Don't look for prices at the pump to get much cheaper in coming weeks.

After four months of declining gas prices, the cost of fuel is beginning to stabilize across the nation, industry analyst Trilby Lundberg said Sunday.

Since Aug. 11, when gas prices peaked at $3.03 a gallon nationwide, there has been a steady decline that has reached almost a dollar, Lundberg said.

The national average for self-serve regular was $2.18 on Nov. 3, according to Lundberg's latest survey of 7,000 gas stations across the country. That's 2 cents less than on Oct. 20, the date of the previous survey.

Mid-grade prices averaged $2.30 a gallon, while premium cost $2.40.

The lowest average price in the survey was in Tulsa, Okla., at $1.99 a gallon for regular.

The highest average price continues to be in Honolulu, at $2.77.

California prices fell more than the national average by about nine cents.

Among California cities surveyed, the highest average price for regular was $2.37 a gallon in San Francisco. The lowest was in Sacramento, at $2.24 a gallon.
