A/C usage strategies to maximize mpg

Look at the feedback lol
Toss out the BOGUS infor from those that could give a crap about Eco than
toss out those that have never tested it and guess what you have?
ohhh How do you know that applies to a Fit?
At speed A/C off windows cracked was the best way I could get mpg.

At 105F no A/C and cracked windows isn't a good idea.

same with my girlfriend!
anywho....
I honest to goodness hate the a/c in this car not only does it practically do nothing (until somewhat recently) it kicks the fits @$$ when its on. Drives like a drunk donkey!
When in the rare instances I feel like torturing myself I turn it on and just coast in gear to the stop. Then just leave the fan on (a/c off) on low to keep it bearable.
But when its hot my fit drives like poo anywho (there I said it! yes my Fit is pissing me off now!) ...but when its behaving I luv it and wanna hug it!

there is no way your going to gain mpg when useing the a/c. but you can greatly cool the interior of your car after its been sitting in the heat by: turning the fan on high, a/c on, recirc. off . so you draw the air from out side. this works best because the air outside is alot cooler then the air inside the car when you first get in. so cooling the less hotter air will be easyier then cooling the hott air in the car. thats less work on the a/c system. once the interior cools down switch it to recirculate. it makes sence give it a shot.

As for the first, heat exhaustion will vary from individual to individual, but again, the effects will be felt by everyone.

The AC uses about 1 HP at lower revs. Your engine uses about 4 HP just to idle. So running the AC at idle adds another 25% to engine load and noticeably reduces city stop & go fuel economy. On the highway, you car uses about 15 HP to cruise, so using the 1 HP AC on the highway adds only 6% to the engine load (or about 2 mpg worse fuel economy with a Fit).

I was driving around the San Fernando Valley (Los Angeles) today, from 11:30 to 1:30. It was pretty damn hot. I rolled with no A/C but with the left front and right rear windows cracked 2-3 inches. Try it; you'll be amazed at what a nice cross-breeze that creates.
When my wife is in the car, the A/C is on. At least she is putting up with my driving like a grandpa now. Even on tanks that were part A/C, I've still been getting 42.

My 94 RX7 had a really cool device I want to add to my fit.
A vacuum operated switch for the air conditioning compressor.
Of course when you stomp on the gas, engine vacuum drops, so this switch would turn off the compressor clutch under those conditions.
Under cruise or deceleration vacuum goes high, then it would turn on the compressor clutch provided the thermostat calls for it.
Thats a little bit of hybrid theory in use there, making generating power more efficient, and using deceleration, which is basically wasted momentum for comfort. In this scenerio you are putting wasted energy to good use to stay cool on a warm day.
The RX7 used the vacuum switch it to make the car faster obviously, and it would make a Fit faster too (when the air is on) as a bonus!
