"There is tight supply worldwide, and we have got increasing demand from countries like India and China, which means that, any disruption in supply, or perceived disruption of supply, is going ...

In cold weather period the engine takes longer to warm up and used up more gas in the warm up before driving -- so you actually wasted about 10 minutes just to prepare the car for early morning trip (unless you put the car in a garage and plug it in to the AC to warm up the engine block ---in snowy states). Then the gas itself is mixed differently since winter air is more packed in oxygen than that of warm air, and to avoid winter pollution, some States are mixing gas with diff ratio. The winter gas is called the "bad" gas, and is cheaper to make.

I agree with 2#. In America, petrol is blended with alcohol by 10%, and diesel is blended with bean oil by 5%~20%. The biofuel is a little dear than the mineral fuel. To reduce petroleum consumption, states demand oil suppliers to increase the ratio of biofuel in summer. In winter, the ratio of biofuel must be lower, or it will be difficult to ignite and cause more maintenance.

是不是说夏天燃油贵的原因是含植物油的比例要多?而冬天这个比例要减少,因为植物油的容易凝固。
如果是的话,顺便问下为什么要采取植物油?减少污染吗?

The ethanol is used to:
reduce gas dependency
increase usage of corn and other vegetable production ---Brazil and other South American countries have TOO MUCH vegetation and LITTLE gasoline production.  They cannot sell Corn to USA because we could not eat that much.  So they use corn to make it into ethanol and stop importing gasoline!! This provides jobs and income for the corn; thus killing 2 birds with one stone and save their own economy!!
Also USA farmers had stopped farming corn for we cannot eat that much since 1980.  But with the invention of E85, the corn farmers are farming for corn to make Ethanol  and make twice as much money as corn for food (because the price of oil goes up too fast)!
Ethanol also reduces pollution.
