How To Dispose of Car Oil

Mike Davies | Thursday, January 19, 2023

Car oil is a vital component of modern vehicles, providing lubrication and protecting engine parts from wear and tear. However, with millions of cars on the road worldwide, the disposal of used car oil has become a major environmental concern.

Why Proper Disposal Matters

When not disposed of properly, used car oil can have a significant negative impact on the environment. It can contaminate water and soil, harm wildlife, and even lead to fires and explosions. In addition, improperly disposing of car oil can lead to costly fines and penalties.

On the other hand, recycling and properly disposing of used car oil can help protect the environment and conserve natural resources. Recycling used oil conserves a non-renewable resource (petroleum) and reduces the need for virgin oil.

The Recycling Process

Recycling used car oil is a fairly simple process. Collection centers and some repair shops typically accept used oil in either bulk or container form. The oil is then taken to a recycling facility where it is cleaned, filtered, and processed. It can then be used as a fuel or as a raw material in the manufacturing of new lubricants, industrial fuels, and other oil-based products.

Reusing Car Oil

Another way to reduce the environmental impact of car oil is to reuse it. Some individuals and small businesses may use used oil as a fuel in certain types of burning equipment. However, it is important to note that used oil should never be used as a lubricant or mixed with other oil.

Initiatives and Programs

There are a number of companies and charities that have initiatives to reduce the amount of car oil waste. Some examples include:

  • The Used Oil Recycling Program, a program run by the Environmental Protection Agency (EPA) that provides information and resources on how to recycle used oil
  • The Oil Recycling Partnership, a program run by the International Association of Oil Recycling that works to promote the recycling and proper disposal of used oil
  • Earth911, an organization that provides information on recycling and waste reduction, including the proper disposal of used car oil.

Frequently Asked Questions

Q: Can I mix used car oil with other fluids such as transmission fluid or antifreeze? A: No, used car oil should never be mixed with other fluids as it can contaminate the recycling process and make the oil less valuable as a raw material.

Q: Can I pour used car oil on the ground or in the sewer? A: No, pouring used car oil on the ground or in the sewer is illegal and can result in significant fines and penalties.

Q: How often should I change my car oil? A: The frequency of oil changes can vary depending on the type of vehicle and the type of oil used. Consult your vehicle's owner's manual or talk to a mechanic for specific recommendations.


Properly disposing of used car oil is essential for protecting the environment and conserving natural resources. By recycling or properly disposing of used oil, we can help keep our communities and the environment safe. With the help of recycling programs and initiatives, it's easy to make a difference.
