[Overdrive]

Only have 4 tanks under my belt so far, just getting past the break-in mileage, and I've been kind of all over the place for economy, between 24-27mpg. I've found the car's average economy reading to be overly generous every time so far, sometimes by a whole mpg or two, and I was already in the habit of doing it myself using a trip meter, so we'll see if it ever syncs up with what I calculate. For now I don't trust it.

I also have a suspicion that the car was filled with regular (87 octane) when I took delivery, so I was careful with it until I ran the first tank down to fumes and put in a full tank of 93 (although we have 10% ethanol around here at virtually every station). Most of my driving lately has been local (mostly city), commuting (about 2/3 hwy, 1/3 city to work, mostly city coming back home to avoid traffic jams on the highway), and a little joyriding here and there that's anything but good for fuel economy. I've yet to get a chance to take it on a long highway jaunt where I can cruise, and with winter coming I'm sure I'll take a big economy hit, but since I have an automatic I think I'll end up doing pretty well for long highway trips when the weather gets nicer. Mid-30s from a sports car running premium fuel will be pretty awesome to see.
