The national average price for gasoline continued to rise slightly, now up to $1.84, and approximately 40 states carry an average of price of $2 per gallon or less, according to AAA.

Gasoline prices are still cheaper on the month and year – three cents and $1.02 less, respectively, according to AAA.

“Pump prices are fluctuating throughout the country as demand increases and gasoline stocks decrease,” said Jeanette Casselano, AAA spokesperson. “The boost in demand continues to push pump prices up around the country, as more states re-open businesses. Motorists in the Great Lakes, Central, South and Southeast states are seeing the most volatility at the pump.”

The Energy Information Administration’s (EIA) latest data report showed demand for gasoline increased by 800,000 barrels per day to 6.7 million barrels per day last week, which is 3.2 million barrels per day less than last year at this time. Gas demand is expected to continue to grow, leading pump prices to continue their increase.

The nation’s largest weekly increases include Michigan (up 31 cents), Ohio (up 28 cents), Indiana (up 26 cents), Illinois (up 26 cents), Wisconsin (up 23 cents), Kentucky (up 15 cents), Iowa (up 14 cents), Minnesota (up 11 cents), Oklahoma (up 10 cents) and Arkansas (up 9 cents).

The nation’s least expensive markets include Oklahoma ($1.47), Arkansas ($1.48), Missouri ($1.48), Mississippi ($1.49), Kansas ($1.50), Texas ($1.51), Alabama ($1.55), South Carolina ($1.57), Tennessee ($1.60) and Louisiana ($1.60).
