[MetroMPG]

HAPPY to report the first fill in the Civic (admittedly a smallish fill at ~5 gal) came in at 49.7 mpg US = 4.7 L/100 km = 60 mpg Imp.

This was about 25% sub/urban driving and 75% back roads highway ( I killed the engine approaching most stops & many turns). 50% of the highway portion was a trip made this weekend where I just set the cruise control at the scenic route speed limit (max. of 80 km/h = 50 mph) or a hair under if nobody was behind me.

Using cruise at that max speed, in those conditions (cool @ 8C / 46F, little to no wind, light drizzle half the time), the car seems capable of delivering ~50-53 mpg US, round trip.

More where that came from: And the thing is, I rarely use cruise control in my usual driving. That means there's a bit more efficiency to be had from DWL/target driving (my usual approach).

ScanGauge update: looks like the uncalibrated gauge was optimistic by ~10%. I'm going to wait for corroboration from Phil's Civic this week before adjusting the numbers in the graphs I've already posted.

Next up: adding an engine kill switch, reproducing the rear deck lid spoiler in coroplast, and fitting the trailer hitch/receiver.

I'm really pleased with this car. It's going to be waaay harder to get great city mileage than the Firefly -- you can't easily defeat mass, but it will do quite nicely on the open road at moderate speeds.
