The Oil Drum: It’s That Time Again (or Refining 101: Winter Gasoline)

One of the things I really like about The Oil Drum is that I learn something new here almost every day. So, I thought I would return the favor by explaining in a bit more detail something you may not know.

Gas stations sell a special, more expensive fuel blend during the summer to cut down on smog during hot months. Stations nationwide will start selling a less-expensive winter fuel blend Friday, which could lead to even lower prices, analysts said.

So what does this mean, and why does it make winter gasoline less expensive?
