The Automobile Club of Southern California has announced a significant rise in gas prices across most areas of Southern California, marking the second such increase this year during the week of August 28.
According to the Automobile Club of Southern California, on August 28, 2025, the statewide average for self-serve regular gasoline was $4.59 per gallon. This figure represents an increase of 10 cents from the previous week and is three cents below last year’s price. The national average stood at $3.21, which is eight cents higher than the prior week and 15 cents lower than a year ago. Local averages were reported as $4.61 in Los Angeles-Long Beach, $4.67 in San Diego, $4.58 on the Central Coast, $4.46 in Riverside, and $4.52 in Bakersfield, with weekly changes ranging from seven to 15 cents and year-over-year differences from seven cents lower to four cents higher.
As of September 2, 2025, Shupe said that Riverside gas prices averaged $4.48 for regular gasoline, with midgrade at $4.70, premium at $4.90, and diesel at $5.01. These figures represent a slight increase from a week ago and remain roughly unchanged from a year earlier. In San Bernardino, averages were recorded as $4.53 for regular gasoline, $4.72 for midgrade, $4.93 for premium, and $5.03 for diesel—showing modest rises from last week while remaining close to last year’s prices.
“Most of the recent price increases at the pump happened last weekend after a spike in Los Angeles wholesale gasoline prices due to some unplanned refinery maintenance,” said Auto Club spokesperson Doug Shupe via a press release by Oil Price Information Service.
