First fill-up today. Miles driven (which for this was odometer - 15 miles)/gallons filled netted me ~27mpg combined city/highway, about 11 gallons.
This range would've starved the STI about 40 miles back and taken up an entire 16 gallon tank and then some.
I'm happy! Most efficient subie I've owned. WRX and Forester never had this kind of combined efficiency, and obviously the STI never even came within sight of it.

and sip gas, folks... more money for
