Retail gasoline prices continued to fall nationally and in California over the last week, the Energy Department said.
The U.S. average price for a gallon of regular gasoline fell 4 cents to $3.830, according to the Energy Department’s weekly survey that was released Monday. The U.S. average hit its peak for the year of $3.941 a gallon on April 2 and has fallen for four straight weeks. A year earlier, U.S. drivers spent 5.1 cents more for a gallon of gas.
In California, the average cost for a gallon of regular gasoline fell 1.7 cents to $4.186. California prices have fallen for seven straight weeks since reaching their high for the year of $4.376 on March 12. The current California average is 7.1 cents a gallon below the year-earlier price.
Gasoline prices have peaked before mid-May just once in the last 20 years and it hasn’t happened since 1998, according to Energy Department statistics, but one expert said 2012 has been an unusual year.
