LOS ANGELES — While the national average gasoline price is around $2.33 per gallon, Los Angeles drivers are paying more than $1 more. But a special “Tank Takeover” promotion this week from GasBuddy will roll prices back to 2009 levels.

GasBuddy, the crowd-sourced fuel-price intelligence provider, is partnering with G&M Oil Co. Inc. to take over some of its Los Angeles and Orange County gas stations and offer a special, limited-time gasoline price and in-store deals.

G&M Oil, Huntington Beach, Calif., has more than 140 G&M Food Mart and Extra Mile Chevron-branded stores throughout Southern California.

The promotion will run from Sept. 16-18, 2015, and offer gas prices “for a fraction” of the Los Angeles average, according to GasBuddy. The discounted price will apply only to vehicle fillups of gasoline. It will not be applicable to container fillups or diesel purchases. G&M Oil customers who download the retailer’s and GasBuddy’s mobile apps will also get deals such as free refreshments and savings on convenience-store items.

“This year Southern California has been plagued with sudden and huge price spikes,” said Allison Mac, director of public relations for GasBuddy, Gaithersburg, Md. “Our mission has always been to help people save money at the pump. This week we are taking it a step further and literally providing the cheapest gas possible to a city that could use the relief.”

G&M Oil was founded in 1969, and today owns and operates more than 140 c-stores and gas stations in San Diego, Riverside, San Bernardino, Orange, Los Angeles and Ventura counties.

GasBuddy’s fuel-price app and website feature real-time fuel prices at more than 130,000 stations in the United States and Canada.
