Oil, gasoline, Natural gas, Price august 19 2011 ; Oil ended the day below $83 a barrel on Friday, finishing down about 4 percent for the week. That could spell more relief at the gas pump.



The national average for retail gasoline is $3.59 a gallon, according to AAA, Wright Express and Oil Price Information Service. That's down 10 percent from this year's high of $3.98 on May 5. Gas could be around $3.25 a gallon by Labor Day and may drop as low as $3.15 by the end of the year, according to Fred Rozell, OPIS retail pricing director.



While gas may be headed lower, it's still taking a big piece out of household income. The median U.S. household income before taxes is almost $50,000 a year. In July families spent about $374 a month on gasoline, or around 9 percent of household income, according to Rozell. For the year, monthly gas expenses average about 8.4 percent, compared with 6.7 percent in 2010.

PFGBest analyst Phil Flynn thinks traders may have overreacted after oil fell nearly 6 percent Thursday on a batch of negative economic news. He said that traders will remain guarded until there is more clarity about where the economy may be headed.



Crude got some support Friday from a weaker dollar, which hit a new post-World War II low against the Japanese yen. Oil and other commodities are priced in dollars, so a weaker dollar makes them cheaper for traders who use other currencies. Oil lost some ground by the end of the day as the dollar got a little stronger.
