The average price of a gallon of self-serve regular gasoline in the Inland Empire rose today to its highest amount since Sept. 15, 2015, increasing 1 cent to $3.235.
The average price in Riverside and San Bernardino counties has risen nine consecutive days, increasing 22.9 cents, including 2.3 cents on Tuesday, according to figures from the AAA and Oil Price Information Service.
The average price is 14.7 cents more than one week ago, 19.8 cents higher than one month ago and 40.3 cents greater than one year ago
A statewide 12-cent a gallon gasoline tax increase went into effect last Wednesday.
Aside from the tax increase, one reason for the sharp price increase is “an unexpectedly strong demand for gasoline in October linked to warmer weather across the U.S.,” Marie Montgomery of the Automobile Club of Southern California told City News Service.
A second factor is that many refineries that had put off scheduled maintenance due to supply concerns stemming from disruptions caused by Hurricane Harvey are now performing that maintenance, causing fears of inadequate supply, Montgomery said.
