A survey says the average price of a gallon of regular gasoline in the U.S. is holding steady, rising 3½ cents over the last three weeks to $3.69.

Industry analyst Trilby Lundberg said Sunday that crude oil prices are little changed and strong refinery output has quenched higher demand. She anticipates minor price declines ahead.

The survey taken Friday shows the average price for a gallon of midgrade gas was $3.88 and the average price for a gallon of premium was $4.03. Diesel averaged $3.96 a gallon.

Of cities surveyed in the continental U.S., Baton Rouge, Louisiana, had the lowest average price at $3.33 a gallon. San Francisco had the highest average at $4.14 a gallon.
