Average retail gasoline prices in Minnesota have fallen 3 cents in the past week, averaging $3.32 per gallon Thursday, according to GasBuddy’s daily survey of 2,856 gas outlets in Minnesota. This compares with the national average that has decreased 5.8 cents per gallon in the last week to $3.43 per gallon, according to gasoline price website MinnesotaGasPrices.com.

Including the change in gas prices in Minnesota during the past week, prices Sunday were 52.8 cents per gallon lower compared to the same day one year ago and are 32.1 cents per gallon lower than a month ago. The national average has decreased 18.8 cents during the last month and stands 36.6 cents per gallon lower than this day one year ago.

“Gasoline prices continue to erode with twelve states that are seeing prices under $3 per gallon, and more states will join in on that over the next seven days” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. “While it’s generally good news that gasoline prices continue falling, many Americans don’t believe we’re likely to see national averages drop under $3 per gallom over the next year at the pump,” DeHaan said.

GasBuddy surveyed over 10,000 motorists with two-thirds of respondents saying that the national average will remain between $3 and $4 per gallon through 2014. Perhaps in a sign of positive sentiment, just 13 percent of respondents said they thought that prices nationally would exceed $4 per gallon, while 20 percent believed prices could go under $3per gallon.

GasBuddy operates MinnesotaGasPrices.com and over 250 similar websites that track gasoline prices at more than 140,000 gasoline stations in the United States and Canada.
