SANTA MONICA, Calif. — The national average price of unleaded regular gasoline has been hovering between $3.50 and $4 for almost a year now and it's a pretty safe bet that the day of gas for $2.50 per gallon is long gone. In fact, many people worry about someday having to pay $5 per gallon, or more. As gasoline prices rise and fall, but never seem to fall very far before rising again, some people will be tempted to dump their current cars for more fuel-efficient models. Others will fall prey to the latest gas-saving gizmos and concoctions from the auto parts store.
There's a chance, though, that some who hurriedly decide to downsize will get burned. There's an even greater likelihood that those who spend money on devices and additives claiming to magically improve a vehicle's fuel economy will be dumping that cash down the drain.
Don't be one of them.
