After five weeks of gas price increases related to oil surging to record highs, prices in Los Angeles stayed constant while other areas of Southern California saw price dips, a sign the per-gallon cost of regular gasoline has crested, said the Automobile Club of Southern California.

The average price for regular self-serve unleaded gasoline in the Los Angeles-Long Beach area was frozen in place on Friday, coming in at the same $2.579 as one week ago. The price was $2.457 per gallon one month ago and $2.170 one year prior.

“For a good part of the summer, oil and gas markets have been whi-sawed, first by fears that there would be oil shortages this winter and then by two hurricanes,” said Auto Club spokeswoman Carol Thorp. “However, there is plenty of oil and gas to meet demand that is lower than expected. Motorists can expect to see slowly declining gasoline prices for the next couple of weeks, at least.”

The Riverside San Bernardino under-priced the Orange County area, which had the lowest average price in Southern California for four weeks in a row. The inland area dipped 1.3 cents to $2.555. The Santa Barbara-Santa Maria-Lompoc area had the highest gas price, falling one-tenth of a cent to $2.678.

The Weekend Gas Watch monitors the average price of gasoline as of 12:01 a.m. each Friday.
