Gas Prices Skyrocket; How Are You Affected?

Average gas prices in Ross Valley have skyrocketed over the past month, jumping by more than 51 cents to $4.41 per gallon, according to a report released this week by AAA. That matches a trend across the Bay Area, AAA officials said.

Even the cheapest station in San Anselmo and Fairfax, the San Anselmo Beacon on Sir Francis Drake Boulevard, has gone up dramatically over the past month, hitting $4.30 this week. The current average price across the gas stations in Ross Valley of $4.35 is cents higher than the same period a year ago.

The increase in local gas prices outpaces the jump in average prices nationwide; AAA officials said that across the country, gas prices rose by 30 cents, to $3.81 per gallon, from February to March.

The region's average gas price is slightly higher than the state's, which is $4.36 per gallon.

AAA spokesman Matt Skryja said increased buying activity by investors in oil and gas futures and political tensions with Iran have pushed prices upward over the past month. He noted, however, that prices appear to have flattened on Wednesday as “concerns over a slowing economy in China and easing tensions with Iran helped pull down the price of oil.”

According to the AAA report, San Rafael and San Francisco are among the highest average gas prices for March at $4.43 per gallon of regular unleaded. Vallejo is among the lowest in the region at $4.31, according to AAA.

Skryja said seasonal fluctuations are typical, particularly in April, when summer fuel blends, which make sure that gasoline doesn't vaporize as temperatures rise but require more expensive additives to do so, are introduced. But drivers don’t normally see a spike in gas prices in March, he said.

While the average price for March in San Rafael, the closest metro area for which AAA regularly records gas price data, was $4.43 per gallon, a 48-cent jump from the same period a year ago and up from $3.09 per gallon in March 2010.

The high prices come despite dropping demand for oil -- a U.S. Department of Energy report released last week found that the nation was using 8.36 million barrels a day, the lowest rate since March 2001.

To get the best mileage possible, AAA recommends keeping tires at the proper pressure suggested by the vehicle manufacturer, performing routine maintenance and making sure fluids are clean and belts and hoses are in good repair. The organization also recommends avoiding sudden stops and starts, planning errands and lightening your load also help conserve gasoline.
