The Environmental Impact of Improper Disposal

Before we dive into the “how-to,” it’s crucial to understand the “why.” Improper disposal of used motor oil can have devastating environmental consequences.

  • Water Contamination: Just one gallon of used motor oil can contaminate one million gallons of fresh water. This is enough to supply a city of 50,000 people for an entire year.

  • Soil Pollution: When oil is dumped on the ground, it seeps into the soil, rendering it infertile and potentially contaminating groundwater.

  • Harm to Wildlife: Oil spills, even small ones from improper disposal, can harm birds, fish, and other wildlife by coating their feathers or skin, impairing their ability to move, find food, or regulate body temperature.

  • Air Quality: Burning used oil as fuel without proper controls releases toxic pollutants into the atmosphere.

Understanding these risks underscores the importance of proper disposal. Knowing how to recycle used car oil is not just a convenience; it’s an environmental imperative.

The Re-Refining Process: How Used Oil Becomes New

The magic behind why is used car oil recycled lies in the re-refining process. This isn’t just filtering out impurities; it’s a sophisticated industrial procedure.

  1. Collection: Used oil is collected from various sources, including auto repair shops, quick-lube centers, industrial facilities, and DIY collection points.

  2. Dehydration: Water and light fuels are removed from the used oil.

  3. Fuel Stripping: Remaining fuels and antifreeze are separated.

  4. Vacuum Distillation: The oil is heated under a vacuum, separating it into different fractions, similar to how crude oil is refined.

  5. Hydrotreating: The distilled fractions are treated with hydrogen to remove impurities and improve the quality of the base oil.

  6. Blending: The re-refined base oils are then blended with additives to create new lubricating oils that meet the same strict performance standards as virgin oils.

This process means that a gallon of used oil can produce the same quantity of high-quality lubricating oil as 42 gallons of crude oil. It’s an incredibly efficient and eco-friendly cycle.
