Summer's Here, Where Can you Get the Cheapest Gas?

We're on a roll.

A day before the first official day of summer — when fuel costs typically spike — the price of gasoline got a little bit cheaper, marking five weeks of decline.

The national average cost for a gallon of regular unleaded fell another nickel since last week to $3.64 — that's 22 cents cheaper than a month ago, according to the California State Automobile Association website. It's still a ways up from $2.73, the price of a gallon a year ago.

California's fuel prices outpaced the national average, however. The state average: $3.90 per gallon of unleaded. Still, that's 4 cents less than a week ago. It's also 24 cents less than a month ago and 79 cents more than this time last year.

This week's average per-gallon cost on unleaded fuel in the East Bay's Oakland metro area is $3.89, a few cents down from last Monday and 26 cents down from a month ago.

You can find a better deal if you shop around, though.

The cheapest gas in San Ramon this week is $3.79 per gallon of unleaded – that's at Valero on Market Place and the Dougherty Valley Safeway, according to www.gasbuddy.com, which updates the prices daily. The most expensive gas in town as of Monday was for $4.09 at the Chevron on Fostoria Way and Camino Ramon.

It's cheaper in neighboring Danville, where you can find gas for $3.75 a gallon at the Arco on Boone Court right off of San Ramon Valley Boulevard.

In Alamo, the cheapest gas is at Rotten Robbie for $3.85 a galllon, on Danville Boulevard and Las Trampas Road.

The best deal on gas in Walnut Creek is found at Ideal Miles Plus at Ygnacio Valley Road and Civic Drive, where it's $3.84 a gallon.
