The slowing world economy has brought a little good news for Americans in the form of falling gas prices.

Experts explain a weaker economy means less demand for oil. So far crude has fallen to $83 a barrel, and the national average for a gallon of gas is down to approximately $3.59.

Analysts say they expect gas prices to keep falling.

"An impressive decline in average gasoline prices will now be extended as the West Coast begins to see lower prices in the days ahead," said Patrick DeHaan, senior petroleum analyst from GasBuddy.com. "Motorists will continue to see prices sliding east of the Rockies."

Falling prices mean Americans will have more money to spend on other items.
