SLO County has priciest gas in California again, survey shows

San Luis Obispo County once again has the most expensive gasoline in California, according to a survey by the AAA and Oil Price Information Service.

The survey found that the average price for regular unleaded in the San Luis Obispo-Atascadero-Paso Robles area is $4.009 per gallon.

A year ago, the local average price of regular gas was $3.065 per gallon, according to the AAA Fuel Gauge report.

This week’s local gas price is fractionally more expensive than San Francisco’s $3.998 per gallon. San Francisco typically has the most expensive gas in California.

The cheapest gas reported in the 25 California markets surveyed was in Yuba City and Yolo County near Sacramento, where a gallon of regular cost $3.878, AAA reported. All prices are as of Tuesday.

In a different report, done by the Lundberg Survey, the average U.S. price of a gallon of gasoline was up nearly six cents over the past two weeks.

The Lundberg Survey put the price of a gallon of regular at an average of $3.67 nationally.

Of the cities surveyed by Lundberg, Tucson, Ariz., had the nation’s lowest average price for gas at $3.32. Chicago had the highest at $4.02.

In California, the lowest average price was $3.85 in Fresno, according to the Lundberg Survey. San Diegans paid the highest price at $3.95. The average statewide was $3.92, up about 20 cents.

The reports can show different results because they each survey different gas stations.

National experts said the threat of hurricanes in the Gulf of Mexico has helped drive the gas price up nationally. Once the season for hurricanes starts winding down, and the summer driving period comes to a close, experts think prices will start dropping.
