When I was a college student, this was my primary concern. I asked this question of many people, and out of the various advice I received, I found these to work the best:
- Have a light foot on the gas pedal. Don’t feel pressured to accelerate fast, because it’s not a race. Sure, some hotheads may get irritated with you, just move out of their way. They aren’t paying your gas bills.
– Change your routes, so you make as many right turns as possible, to keep your car moving. Red lights are very bad for gas.
– Take as many freeways as possible. Freeways use less gas.
– Understand that the most gas is used when you are idle, and when you accelerate. When your car is at a steady speed, less gas is used to keep it there.
I wish I still obeyed these rules, because I used to be able to use a full tank of gas for three weeks [Toyota Camry]. Nowadays I take the luxury of racing random people at stoplights. x.x
Of course, walking and biking would offer the most satisfaction.
