Default Using AC seems to significantly impact MPG.

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

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.
