I can go a year before an oil change.

Economic confidence is weak because of high oil prices, but all that will change once oil is back down to $20 a barrel. But the economy is strong: we expect growth of about 3 percent this year and at least 3.5 percent next year.

Owning reserves doesn't change the price. If the price of oil goes to $125 a barrel, and China owns a field in Sudan, the price for them is still $125.

These are maintenance expenses, just like changing the oil on the car. You've got to change the oil on the car, you've got to change the mattresses, you've got to replace the carpet.

It's like servicing your own car. You can do simple things, like change the oil. But for some segment of the population, even if it's something they could fix themselves, people don't want to spend a lot of time fixing a computer. They just want it to work.

They average about 5 miles per gallon, depending on the route and the load, they change oil about every 5,000 miles and have 18 tires which are predominantly petroleum products. When oil and diesel prices go up, there is a significant impact on the industry.
