Gasoline prices rose  again Friday and are now averaging more than $4 in six states and  Washington, D.C. Oil had its biggest gain in three weeks and natural gas  prices also rose.       
Retail gasoline prices were up a penny on Friday to a national  average of $3.831 per gallon, according to AAA, Wright Express and Oil  Price Information Service.
The average price for a gallon of regular is now above $4 in Alaska, California, Connecticut, Hawaii, Illinois and New York.
Gasoline  has jumped by almost 56 cents per gallon since Jan. 1 and is the  highest ever for this time of year. That’s costing drivers an extra  $11.20 to fill up a 20-gallon tank. Experts are forecasting that the  nationwide average could reach $4.25 by the end of April.
For now,  consumers aren’t seeing similar increases in other areas. The Labor  Department said Friday that excluding energy prices, inflation stayed  mild in February. Food prices were unchanged for the first time in 19  months.
Yet there are signs that high gas prices are weighing on  consumer confidence and the growth that fuels job creation. Economists  fear consumers could cut spending on other goods, from appliances to  furniture to electronics and vacations.
Gas prices are rising  primarily because of high oil prices. On Friday oil markets were still  reacting to reports a day earlier that the U.S. and the U.K. planned to  release some of their strategic crude reserves. Although the White House  denied the reports, independent analyst Andrew Lipow said traders were  left to worry that Western nations are preparing for a prolonged  standoff with Iran over its nuclear program.
 “What do they know that they’re not telling?” Lipow said.
Tensions  with Iran, and the threat to oil supplies in the Middle East, are a big  reason that oil has risen about 7 percent since Jan. 1 and almost 15  percent since October.
In New York trading, benchmark oil for  April delivery rose $1.95, or about 2 percent, to finish at $107.06, the  biggest gain since Feb. 24. Brent crude for May delivery rose $3.21, or  2.6 percent, to end at $125.81 per barrel on the ICE Futures exchange  in London.
Natural gas, which is trading at prices not seen since 2002, rose 4.7 cents to finish at $2.326 per 1,000 cubic feet.
Heating oil rose 5.94 cents to end at $3.2819 per gallon and gasoline futures gained 6.84 cents to finish at $3.3569 per gallon.
