Inching up slightly, motorists saw average gasoline prices in Modesto rise by 1.1 cents per gallon in the last week, averaging $4.32/gallon as of Sept. 15.

That’s according to GasBuddy’s survey of 201 stations in Modesto, which show prices locally are 2.3 cents per gallon higher than a month ago and 36.7 cents per gallon lower than a year ago.

GasBuddy price reports indicate the cheapest station in Modesto was priced at $3.93/gallon while the most expensive was $5.01, a difference of $1.08/gallon. The lowest price in the state on Sept. 15 was $3.59 while the highest was $8.39, a difference of $4.80/gallon.

The national average price of gasoline has fallen 3.6 cents per gallon in the last week, averaging $3.12/gallon. The national average is down 1.8 cents per gallon from a month ago and stands 2.8 cents per gallon lower than a year ago, according to GasBuddy data compiled from more than 11 million weekly price reports covering over 150,000 gas stations across the country.

Neighboring areas and their current gas prices include: Stockton - $4.43/gallon, down 0.8 cents from last week’s $4.44; Oakland - $4.61, unchanged from last week; and San Jose - $4.53, down 2.8 cents from $4.56/gallon.

“While gas prices fell in more states than they rose last week, the West Coast continues to face challenges, with Oregon and Washington seeing some of the largest increases due to regional infrastructure issues,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The good news is that the transition to cheaper winter gasoline begins this week across most of the nation, and with improvements underway in the West Coast market, I expect that average gas prices will continue to decline in the weeks ahead in most states – assuming hurricane season remains quiet.”

Historical gasoline prices in Modesto and the national average going back 10 years show the highest price in Modesto on Sept. 1 was $5.28 in 2022 and the highest U.S. average was $3.85 in 2023.
