I don't think he drives with fuel economy in mind.

Nah, it was just one trip. Using Torque wouldn't help, I've logged stuff with it before, the onboard average mpg calculator is far more accurate at figuring out total fuel usage. An OBDII reader only captures instantaneous mpg at fairly infrequent intervals.
Using this method, I've been calculating ~90 mpg in "city" driving. For 2.5 miles, the engine only runs for 0.5, and it indicates mpg in the high teens. Seems about right, that's around what the champ P&Gers like PaleMelanesian get. If I keep the engine on the whole time, it'll plummet to the 20-30 range.
The freeway part is more like 45 ish, which is still pretty solid.
