San Luis Obispo County's average gas price has fallen 7 cents in the last week to $4.68 a gallon, the AAA reported Tuesday.
Still, that puts the price back at what had been the previous record before the rapid run-up in the past few two week took it to $4.75 per gallon.
SLO County continues to have the most expensive gas in California, the AAA Daily Fuel Gauge Report shows. Second is San Francisco, at $4.66. The Los Angeles-Long Beach market was third, at $4.63.
A year ago a gallon of regular unleaded gas cost $3.92 in San Luis Obispo County, the AAA said.
Never miss a local story.
Some analysts have said the skyrocketing price increase resulted from problems at some refineries in the state and a shortage of fuel approved for use, given California's air-quality standards. In response to the price increases, Gov. Jerry Brown authorized refiners to start making the winter-blend gas three weeks earlier than normal as a way to increase supply.
SLO County has more expensive gas than other parts of California due to the cost to transport fuel to the Central Coast, as well as higher lease and rental costs that station owners have for their properties.
