Per-gallon area gas price average rises 6 cents

Average retail gasoline prices in the Nashville area rose 6 cents during the past week, averaging $3.48 per gallon as of Sunday, according to gasoline price website

This compares with the national average of $3.67, a rise of 5.4 cents.

Nashville prices yesterday were 3 cents per gallon lower than they were on the same day one year ago and 32.8 cents per gallon higher than they were four weeks ago. The national average has increased 24.8 cents per gallon during the last four weeks and stands 5.7 cents per gallon lower than on this day one year ago.

"The national average has spiked 25-cents per gallon just in the last month, thanks to an onslaught of refinery problems mainly in the Great Lakes and California," Senior Petroleum Analyst Patrick DeHaan said in a release. "While these situations are temporary in nature, it goes to show this nation’s dependence on domestic refineries. While oil prices have gained in recent days, there is some light at the end of the tunnel for motorists. Driving season will be over in less than a month and, soon thereafter, the EPA also relaxes gasoline mandates, meaning cheaper winter fuel."
