I filled up again today (38.2mpg, 456.7mi, $3.099/gal) and it looks like my mileage is levelling off around the 38mpg mark. Part of this is due to evenly divided commuting and highway driving, and another factor is that my technique is much more consistent than it used to be. There's no reason to complain since that's a 27% improvement over what I had been doing for the previous 8 months. My goal is to get that number over 40mpg in another month or two. Definitely possible. Some promise lies in the commute from my new apartment, which starts next week. It's a bit longer(20mi), it's on the highway where this car shines, but traffic could get pretty nasty in the afternoon if I don't time it just right. (DWB all the way!) It's been warm here, but a little more consistency would be welcome. So I guess we'll see!
