* Oil changes: When you get your oil changed, the old oil is typically drained from the engine and discarded. In the United States, an estimated 1.3 billion gallons of used oil are generated each year, and only about half of that is recycled. The rest is often disposed of in landfills or incinerators, where it can pollute the environment.
* Oil leaks: Oil leaks can occur from a variety of sources, such as damaged gaskets or seals, or a faulty oil filter. Oil leaks can be a major source of oil waste, and they can also damage your car's engine.
* Spills: Oil spills can occur when you add oil to your car, or when you change your oil. Oil spills can be a major environmental hazard, and they can also be dangerous to your health.
