Using your cell phone while pumping gas can trigger an explosion.

Is it really dangerous to use your wireless phone while your pumping gas? I mean everyone does it right? Or do they? This rumor has been around for some time now, but is it true? There are warning signs at the pump…

The Federal Communication Commission (FCC) investigated these “rumors” that “There Is No Evidence That These Reports Are True.” Now according to the wireless industry studies, sparks “could possibly ignite flammable materials,” but only in “very precise conditions.”

So we have it, the FCC concluded: “There is no documented incident where the use of a wireless phone was found to cause a fire or explosion at a gas station,” and “scientific testing, however, has not established a dangerous link between wireless phones and fuel vapors.”

You get more for your money when you fill your gas tank in the morning.

You’ve heard that when temperatures are cool, gasoline is denser, so you get more fuel per gallon pumped. Right?

Do we really get more for your money when you fill up in the morning.

According to Consumer Reports, “the temperature of the gasoline coming out of the nozzle changes very little, if at all, during any 24-hour period of time since it is stored in underground tanks.”

Inflate tires to the pressure shown on the tire's sidewall.

Ok, let’s get this straight. Why is this one in the list? What is the recommended pounds-per-square-inch (or P.S.I.) for my vehicle?

Well, the PSI noted on the sidewall of your tires is the maximum pressure the tire can safely hold. The automakers recommended pressure is usually found on a doorjamb sticker, on the fuel-filler door, or in the glove box which provides the best balance of braking, gas mileage, handling, and ride comfort. This is all presuming you are using factory wheels. Custom wheels may vary.

It’s estimated that if the tire pressure is down 10 PSI, “testing has shown that it can make a 1 mpg difference in fuel economy.”
