The price of gasoline took the long way around in 2013, ending the year just a few cents from its starting point, at least for the average national price and that of California and Massachusetts.
Predictably, the average weekly price of a gallon of regular gas in California stayed well above that of the U.S. average. California's average peaked in winter, hitting its weekly high for the year, $4.21, the week of Feb. 25. Its low for the year came the week of Nov. 25, at $3.55.
The U.S. average topped out at $3.78 a gallon on Feb. 25, and its low, $3.19, was reached on the week of Nov. 11.
