NORTHERN CALIFORNIA – With falling gas prices, many Californians are on a roll and hitting the road for the remaining summer travel season.

Tuesday's average price in the Golden State was $3.91, representing a $0.23 decrease from a month ago, according to the AAA Northern California monthly gas survey.

Northern California’s average price for a gallon of regular unleaded gasoline is $3.93 – that’s $0.18 cents less than last month’s AAA reported price on July 8.

The highest recorded price ever registered in the state of California was in October of 2012, at $4.67 a gallon for unleaded regular.

The least expensive average price in Northern California can be found in Marysville, where regular unleaded gasoline is $3.72 per gallon.

Of all the metro areas tracked by AAA in Northern California, Eureka has the highest price at $4.24 per gallon of unleaded regular.

Hawaii has the highest average price, $4.32. California and Oregon are tied for highest average price, $3.91 in the contiguous states. South Carolina enjoys the lowest average price, $3.18.     

“As we approach the end of summer travel, gas prices continue their downward trend,” said Cynthia Harris, AAA Northern California spokesperson. “With ample supplies nationwide, and with no immediate threat to the distribution of oil, Californians should continue to enjoy relatively lower prices at the pump.”         

The national average price for regular unleaded gasoline has continued its downward trend despite high-profile conflicts in overseas oil producing countries and declining domestic refinery production.

Tuesday's price was $3.48 per gallon, which is $0.02 less than one week ago,$0.14 less than one month ago and $0.07 – less than the same date last year.

Despite the geopolitical headlines around the globe, oil prices continue to trade near multi-month lows.

The price of West Texas Intermediate (WTI) settled $0.43 – higher at $98.08 per barrel at the close of formal trading Tuesday, which is slightly lower than the price to begin last week and equal to the lowest settlement to begin a week since the start of February.

To get the best mileage possible, AAA recommends keeping tires at the recommended pressure suggested by the vehicle manufacturer, performing routine maintenance and making sure fluids are clean and belts and hoses are in good repair.

The way you drive can also impact fuel economy. Smooth driving to avoid sudden stops and starts, combining trips and lightening a vehicle’s load also help to conserve gasoline.
