Using AC seems to significantly impact MPG.

[firsthonda]

When I use my AC, depending on where I drive, I loose anywhere from 4 to 10 MPG. Without AC, I typically get from the low 40's to mid 50's. With AC, I seem to get low 30's to mid 40's; on the same routes.

Use ECON mode as much as you can. It will cycle the compressor less often. You'll take less of a mpg hit, but you may be a tad hotter.

I do use Econ 99+% of the time. Maybe I need to turn the AC temp up? I typically run it between 65-68 degrees F.

I keep my temp typically around 72-74. I'll sometime crank it down to 68 but to start out will crank it back up to 72 or 74 during the drive. I find it only effects the gas economy by about 1-3mpg.

On my 250mile trip from Pittsburgh to Maryland, I pretty much kept the AC at 72 and still netted >50MPG for the entire ride.

Today, I ran the AC at 74. It kept me adequately cool and it did help fuel economy quite a bit. It seems that with the Insight, the AC affects MPG in city driving quite a bit more than highway.

Myself I cant break 56mpg with ac. Without ac I can hit 67mpg.

I find its the coldest on the lo setting, auto with econ off.Use of sport mode ust wastes gas.

i always keep mine to the lowest
is that bad???

idk but everytime i use it for a 40 min drive on the freeway i feel like i didnt use that much gas
but then i start drivin street i feel like the little gas arm goes down faster

I find the auto setting works best and 73 or so if its just me in the car. My passengers like 68 better.

[cheesie]

so certain temperatures actually help the mpg??

Yeah, its two fold. One setting saves fuel in stop n go traffic. Another when its set closer to the outside temp saves while cruzing.
