If the winter was not harsher, then it is highly likely that there was a new blend being used. In what part of the country do you live? If winter temps are significantly cold (less than +20F on a regular basis), you can improve winter economy by switching out the stock gear oil with a synthetic 75w-90. Replacing the power steering fluid with a synthetic can also help.
#129 of 130 2010 Outback = 29 MPG on the cheapest gas! by boxerpluscvt

My 2010 Subaru Outback (4 Cyl AWD CVT) has been averaging 29.2 MPG for the last 9 weeks / 3,500 miles. This has been in 50 - 70 degree Spring weather with 80% - 85% highway driving through three northern NJ counties and one trip to midtown Manhattan.I don't rely on the built-in computer for this data. I run out each tankful of the cheapest "no name" Regular gas and zero the trip odometer each time. I'm writing this entry after getting 31.16 MPG - 561 miles on 18 gallons of Delta Regular.
By the way, after these 561 miles the MPG mid-dashboard computer said I had averaged "33.0" miles per gallon for this tank of gas. Having tracked dozens of tankfuls, the Outback's MPG computer makes sense only if you subtract 6% from its number. ("33.0" x .94 = 31, the actual mileage I was getting.) For the Outback owners out there, after filling the tank the Range computer displayed 620 miles which computes to 33.5 mpg. (Maybe one of you wants to attempt that?)
I drove as conservatively as possible to get my 31 mpg. I also run on Mobil 1 Synthetic oil and had the emissions software update that came out last year. Though some bloggers said the update hurt fuel efficiency, it has had no effect on mine.
I've had some great cars in my life - at least a dozen - and this one is my favorite. I test-drove all the small SUVs and wagons - from Cayenne to TSX - and I made the right choice buying the Outback. At 35,000 miles it's been a pleasure to own and drive.
