The average price for regular gasoline at U.S. filling stations rose 6.8 cents in the past two weeks to $3.759 a gallon, according to Lundberg Survey Inc.
The survey covers the two weeks ended Aug. 24 and is based on information received from about 2,500 stations by the Camarillo, California-based company. The average is up 15 cents from a year earlier. Gasoline is 21 cents below the year-to-date high of $3.9671 on April 6.
"The rate of increase is because crude oil prices have trickled down to the retail gasoline market," Trilby Lundberg, president of Lundberg Survey, said today in a telephone interview. "I expect the price hikes will end soon or have already ended, especially as we see lower demand because of cooler weather and shorter days."

Gasoline futures on the Nymex gained 7.41 cents, or 2.5 percent, in the two weeks ended Aug. 24 to $3.078. Prices are up 21 percent from the year-to-date low of $2.5501 on June 21.
Crude oil and gasoline have risen on speculation that central banks in the U.S., Europe and China will act to bolster economies, on production outages in the North Sea and the U.S. and on concern that tension will escalate over Iran's nuclear program.
