(March 27, 2018) With the arrival for spring, gas prices immediately became more expensive nationwide. The national gas price average is $2.61, which is a nickel more expensive on the week. Six states are seeing double-digit increases: Idaho (+16 cents), Utah (+14 cents), Delaware (+13 cents), New Mexico (+12 cents), South Carolina (+10 cents) and Maryland (+10 cents).

As prices soar, the Energy Information Administration (EIA) reports that demand dropped to 9.3 million barrels a day as gasoline stocks dipped (1.7 million barrels a day) on the week.

“Right now we are seeing the market starting to purge winter-blend gasoline to make room for summer-blend,” said Jeanette Casselano, AAA spokesperson. “The jump in gas prices is just the beginning for the season. AAA forecasts the national gas price average will be as much as $2.70/gallon this spring and summer.”

Today’s national gas price average ($2.61) is nine cents more than a month ago and 33 cents more expensive than this time last year.
