How long ago was the last time you checked your tires air pressure? Three months? Six months? Longer? With today’s high gas prices, that inefficiency can add up to significant money. At $3 a gallon for gas, a 25 mpg vehicle with neglected tire pressure will require an extra $60 of gas each year compared to a car with properly maintaned tires. The bottom lins is you have to start with a good tire gauge to maintain that pressure. Most digital gauges cost between $10 and $40, depending on the models’ specific features. Like a backlit screen, LED flashlight, and/or programmable memories that retain your car’s recommended front and rear tire pressure.

Here’s how to improve your car’s fuel economy:

Not everyone is in the market for a new vehicle. But that shouldn’t stop you from improving the fuel economy of the car or truck in your own driveway. Below are a few standard maintenance tips, and the precentage improvement they can house on your vehicle’s mpg.

• Replacing a dirty air filter-up to 10 precent.
• Getting an engine tuneup-average of 4 precent.
• Keeping tires inflated to the proper pressure-up to 3 precent.
• Using the recommended motor oil grade- up to 2 precent.
• Seek out low-resistance tires-up to 6 precent.

How to calculate your fuel economy:

1. Fill up your tank. But don’t top off-the extra gas more than likely will get sucked back into the station’s tanks anyway.Even if it doesn’t, the backfire vapors contribute to air pollution.

2. Reset your trip meter to zero. Now you’re on your own vehicles fuel economy clock.

3. Fill your tank when the time comes. In warmer months, you iwll get more gas for your money in the early morning or late evening, when the temperatures are cooler and gas is densest. Cooler conditions also mean less evaporative emissions from pumping gas, smog forms more easily when it’s hottest outside. In winter months, it’s a good idea to keep your tank at least half full for safety and to prevent freezing.

4. Write down the number of gallons it took to fill your tank and the number of miles on your trip meter. A receipt is an easy place to write these down; most already include the number of gallons you bought. Reset the trip meter before you restart the car.

5. Divide the trip miles by the gallons of gas. Bingo, that’s your fuel economy. For example: 293.1 miles divided by 8.374 gallons= 35 mpg

6. Keep a small notebook in you car or make a simple spreadsheet on your computer to track the numbers over time. There you could also records basic notes on mpg influences such as speed, tire pressure, driving conditions and use of air conditioning. If you see a dramatic drop from one tank to the next and don’t have an obvious explanation, your vehicle might need some maintenance. ( Source: Car and Driver 2007)

*Natural and Sustainable Living Tip: Keep your shades down in the summer and up in the winter to help conserve energy. If you have thick shades leave them down in the winter to help hold in the heat if your windows are drafty. To help conserve even more energy, you might consider replacing your windows with Energy Star approved ones.
