CAMARILLO, Calif. (AP) — The U.S. average price of regular gasoline dropped 9 cents over the past two weeks to $2.35 a gallon.

Industry analyst Trilby Lundberg said Sunday that prices have plummeted from five weeks ago as U.S. retailers and refiners slashed their profit margins even as crude oil prices rose.

She says she expects prices could drop another few cents due to ample gasoline supplies and strong consumer demand.

The national average price of diesel fell 5 cents in the past two weeks to $2.58 a gallon.

In the lower 48 states, the lowest average price of regular gasoline was $1.92 per gallon in Baton Rouge, while the highest was $3.06 per gallon in Los Angeles.

In Nebraska, the average price of a gallon of regular is $2.34, according to GasBuddy.com.
