What About The AC?
When you have to use the AC, it is worth it to set the blower as low as possible? In other words, does it use more gas to set the fan switch on 4 instead of 1?

No. The fan speed is reduced by simply adding a resistor(s), rather than by an electronic speed control, so the same amount of power is consumed regardless of fan speed.

If it is then I feel like an ass for driving this whole time with the fan on 1 thinking that I was saving some gas, but still uncomfortably hot. Nothing to do with fuel economy, but when you have the A/C on, is it better to have the air on circulation than it is to let outside air in? |

When the A/C is on recirc, you are only re-cooling the already cool air from inside your car, but when you are on not on recirc, you are pulling in some of that extremely hot outside air and trying to get it cool. It is MUCH easier to keep your car cool by using the recirc setting.

Yes. And when you're running the fan more slowly, the compressor (which is what REALLY draws the power) will be running much less. It kicks on and off to keep the discharge air at a minimum temperature.

Yes it makes the air much cooler inside the car when running on recirc. But its also a good idea to run the system on fresh air for a while maybe once a day. Running on recirc for long periods of time will foul up the inside of the climate control system. I think mould and other nastyness grows in there.
Yesterday was the first day this summer Ive needed the AC on. Its been amazing cool here in South Jersey this summer! |

^ and working off of that...
Keep it on recirc until maybe the last couple of miles of your trip so that things do dry out by the time you reach your destination.

Running on recirc will lead to drying of the system as moisture precipitates out of the air on each pass. Open it up to the humid outside air we have here, and it'll produce far more condensation.

Hmm my wife basically destroyed her Honda years ago by constantly running it on recirc with the aC on full blast. The climate system stunk so bad we junked the car. Maybe it was something else...?

I "pulse and glide" my AC when I need to use it by keeping it on recirc and running the AC until it gets cool. Then I turn it off and when it gets too warm I turn it back on again. I try to run the AC on the down hills when I'm mostly in DFCO anyway ("free AC").

No longer keep track of mpg's...as the little car always does well. As far as AC is concerned, if it is hot in the car...use it. Driving in a comfortable temperature sure beats driving around on a warm day and cooking inside a car..regardless how much extra fuel you may use.....better to be comfortable.

You already saved a bunch of money by buying a cheap underpowered jap car that gets good mileage, why torture yourself sweating inside a car youre making payments on? Buy premium too and live a little..my mileage went up 1.5 to 2 mpg in the hot weather just by buying premium, the car likes it under load (I drive hard), live a little cheapskates. |

I own my car, but yeah you're right I might as well take advantage of it 100%.

I have a feeling, given our insane spending and wastefull habits, that just having a car to drive, any car whether it has AC or not, is going to be a BIG DEAL sometime in the not too distant future. I think someday the Yaris will be seen to be a BIG car with a rather large and powerfull engine. |

As government regulation now stands, by 2016 the current Yaris will have average mileage for a US-sold car.
