After nine weeks of sky-high prices at the pump, gasoline prices leveled off this week as more supply entered the market and consumer demand flattened, according to the latest Automobile Club of Southern California weekend gas watch.

The average price of self-serve regular gasoline in the Los Angeles Long Beach area is $3.401, which is three-tenths of a cent higher than last week, 43 cents higher than last month and 90 cents higher than last year. The average price of diesel gasoline reached $3.434, off the record high of $3.461 reached on May 6. The Auto Club survey monitors the average price of gasoline each Friday.

“Nationally, gasoline refineries are producing at higher levels and consumer demand for gas is almost flat compared to last year,” said spokesperson Carol Thorp. “That’s removed a lot of the upward pressure on Southern California gas prices.”

If prices may remain near their current levels for a couple of weeks, it may indicate that the regional market has reached a peak, she said.

In the Inland Empire, the average price is $3.440, up one-tenth of a cent from last week, 43 cents above last month and 94 cents higher than last year. In San Diego, the price is $3.437, only two-tenths of a cent above last week’s price, 45 cents above last month and 94 cents above last year. On the Central Coast, the average price is $3.486, up one cent from last week, 42 cents above than last month and 86 cents higher than last year.
