Does 'Winter Blend' Lower Gas Prices?

10/31/2017 - Professor of Economics James Bushnell on ABC News.

Gas prices are still expected to go up Wednesday, despite a "winter blend" of gasoline that is cheaper to produce. 

In the winter, oil refineries switch to a "winter blend," gas that evaporates easier as the demand for fuel is lower compared to the summer months. And while this gas is cheaper to produce, that does not mean savings at the pump.

James Bushnell, economics professor at University of California, Davis, said there won't be an evening out of sorts between winter gas and Wednesday's 12-cent gas tax increase. 

"The fact costs go down in California doesn't translate necessarily to retail prices going down," said Bushnell. "It's not going to offset the gas tax."
