2009-10-28	2.1	0.0363		57.85	My first on-the-road test, stop-and-go on residential streets. MPG data is from the onboard instrumentation. Still waiting on parts to fix my coolant leak, otherwise I'd have gone much farther and faster.
2009-11-02	107.5	1.215		88.48	AMEC IV. It was a mostly flat course, not conducive to hypermiling. I spent most of the course in gear at 40mph (~1400RPM, in lean burn), or idling in neutral on longer downhills. I used my IMA inhibit switch well, but I didn't have an engine kill switch. My CdA was higher than original, because I'm missing some underbody panels. I'll fabricate something before my next road trip (Thanksgiving).
2009-11-02	243.2	4.208		57.79	Return from AMEC IV. During portions where I slowed down enough to stay in lean burn (68 on level ground, faster down hills, no lean burn up hills), I got 65mpg. That's a tiring way to drive, so mostly I just floored it and targeted 74mph. I will have to improve my aero and IAT to enable lean burn at 74mph.
2009-12-01	570.8	9.342	$2.899	61.1	My first real tank in the Insight. Bad thermostat, summer tires.
2009-12-28	496.1	9.648	$2.819	51.42	A disappointing tank. Winter tires, cold weather. Fixed my thermostat halfway through the tank. Even though it's only getting colder out, I think the next tank will be better.
2010-01-13	560.2	9.811	$2.999	57.1	It's cold out there.
2010-02-05	537.4	9.946	$2.919	54.03
2010-03-03	556	9.586	$2.899	58	This tank started with lots of 50-60mpg commutes, and ended with mostly 60-68mpg commutes. It's getting warmer! I'm itching to put my high-performance tires back on, but that would be premature.
2010-03-26	558.2	9.076	$2.999	61.5	Mounted my summer tires a few weeks into this tank. Spring is upon us.
2010-04-21	604.6	9.506	$2.969	63.6	Still getting 40-60mpg on the 1.5-3mi trips that I make around town, but I've been seeing 70 and 80mpg commutes with increasing frequency. Next tank will be awesome?
2010-05-08	654.4	9.539		68.6	This tank started off with consistent 70+mpg commutes. 423mi in, was at 70.9mpg. Then I drove 74mph in a crosswind+rain to the Green Grand Prix, at 52mpg. 79mpg after leaving the interstate, then 87mpg during the fuel economy run.
2010-05-21	553.8	9.139	$2.819	60.6	This tank includes the 150mi/45mpg trip back from the GGP in severe winds at high speeds. Also two weeks of ordinary driving, and the first leg of my trip to Indiana.
2010-05-24	571.2	8.302	$2.619	68.8	100% interstate travel. Only willing to slow down a little for the sake of fuel economy.
2010-06-14	660.2	9.868	$2.899	66.9	This tank includes 331mi of interstate @ 65mpg, and 329mi at 69mpg once I got home. Used about 10KWh of electricity as well.
2010-07-15	609.8	8.517	$2.799	71.6	+15KWh.
2010-07-16	708	9.725		72.8	Buffalo NY to just shy of the IL/WI state line. My goal was to make the 699mi trip on one tank, and I would have done that had I gone straight from Buffalo to Madison. Kinda fast, very warm, one window open.
2010-07-19	679.5	9.333		72.81	The middle third of my interstate trip. Kinda fast, awfully hot out. Next tank will include 271.4mi @ 75.6mpg of interstate travel.
2010-08-27	719.2	9.513	$2.829	75.6	Plus 20-30kWh.
2010-10-31	722.1	10.31	$3.099	70.04	Three months of city driving. ~70% of this distance was on roads with PSL at or below 40mph.
2010-12-01	652.2	9.808	$3.119	66.5	Plus several KWh. Winter arrived the day after this fuel-up.
2010-12-27	512.2	8.452	$3.199	60.6
2011-01-26	556.5	9.229	$3.319	60.3	60mpg is good enough, and this tank is barely good enough. Good news: this is the worst winter can throw at me. It's downhill both ways from here.
2011-02-21	546	8.98	$3.289	60.8
2011-03-23	560.6	9.042	$3.699	62	Just another winter tank.
2011-04-14	527.5	8.32	$3.899	63.4	Filled a little early, on the way to Watkins Glen for the GGP.
2011-04-28	620	9.538	$4.039	65	Includes the GGP, the ride home, and two weeks of commuting.
