COLUMBUS, Ohio (WTVN) --Central Ohio gasoline prices went down some more in the past week.

According to, the average for a gallon of unleaded was selling at $3.38 Monday morning, 14 cents cheaper than a week ago.

AAA's Daily Fuel Gauge Report shows the Ohio average at $3.37, down 12 cents from the same time last week.

The national average, at $3.51, is down a nickel and is the lowest since March as it continues the decline it began a month ago. Senior Petroleum Analyst Patrick DeHaan says no states in the lower 48 feature average prices over $4 a gallon.

In addition, he says, a month ago, nearly 75% of gas stations were charging over $3.50 a gallon, while today we see just 38.2% of all stations over that level, "an impressive decline in price that GasBuddy alerted motorists to weeks ago," DeHaan said.
