Gas prices drop sharply across U.S.

CAMARILLO, Calif. -- A national survey shows gas prices tumbled 35 cents in the last two weeks, following price declines in world oil markets.

The average price of a gallon of regular gasoline at self-serve stations was $3.31 Friday. Mid-grade was at $3.45 and premium was $3.57. Diesel averaged $3.95.

That's according to the Lundberg Survey of 5,000 gas stations nationwide, released Sunday.

Gas was cheapest in Wichita, at $2.79 for a gallon of regular. It was most expensive in Honolulu at $3.91.

The price of a barrel of crude plunged below $78 last week reflecting the pessimism of investers during the global economic crisis.
