Pay less for gas

I've seen a few variations on this at different spots, but wanted to share a good list of simple ways to reduce the incredibly awful amount that we are paying for gas.

1. Check your tire pressure, monthly with a gauge when cold. Correct pressure is in owner's manual and on driver's side door jamb.
2. Don't idle. If you'll be idling for 30 seconds or more, better to turn off the car and restart.
3. Slow down. Dropping from 70 to 60 mph can increase mileage by as much as 18%.
4. Drive steadily.
5. Lighten up. The heavier the car, the more gas needed. Carrying extra junk in the trunk? Take a few moments to empty out.

These won't come close to making driving cheap, but every little bit helps!
