Welcome back to the grind and the third monthly thread and the last one of 2018 The national average gas price is massively down 30.8¢ since last month at $2.493 - this time last year it was up to $2.490 so it's actually marginally cheaper -0.4¢. Diesel is only down 11¢ at $3.172. It's still 33.2¢ more expensive than this time last year and at a 27.2% premium to regular! E85 is down to $2.178 - a year ago it was $2.065. Yesterday, Columbus gas prices dropped below $2.00. AAA and Gas Buddy are reporting gas prices are at their lowest in metro Columbus since February. "I was over here in this neck of the woods and I get updates on my phone about the lowest gas prices, well it said 'Get Go' had gas for $1.99 and I didn't believe it. So I had to come over here and see for myself. I thought it was a mis-glitch on the phone. I got over here and a $1.99, couldn't be any happier," said Josh Arledge. AAA says there are a couple of reason for the low prices. Crude oil prices have dropped 20 percent since the beginning of November. That's because we have a global supply surplus of crude oil. Second, we are at the time of year when we typically see lower gas prices. That's because refiners have finished up their fall maintenance and are running at nearly full strength. Also, they are making the cheaper winter blend of gasoline. Third, demand is lower because we are past the busy summer driving season. With abundant supply of crude oil and gasoline and lower demand, we see the prices drop.
