AUGUSTA — Maine’s average gasoline prices are continuing their downward slide, but they’re still not as low as they were a year ago.

MaineGasPrices.com says average retail gasoline prices in the state have fallen 0.8 cent per gallon in the past week, averaging $3.50 on Sunday. While that average is 23.2 cents per gallon lower than a month ago, it’s still 66.4 cents per gallon higher than on the same day one year ago.

The website says the national average has fallen 2.1 cents in the last week to $3.42.

Price analyst Patrick DeHaan says the volatility in oil prices isn’t surprising, and likely will continue as a fragile economy and some upbeat investors play the market. For motorists, he says that means a continued roller coaster ride at the gas pump.
