The U.S. Energy Information Administration predicted Tuesday that the national average price of gas from April through September will be $2.76 a gallon, down from $2.85 last summer.
For the entire year, the agency says the average household will spend about $100 less on fuel than last year, a savings of 4 percent.
Oil prices are up since December but still down from a year ago.
The Energy agency says the U.S. produced 12.1 million barrels of oil per day in March.
