Oil prices tumble in biggest weekly drop ever. Gas prices to drop at pumps in 3... 2... oh, who are we kidding (144)
It takes a good three or four weeks for oil to hit the pumps. The price of gas will probably increase a little before it comes down.
When prices are going up, gas stations base their price on what they believe their next tankload will cost. That's why price spikes in the futures markets tend to hit the pump in hours rather than days.
When prices are going down, gas stations base their price on what they paid for their last tankload. That's why price drops the futures markets tend to hit the pump in weeks.
