This motor turns a generator, which makes the electricity. Just think, the fuel used to create electricity took several million years to make, and it's used up in just seconds. That means that you should turn lights and TVs off when you're not using them. Here in the lower part of the tower, the crude oil vapor condenses, and we get lubricating oil. When Mom or Dad says that the car is a quart low, they mean that the car needs more oil from lubrication or grease.
Machines have metal surfaces rubbing against each other.
This generates heat. The oil keeps the motor from overheating and allows it to run efficiently. In addition to our cars, practically every machine in every factory uses lubricating oil to keep the machines running smoothly. Now way down here at the bottom is the real heavy stuff called sludge. It should come as no surprise that this is used to make asphalt.
