Real world gas mileage: Ford Fusion

I’m giving a Fusion every time the Expedition is in for service (usually an I4). I get (according to the gauge) 31 mpg in mixed driving (heavy traffic for about 30 minutes, then 100 mph on the toll road for 30 minutes, then 10 more minutes of heavy traffic).

That’s not too bad for my driving style. The Expedition only gets 12.8 mpg.
