Average retail gasoline prices in Minnesota have fallen 12 cents in the past week, averaging $3.37 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 4.5 cents per gallon in the last week to $3.49 per gallon, according to gasoline price website MinnesotaGasPrices.com.

Including the change in gas prices in Minnesota during the past week, prices Sunday were 48.9 cents per gallon lower compared to the same day one year ago and are 11.2 cents per gallon lower than a month ago. The national average has decreased 7.3 cents during the last month and stands 32.1 cents per gallon lower than this day one year ago.

“Gasoline prices continue to move lower nationally as we’ve now officially moved into fall,” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. “Looking forward, we’re likely to see additional relief at pumps in the months ahead, and it’s quite possible that by the time we’re observing Thanksgiving that gasoline prices will be twenty or more cents per gallon lower. Californian motorists will see among the larger decreases in the week ahead as refinery issues have become barely visible in the rear view, which has led to a dramatic downward shift in wholesale gasoline prices,” DeHaan said.

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.
