(May 21, 2019) Gas prices are as much as six cents cheaper in some states across the country on the week, which has pushed the national gas price average cheaper by a penny to $2.85 today. That average could have been even lower had a handful of Midwest states not seen prices increase by more than a nickel due to ongoing refinery maintenance, according to analysis by AAA.

“Gas prices are getting cheaper for the majority of motorists despite the fact that U.S. gasoline stocks sit at a 7 million barrel deficit year-over-year.

"Crude oil prices have remained relatively stable the past few months, which is one reason helping gas prices be cheaper than last year at this time,” said Jeanette Casselano, AAA spokesperson. “Today, motorists can find gas for $2.50 or less at nearly half of all gas stations in the country.”

Compared to last month, today’s national average ($2.85) is cheaper by a penny and is seven cents cheaper year-over-year.
