Industry analyst Trilby Lundberg said today the hike mostly results from an agreement November 30 by major oil-producing countries to slash output.
Lundberg says the current price is 20 cents a gallon above what it was one year ago. But the 2016 average price is 31 cents below the 2015 average, and USD 1.21 a gallon below the 2014 average.
Gas in San Diego was the highest in the continental United States at USD 2.68 a gallon on average Friday. The low average was in El Paso, Texas, at USD 1.99 a gallon.
