MYTH: The number listed on the sidewall of your tire is the recommended tire pressure.

False:
In most cases, this is actually the maximum pressure allowed for that tire. The recommended amount of pressure is usually listed on the inside door panel – check your owner’s manual to be sure.

SAVE: The government estimates that the average driver’s tires are underinflated by 26 percent. Generally, underinflated treads lower gas mileage about a half percent for each pound lacking when the pressure of all four tires is added up. An average driver with underinflated tires could add $79 a year to his or her fuel bill – or more than $1,027 in the lifetime of the vehicle. You could also save nearly half a barrel of crude oil per year by keeping your tires inflated to the manufacturer’s recommended level. Per the EPA, one barrel of crude oil equals 42 gallons of gasoline.

MYTH: Buy gas in the morning and you’ll save money.

False: The old adage was to fill up in the morning when gas was coolest and most dense because gas is sold by volume and you would get more gas for your buck.

But gas is sold in underground, nonmetallic tanks that typically hold about 10,000 gallons, and it will take a lot of sunlight to raise the temperature even a degree. (However, pumping your gas when it’s cooler does mean less release of vapors, which is better for the environment.)

SAVE:
Do your research before buying. Ford’s SIRIUS Travel Link™ sorts gas stations by price on the navigation screen, but Web sites like MSNAutos.com can also help drivers navigate to bargains. In our quick research, we found two gas stations in New York City – less than a mile apart – with 30 cents per gallon price difference. If you know before you go and fill up for less every time, it could result in $227 in your pocket annually, or $2,951 saved over the lifetime of your car.

All totaled, by implementing small changes, drivers could save up to $538 a year or $6,610 in the lifetime of their vehicle. In today’s economy, every penny counts. That’s why it’s important to get the facts.
