AUGUSTA, Maine (AP) — Maine gas prices have jumped another eight cents in the past week to an average of $3.77 per gallon.

Price-monitoring website MaineGasPrices.com reports Monday that while the jump in Maine is lower than the national average, the retail price of gasoline in the state remains about 13 cents above the national level.

Prices are now more than 38 cents per gallon higher than the same day a year ago and 24 cents per gallon higher than a month ago.

The national average has increased almost 27 cents per gallon during the last month and is 30 cents per gallon higher than the same day a year ago.

A company analyst says crude oil speculation and Middle East volatility are driving up prices.
