AUGUSTA — Average retail gasoline prices in Maine are up slightly, but the price of home heating oil remains stable.

A price-monitoring website,, says average gasoline prices in Maine have risen 0.6 cent per gallon in the past week, to an average $2.74 per gallon on Sunday. The national average has also increased 0.6 cent per gallon in the last week to $2.75 per gallon.

Meanwhile, state energy officials say the statewide average cash price for No. 2 heating oil is $2.58 per gallon, unchanged for the last three weeks.

Energy Director John Kerry said today that heating oil prices have remained high during the recession and crude oil is trending upward, which will likely lead to higher petroleum prices this winter.
