It's no fun driving around in ice and snow. It turns out,
all this cold air is also bad for gas mileage. Thicker air and freezing
temperatures actually force your car's engine to work harder.
So idling your engine to get the heater blowing warm air
before you start your morning commute isn't a good thing if you're trying to
save money on gasoline. Most cars these days just need 30-seconds to warm-up
the engine before it's safe to drive away. Some experts argue that leaving all of
our cars out idling on winter mornings sends millions
of tons of carbon dioxide into the atmosphere, too, and contributes
to climate change.
Your tire pressure is affected by the temperature change, as
well. For every 10° drop in the temperature, you lose about 1% of your tire
pressure. Sagging tires keep your car from running smoothly down the highway,
making your gas mileage suffer.
Here's an interesting note, too: Cold air is thicker so it
takes more effort to move your car through it. More effort equals more gasoline
that your engine needs. For every 10° drop in temperature, there's a 2%
increase in aerodynamic drag.
