OPEC is looking to stem the slide down by cutting production. Who knows what effect that has. I think the market has realized that $4 is unsustainable.
Don't know about you folks but this is the cheapest I've seen in over three years, and it was the $2 gas that caused me to purchase a fuel efficient car 5 years ago. Of course, that was when I still lived in California and gas is still over $2.50 in most areas now.
If the cost a barrel stays down, gas should stay down too. No telling what will happen if it goes up.
