We can break 30 on the highway once it's warmed up.
Short trips kill mileage - before it's warm especially.

Thanks. I thought that might have something to do with it.

turn the ignition to the first click and hold either the - or the + on the clock for 5 seconds.

I get 32-33 hand calculated highway with my 2004 xs 5 sp manual. I keep it 70 or under. It's great- I went from a 98 corolla and didn't give up much- cant imagine getting less than 30 on the highway...

i kept a written record of my gas logs re mileage the first year but it hasnt changed - in the winter i average 200 miles on 14.5 gallons (the point at which my light comes on and i pull over and fill up at freddies).
summer is not much better - 300 miles on 14.5. after my memorial day speeding ticket - who pulls over a subaru forester?? i have kept my speed about 60 mph. no change in fuel economy. the only thing i can attribute to my terrible mileage is that i have a bike and ski rack on top. but still.
my commute is 26 miles to and from work. no luck there either.

Both of those are still very low, for sure. My '10 is now at about 47.5K miles, and it's running average is still about 23.5 overall. Unfortunately, I lost about 1 mpg during the summer months this year when I replaced the stock tires with a set of Goodyear Assurance TripleTred tires. I had a set of those on my '96 Outback and used them year-round. They were the best all-season I've ever used during winter (really quite decent, though not as good as dedicated winters), plus they have astounding treadwear. But, I also lost some fuel economy on that car (or so I felt I did).
These new ones are re-designed, and Goodyear noted that they specifically improved the FE characteristics of the tire. But, apparently not that well, given that they still cause a substantial FE drop (which I know for sure this time because I now keep logs on all my cars). I was bummed, but at the same time that was not my primary requirement when I bought them. During winter, I'm still using the original UGI's, which are now on their fourth winter at 8/32" tread depth.
Winter FE is running 20-22 depending on the temps.
Your commute isn't the problem. Idling might be somewhat of an issue during winter, especially if you're at ~14 mpg in the winter.... really?! Did you buy at Kendall? I ask because I'm wondering if it is fully winterized with good low-flow lubricants. Drivetrain resistance can cause a substantial drop, but then that still doesn't explain summer. Your rack will definitely cause a drop.
Cross bars, all by themselves, will knock off a solid mile-per-gallon. Round cross bars, if you have those, will possibly take more. An odd shaped accessory up there like some bike or ski racks could likely hit you for a couple more. Unless you're using them all the time, I'd try some time without those up there to see what it does. Also, if you actually carry a bike or skis up there, that will hit you more... esp. the bike!
When I carry stuff in my cargo basket on top, or even just the basket alone, I only get probably 22-23 mpg during the summer, vs. 26-27 without that up there. It's really a huge hit.
