31,000 miles on the Austin trip.
