Mayra Orozco of Santa Rosa keeps an eye on gasoline prices as she drives around town.
Especially at this time of year, when her husband's income from odd jobs, such as painting, drops off.
On Wednesday, Orozco found what she was looking for at the Roseland Gas Mart -- across the street from her daughter's school, Roseland Elementary -- where regular gas was $3.80 a gallon.
"It's a good thing. The cheaper the better," Orozco said after pumping $20 worth into her shiny gray Ford 150 pickup.
The average price for regular gas fell to $3.93 on Wednesday in Santa Rosa, down 16 cents a gallon from a week ago and 71 cents less than a month ago, according to the AAA Fuel Gauge Report, which uses an average of the three preceding days.
A year ago, gas averaged $3.85 in Santa Rosa, the report said.
The website GasBuddy.com, which posts prices reported by motorists, listed 14 Santa Rosa stations selling gas for $3.80 or less on Wednesday.
Orozco said she appreciated the sudden drop in prices, which hit a record $4.65 here on Oct. 9. A few weeks ago she pulled off the freeway in Novato, low on gas, and paid $4.60 a gallon.
"That one hurt," Orozco said.
Declining crude oil prices attributed to slower economic growth, combined with the seasonal shift to cheaper winter-grade gasoline, pushed down prices at the pump, the U.S. Energy Information Administration said Wednesday.
