Why did gas prices gone down in the past weeks?

Gasoline prices, at least in many parts of the world, have fallen recently because of the drop in demand. For example the economic slowdown in the US has led to less automobile travel, thus lowering the demand for gasoline. The refiners of gasoline lower their prices to try to encourage more consumption. Supply and demand, even though some fuzzy-headed economists deny it, is still a very powerful market force. In my opinion gas goes lower because of financial crisis in America and Europe as lot of factories reduced their production masively there became lot of free oil which nobody wanted to buy so OPEC lowered dayly limits of getting oil but as usuall it doesnt work Sry for bad english..:-)
