Gas prices up 4 cents to $2.25 a gallon

CAMARILLO, Calif. — The average price of gasoline in the U.S. has risen four cents over the past two weeks to $2.25 a gallon for regular grade.

Industry analyst Trilby Lundberg said Sunday that retailers and refiners have upped their prices in response to a rise in the cost of crude oil.

Still, the average price per gallon is a dime less than it was a year ago.

The Lundberg Survey found the average price of midgrade gasoline was $2.53 a gallon while premium was $2.74 a gallon.

The average price for diesel in Friday's survey was $2.40 a gallon.

The highest average price for regular gas in the contiguous U.S. was $2.80 in San Francisco. The lowest was $1.91 in Baton Rouge, Louisiana.

In Washington, the cheapest gas is in Yakima County at $2.18 -$2.24 a gallon. In Seattle, the price per gallon ranges from $2.42 - $2.79.
