I've been tracking mine in my Owner's Journal Post 1 since I purchased the car (6AT) in 05/2012.

Results so far:

77,057 miles. 198 Fuel Stops.
Average Mileage Overall (Calculated): 32.72MPG
Average Mileage Overall (Computer): 33.80MPG
Average Fuel Cost $0.10 per mile.
Best Average: 36.6MPG (All Highway)
Worst Average: 27.6MPG (About 50% stop and go city)

Most of my travels is commuting which sees an average speed of around 45MPH.

With the original Primacy tires I averaged 32.65MPG (around 62,000 miles). Surprisingly, once I switched to Bridgestone Ecopia all-season tires (@15,000 miles) I've average 33.40MPG.

I've also "saved" $5,184 and 1,655 gallons of fuel over my previous daily driver that averaged around 18MPG even when adjusting for the difference in regular vs premium fuel.
