Fall has officially arrived. It’s marked as much with falling gas prices as it is with falling leaves.

The average price of gasoline dropped 2 cents last week, following the national lead. The national average price for regular unleaded gasoline has dropped for nine consecutive days, reaching a national average of $2.24 per gallon. The state average is now $2.09 a gallon, according to AAA Kansas.

Dropping demand, a changeover to winter blend and uncertainty over Organization of the Petroleum Exporting Countries future plans are dropping the price of gas.

"October is a time we all expect gas prices to decline," said Gregg Laskoski, a senior petroleum analyst for GasBuddy.com. "Looking at the change in the US average price for Octobers from 2015 to 2012, it’s dropped from Oct. 1 to Oct. 31 by 12, 34, 11 and 26 cents respectively.

"That’s an average decrease of 20 cents per gallon during the last four Octobers."

While cost declines are expected in the month, things are a little different this year.

"This month has proven to be an exception with the national average still a few cents higher than where it was on Oct. 1 at $2.22," Laskoski said. "While the price increase of crude oil has stalled the expected price decrease for retail gasoline, problems at major refineries in Indiana, Texas, Louisiana and California have adversely impacted supply as well.

"The most recent EIA report shows US refinery output at just 85.5 percent, the lowest level since Jan. 22, 2015."
