Plunging crude oil prices pushing at-the-pump costs lower

The streak goes on. Sacramento-area gas prices edged downward for the 13th consecutive week.

Analysts attributed it to low prices for crude oil – which on Tuesday dipped to less than $90 a barrel – and a stable supply of gasoline.

National price tracker GasBuddy.com, which surveys more than 700 regional gas outlets daily, said the average retail price Tuesday in the Sacramento region was $3.56 a gallon. That’s down from $3.59 one week ago. It’s nearly 20 cents lower than a month ago and 23 cents lower than this time last year.

Nationally, the average price of gas Tuesday was $3.27 a gallon – down 6 cents from a week ago, a drop of 17 cents from last month and 9 cents lower than a year ago.

“We’ve begun to see retail prices eroding at a much faster rate in the last few days across a good portion of the country,” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. “...Motorists should be seeing continued drops in gas prices across much of the United States in the week ahead as gas prices catch up to the recent decrease in crude oil prices.”
