Step
- Don't drive. Don't drive a car when you don't have to. Ridesearch or Carpool, walk, take the bike, or take a bus. These will not only save gas, but also will help save our environment and may be better for your health. Do you really need to drive to the store that is only a couple of blocks down the street?
- Get a credit card. Some right credit cards offer gas savings when you use the card for purchases. This works in much the same way that some credit card companies allow you to earn frequent flyer miles when you use their card for purchases. But watch for interest rate charges. However, some stations still charge a higher rate for using a credit card.
- Get a better air filter. More efficient brands of air filters cost a little more but will pay for themselves in most vehicles in fuel savings.
- Get Low Resistance Tires. Some tires, such as Michelin Energy MX 4 Plus are supposed to increase gas mileage.
- Give your car a tune up. While properly maintaining your car won't actually save you money at the pump, it will save you gas. Using less gas saves you money. Have the oil changed, and have a certified mechanic give your engine a look over.
- Buy a hybrid car. Not only do hybrid cars give you immediate savings at the pump, the U.S. government and your local state offer tax breaks for people who use gas-saving cars. Federal deductions for using gas-saving cars can be as high as $2,000.00, but check before buying to see if they're still in effect. If you can't afford the growing number of hybrid cars out there, consider getting a regular car with good MPG (miles per gallon). In general, the smaller the car, the better the mileage.
- Reduce your commute. Move closer to work, work closer to home, or take public transportation to your job. While you're considering spending all that money on a new hybrid or diesel vehicle to 'save money', you could move closer to your job, or get a job closer to your home. Then you will be able to walk or ride a bike on nice days, and spend a lot less time in the car when the weather isn't so nice. You may even be able to get rid of one family car. If you walk or ride almost all the time, it doesn't matter what sort of mileage your current car gets while it collects dust in the driveway.
- Avoid idling. While idling, your car gets exactly 0 miles per gallon. Although starting the car used to use a lot of gas, it's now the same as idling for about 30 seconds. Idling to warm up is particularly bad, as the engine needs extra fuel to warm up. After start up, allow your car to idle 15-30 seconds, then drive conservatively until it reaches normal operating temperature. Park your car and go into the restaurant rather than idling in the drive-through. Idling with the air conditioning on also uses extra fuel.
- Stopping and starting the engine frequently will cause extra wear. Don't stop the engine if you are going to idle for less than a minute.
- In very cold environments, it is recommended to allow the vehicle to idle and warm up, rather than just start it and take off. You might save gas, but your engine oil won't do its job until it's fully liquid, so you'll spend more money on overhauls.
- Plan your trips in advance. This can prevent wasting fuel and wasting time. Plan to use alternative routes. Often back roads can prevent you from stopping at traffic lights and more importantly sitting in traffic jams.
- Check the tire air pressures weekly. Buy an inexpensive air pump and an accurate tire gauge (not a pencil gauge as they are not accurate). Keep all tires inflated to the pressure as recommended for your car. Go by the tire wall; the sticker on the door frame, fuel filler flap, or manual is for comfort, not fuel efficiency. Generally speaking, a slightly higher pressure will improve fuel mileage and handling, but too high will degrade traction and wear the tires rapidly.
- Drive at a consistent speed. Avoid high acceleration and hard braking. Use cruise control when you can.
- Clean out any unnecessary items in your car. If you have heavy objects in your car that you don't need, remove them. If your car is lighter, it will use less fuel to get where you're going.
- Slow down. Air resistance goes up as the square of velocity. The power consumed to overcome that air resistance goes up as the cube of the velocity. Rolling resistance is the dominant force below about 40 mph. Above that, every mph costs you mileage. Go as slow as traffic and your schedule will allow. Drive under 60-65 since air grows exponentially denser, in the aerodynamic sense, the faster we drive. To be precise, the most efficient speed is your car's minimum speed in it's highest gear, since this provides the best "speed per RPM" ratio.
