I do the same: like going down some big hills around here, in DFCO, I'll crank it to the max, pulling that same hill later in the day I'll turn it off. It will stay coolish for a while after turning it off, But when it's REALLY hot, screw it, I just leave it on! I am especially liking my WHITE tinted window Yaris, it is everything I hoped for summer driving, cool and cheap to operate. 46.96 MPG last tank.

It's crazy not to use your AC, unless for some reason you like to suffer or prefer having hot air blowing in your face with the windows down.
In a Yaris, it's costing you not even one penny per mile to be comfortable with the AC on. In fact, right now at today's gas prices, it only costs about 8.5 cents a mile to drive. AC on might raise it to 8.7 cents per mile. If one is too cheap for that, sell your car and stay home. For comparison, 4,000 miles during 3 months of summer driving with the AC on = about $80 extra (for AC). That's a rough over estimate but just gives you an idea. $20 a month is well worth the luxury. |

Having a Scan Gauge makes it pretty persuasive to use the air when needed, but not more then that. I don't drive around sweating, but I do give a little thought to big upgrades and downgrades, and mine does DFCO when the air is on, according to the Gauge anyway. It hasn't got real hot here yet also, when it hits triple digits I'm sure I'll say the hell with it and just leave it on! But for the more moderate temps I am cheap enough to use it sparingly, while still staying cool, best of both worlds there! For sure the dollar cost is nothing, it's more being super efficient I get off on, and why I drive a Yaris to start with.

My AC goes on anytime it passes about 70° F. Warm air is unacceptable to me.

I just drove from Indianapolis to Chicago.....74 MPH and stopped to gas up....just a hair over 40 MPG with the AC on the whole way. I think it is foolish to not use the AC!

The higher the fan, the more fuel you will burn. This is because the higher the fan, the quicker it will remove the heat from the condenser, whereby lowering the compression and causing the compressor to come on again and start compressing freon.
Recirculation saves fuel because your cooled air in the cabin is recirculating and you are not trying to cool down the outside air as it happens in the fresh mode. More electrical load does use more fuel. That is because the alternator will create more resistance on the belt and crankshaft making the engine work harder and burn more fuel. Turning the heater does nothing as it only opens the hot coolant of the coolant system and lets it go into the heater core in the dash... if anything, it may prevent your radiator fan from turning on, thus reducing the fuel consumption. Dont power anything from the batter if you can help it, it's only designed to start the car and provide emergency power when the hazard lights are on or you need to turn on the lights in the cabin. |

I just got back from a 4500+ mile trip in 14 days. I ran the A/C the whole time, pulsing on and off as needed in the mountains. Used cruise control at the speed limit plus or minus a couple mph depending on conditions. My lowest tank (let friend drive half of it) was 37mpg. My highest was 42.8mpg.
