Turn off the Ignition
While switching your vehicle on and off constantly is not advisable, there are some times when doing so will help to save fuel. Any time that you expect to be idle for more than three to four minutes, such as when waiting for a friend or a train, switch off the ignition. Even switching off the vehicle for this small amount of time is useful since it may occur multiple times per day. Other times to consider turning off the motor are when waiting in line at fast food restaurants or outside bank tellers.
Drive at the Proper Speed
Driving at a steady, constant speed uses less gasoline than constantly speeding up and slowing down. If you are on a highway or rural road, setting the cruise control will help you get better gas mileage by maintaining the speed you set it to. According to Bankrate.com, driving at 55 MPH instead of 65 MPH uses 2 gallons less per mile driven. It's not a coincidence that may federal speed limits were originally set to 55.
Don’t Overuse the Brakes
Overusing the brakes is typically a result of not driving at a proper speed. However, be aware that every time you step on the brakes the car uses extra fuel to speed back up. If you constantly speed up to the car in front of you and then have to brake, not only do you not get to your location faster, but it costs you more to do so because you use more fuel.
Don’t Warm up Vehicles on Cold Mornings
Modern cars do not require a warming up period like older models did. In fact, it takes only 30 to 60 seconds for your car to come to the proper operating temperatures. While you may like warming up your vehicle because the heater makes the cabin temperature warmer, you are wasting fuel by doing so. Instead, put on a coat and gloves, and wait for your vehicle to warm up naturally as you drive it, which occurs faster once it starts moving.
Roll up the Windows During Warm Temperatures
While having the wind blowing in your hair may feel nice, you won’t be happy with the higher fuel costs it causes. When windows are rolled down, it increases the aerodynamic drag, which causes more fuel to be used. In fact, fuel consumption may be increased up to 10 to 20 percent on highways when windows are rolled down.
