2012-06-20	1519.8	21.37	$3.679	71.12	"I may start just subtracting 1 mpg from my readout. Every tank since I bought the car has been 1 mpg optimistic except for one 0.7 that may have been my error. If it's that consistent, it will save me the trouble of calculating it. Still, gotta love summer mileage!"
2012-08-03	1689.2	22.28	$2.529	75.82	"Best ever. Long trips to Lake Erie and hot weather helped. Kroger fuel perks are why my gas was so cheap. Fortunately, this time I got it befor gas went up (for once!)."
2012-09-16	1779.3	23.9	$3.549	74.45	"I'm afraid I am on a downslope for FE until next spring. The cold weather is making it harder to get the mid 70's. I have numerous mods on the way and/or ready to install, including manual control of the hybrid system (or MIMA for us Insight guys), a block heater, and a dumb charger for my NiMh battery made from some 90v, 300maH LED light power sources. Many thanks to the minds at insight central forum."

2013-02-20	674.2	10.927		61.7	"Winter sucks! I fight to stay over 60mpg, whereas 70 was a bad tank during the summer. My bettery still functions and doesn't throw codes, but it isn't putting as much amperage out as it used to. I know this thanks to my newly installed OBDII C&C, a Scangauge type device that also tells you what the hybrid system is doing."
2013-03-14	707	11.2	$3.999	63.13	"Bought premium for next tank out of curiosity after reading an insightcentral.net thread. I don't expect much in the way of improvements, but I thought I could at least watch the timing advance and AFR to see if I could notice any change. It is amazing how much difference winter and summer make in this car. I see about a 12 mpg difference. I rarely use the HVAC either time."
2013-04-06	675.8	10.208		66.2	"Maybe it is just the placebo effect, but 93 octane has helped me considerably. I theorize that greater knock resistance lets the Insight run in lean burn at a load that would drop out of lean burn on 87 octane. 22:1 is way better than 14.3:1, even with the greater throttle opening needed. I think this helps the Insight much more than the hybrid drivetrain. If so, it is enough of a gain to justify the cost."
2013-04-18	738.8	10.52	$3.63	70.23	"Still using premium. Even if it is the placebo affect, I am getting a mileage improvement big enough to justify the cost. My theory is that cold weather cost my Insight some spark timing, and high test gives it back. I imagine the advantage will go away as it warms up."
2013-05-10	716	10	$3.929	71.6	"Still premium fuel. I may be headed for worse mileage, but I am hoping good weather will offset it. My tires are about wore out, and the Re92, if I can find them, have a break in period for truly good mileage. Still, good tank."

2013-06-18	738	9.76	$3.929	75.61	"Learning to let off the gas to kill the lean burn purge has been a big help. Next I need to install MIMA and clean and/or replace the EGR valve."
2013-07-03	760	10.15	$3.329	74.88	"JUST missed another 75 mpg tank. I had a forced recharge and city driving doomed me at the end. My battery is on borrowed time. I am not getting IMA codes due to grid charging/balancing, but its capacity is way down. I need to replace my EGR valve and I need to install MIMA, preferably before I leave on vacation."
2013-08-31	774.8	9.7	$3.819	79.88	"Summer heat, almost all driving in my very efficient commute, a new EGR valve, and I get my best tank ever."

2014-02-18	587.9	9.79		60.05	"I HAAAAATE this winter! Snow tires and cold weather forced the car into battery heating mode. It kills mileage."
2014-04-14	648	9.8	$3.55	66.12	"Back to decent weather! My battery is dying though. It doesn't have much capacity left, and if it recalibrates low into a forced charge, that sets off a p1449 (basically a hot battery). I have learned to drive without assist for more than about 5 seconds at a time. I just paid her off, so I think a new battery is coming."
