Gas Prices Soaring — Find the Cheapest in Rosemont

Across California, residents awoke Friday to find that gas prices had increased significantly overnight by as much as 20 cents. The average price of regular gas across the state had risen to $4.49 a gallon—the highest in the nation—and by Saturday evening had hit $4.65. That's compared with a California average of $4.18 on Monday, Oct. 1.

The current Sacramento-area average is slightly lower, at $4.53 a gallon. The cheapest gas in the Rosemont area Saturday was $4.53 at the Park N Gas at 8329 Folsom Blvd, according to GasBuddy.com. The highest price for gas was at the Chevron at 8099 Folsom Blvd, where a gallon of regular is $4.69.

The sharp rise has been attributed to decreased supply coming out of California's refineries, including the Chevron refinery in Richmond.

This time ten years ago, in 2002, the average price for gas in California was $1.55 a gallon, according to EnergyAlmanac.ca.gov. Last year, it was $3.82 a gallon.
