Thanksgiving gas prices lowest since 2010

As families take to the road for the Thanksgiving holiday, they have something to celebrate: gasoline prices that are the lowest for the week since 2010, according to Energy Department price watchers.

"Despite this week's increase in regular-grade gasoline prices to an average of $3.29 per gallon, the price of gasoline is lower than three months ago, 14 cents less than a year ago," the Energy Information Administration reports.

Lower prices should be critical to the 38 million that AAA predicts will travel by car through Sunday.

While the price of regular-grade gas has been holding relatively steady, AAA Daily Fuel Gauge Report says midgrade gas Wednesday averages $3.453 a gallon and premium is $3.629 a gallon. Diesel fuel is going to for an average $3.843 a gallon.
