CAMARILLO, Calif. — The average U.S. price of regular-grade gasoline held steady over the past two weeks at $2.25 per gallon.

That’s 50 cents below the average pump price from a year ago.

Industry analyst Trilby Lundberg of the Lundberg Survey said Sunday the prices are stable because crude oil prices barely changed and the U.S. has a glut of gasoline yet a weak demand as wide-ranging unemployment persists.

Nationwide, the highest average price for regular-grade gas is in the San Francisco Bay Area at $3.31 per gallon. The lowest average is in Baton Rouge, La., at $1.77 per gallon.
