The cost of gas has been well-above $3 for some time now, but now news sources across the country are reporting prices have gone past $4 per gallon. AAA's Daily Fuel Gauge Report indicates that the national average is about $3.61 for regular unleaded gas, but states like California, Washington, Oregon, New York, Maine, West Virginia and Connecticut are seeing an average of $4.27.

ABC News affiliate KGO-TV reports that by noon on Wednesday, a gas station near the San Francisco Airport was selling regular fuel for $4.59 per gallon. Things are ever worse for Florida drivers, where gas prices have reached nearly $6 per gallon in some areas. Drivers are filling up for $5.79 in Orlando, according to CBS Tampa. The rest of the state is closer to the national average, but Florida motorists are still paying about 12 cents more than average.

"Prices over in Disney World area are much higher than any other place in Florida," AAA spokeswoman Jessica Brady told the news source. "It doesn't look like we will have relief at the pump anytime soon. I do think we will see prices surpass $4 a gallon. I think we will see that closer to springtime."

Drivers can take steps to improve the fuel economy of their current vehicles. Shutting off vehicles while they are idling is a wise move, as the U.S. Department of Energy reports idling can use between a quarter and a half gallon of gas per hour. Observing speed limits will reduce fuel consumption as well. Mileage typically decreases significantly at speeds above 60 miles per hour.

Getting regular maintenance and oil changes improves the engine's efficiency as well. Drivers can take their cars to New Jersey State Auto Auction's Total Car Care center, located in Jersey City and open to the public, to get tuneups, oil changes and make sure their vehicles are running smoothly.
