Gasoline prices at Calhoun outlets reached $2.11 a gallon this week for low test.

Crude oil has reached an all-time high of about $54 a barrel.

Gasoline struck $2.79 a gallon in San Francisco yesterday.

"I think it's safe to say prices will go higher before they go lower," said Paul Gonzales, a spokesman for the Automobile Club of Southern California. "It's impossible to say how high and when it will reach its peak."
