Sept. 20 (Bloomberg) -- Gasoline fell amid below-average volume, capping a third consecutive weekly decline on speculation production and supply will be ample to meet declining demand after the end of driving season.

“Winter-grade margins were particularly good a few weeks back and now they’re not and we’re going into a seasonally low period of demand,” said Amrita Sen, chief oil market strategist at Energy Aspects Ltd., a research company in London.
