As your speed increases, your aerodynamic drag increases in an exponential fashion. Driving 62 mph (100 km/h) vs. 75 mph (120 km/h) will reduce fuel consumption by about 15%.
By anticipating the traffic and applying slow steady acceleration and braking, fuel economy may increase by as much as 20%.
Keep tire air pressure at the level recommended by your vehicle manufacturer. A single tire under inflated by 2 PSI, increases fuel consumption by 1%.
When the air conditioner is on it puts extra load on the engine forcing more fuel to be used (by about 20%). The defrost position on most vehicles also uses the air conditioner.
Windows open, especially at highway speeds, increase drag and result in decreased fuel economy of up to 10%.
Proper maintenance avoids poor fuel economy related to dirty air filters, old spark plugs or low fluid levels.
Maintaining a constant speed over long distances often saves gas.
Remove the sand bags from your trunk in the spring and pack lightly for long trips.
If you anticipate being stopped for more than 1 minute, shut off the car. Restarting the car uses less fuel than letting it idle for this time.
When buying a new vehicle examine the vehicle’s rated fuel efficiency. Usually choosing a small vehicle with a manual transmission will provide you with great fuel economy.
In most regions, you will find the cheapest gas prices in the same areas. In major metro areas, this seems to be outlying suburbs. It is best to avoid affluent areas when looking for a cheap fill. Gas stations near major freeway exits can be more expensive than stations further away.
With gas prices reaching record levels, it’s more important than ever to keep tabs on your gas spending. One of the easiest ways to save money on gas is to shop around, by using this web site.
Some stations are always the price leaders in the area. Often times wholesale clubs, grocery stores or department stores with gas stations will sell gas close to cost or at a loss (loss leader), in order to get people into the stores where they may buy other, higher margin items. Some of these places require memberships. The cost of the membership must be factored into the price. Some of these stations also give you a credit for in store purchases when you fill up with gas. This can result in considerable indirect savings. Service stations, with an auto repair shop on site, often have more expensive gas.
One of the best ways to lower your fuel expenses is to carpool to work. You can reduce the inconvenience by sharing a ride with someone that works at the same company, and lives near your home. Many companies have a highin board, or Intranet web site where you may be able to find someone to carpool with.
Another great option is public transportation. Passes are usually available at discounted rates. Although you have to pay to use public transportation, is usually much less expensive than driving to work, and paying for parking (where applicable).
Some other options are walking, or riding bike to work. Both of these options have the added benefit of giving you exercise.
