Gasoline prices dipped by one cent to $2.18, after weeks of increases that followed drops earlier in the year as a result of the pandemic.

As COVID-19 case numbers surpass 4 million, demand for gasoline is weakening across the country. The lower demand contributed to a cheaper national average on the week; this is the first time since late April that the national average has declined.

Today’s national average is 56 cents cheaper than last year, according to AAA. Motorists can find gas for $2.25 or less at 70% of gas stations across the country.

“Pump prices are mostly pushing cheaper across the country as gasoline demand wanes over the past few weeks,” said Jeanette Casselano, AAA spokesperson. “Gas prices are likely to fluctuate throughout the rest of the summer due to COVID-19 concerns, with the national average possibly reaching $2.25.”

The nation’s top 10 largest weekly changes include Michigan (down 5 cents), Indiana (down 4 cents), North Carolina (down 4 cents), Idaho (up 3 cents), Wyoming (up 3 cents), Maryland (up 3 cents), Texas (down 3 cents), California (up 2 cents), Wisconsin (down 2 cents) and Florida (down 2 cents).

Meanwhile, the nation’s least expensive markets include Mississippi ($1.83), Louisiana ($1.85), Arkansas ($1.88), Texas ($1.88), Alabama ($1.89), South Carolina ($1.89), Missouri ($1.90), Oklahoma ($1.90), Tennessee ($1.91), and Kansas ($1.97).
