Naturally gas prices during the winter go down because the demand for filling up the tank and driving also goes down.

Peter Krueger, State Executive, Nevada Petroleum Marketers Convivence Store Association says there's a multitude of reasons gas stations have different prices.

“They have all their fixed costs, their payroll, rent, insurance and the bottom line is how much a gallon do they want to make and it varies. It’s up to the individuals,” said Krueger.

Average gasoline prices in Nevada have fallen 10.6 cents per gallon in the last week, averaging $3.98/g today, according to GasBuddy's survey of 1,130 stations in Nevada.

Prices in Nevada are 40.4 cents per gallon lower than a month ago and stand 23.2 cents per gallon lower than a year ago. 

“We’re at a point right now where you can’t refine a barrel of oil more cheaply," said Krueger. "The other thing is we only have a few refineries. Our gasoline comes out of the San Francisco Bay area via pipe over the Sierra. Those are all costs of making the gasoline. It has to be stored. It has to be transported.”

He also wants to remind us to “Enjoy the low prices. We expect to see them last through March, probably not April through. March, that’s based of demand and the world price of a barrel of oil.”
