What do you do with old Car Oil?

If you own a car, you know that regular oil changes are essential for keeping your vehicle running smoothly. But what do you do with the old oil once it’s drained from your car?

Many people are unsure of how to properly dispose of old car oil, and unfortunately, improper disposal can have serious consequences for the environment. In this article, we’ll discuss the importance of proper oil disposal and provide some tips on how to dispose of old car oil safely and responsibly.

Why Is Proper Oil Disposal Important?

Environmental Impact

Improper disposal of old car oil can have a significant impact on the environment. When oil is dumped into the ground or poured down a drain, it can contaminate soil, water sources, and harm wildlife.

According to the Environmental Protection Agency (EPA), just one gallon of used oil can contaminate one million gallons of water. This can have devastating effects on aquatic life and the ecosystem as a whole.

Legal Consequences

Improper disposal of old car oil is not only harmful to the environment, but it can also result in legal consequences. In many areas, it is illegal to dispose of used oil in the trash or pour it down a drain. Violators can face hefty fines and even criminal charges.

How to Dispose of Old Car Oil

Use a Certified Oil Collection Company

If you are unable to take your old car oil to a recycling centre, you can also hire a certified oil collection company to pick it up for you. These companies specialise in the proper disposal of used oil and will ensure that it is recycled or disposed of safely.

Reuse It

If you are feeling particularly eco-friendly, you can also reuse your old car oil. Used oil can be filtered and used as a lubricant for other machinery or even as a fuel source for certain types of heaters. However, it is important to note that this should only be done by those with proper training and equipment to ensure safety.

Never Pour It Down a Drain or on the Ground

Under no circumstances should you ever pour old car oil down a drain or onto the ground. This can have serious consequences for the environment and can also result in legal consequences for you.

Tips for Proper Oil Disposal

Store It Properly

When storing old car oil, it is important to use a container that is specifically designed for oil storage. This will help prevent spills and ensure that the oil is properly contained.

Additionally, make sure the container is labelled as “used oil” to prevent confusion and potential accidents.

Check Local Regulations

Before disposing of old car oil, it is important to check your local regulations. Some areas may have specific guidelines for oil disposal, and it is important to follow them to avoid any legal consequences.

Don’t Mix It with Other Substances

Never mix old car oil with other substances, such as antifreeze or gasoline. This can make it difficult to properly dispose of and can also be dangerous.

Consider Switching to Synthetic Oil

Synthetic oil is becoming increasingly popular for its longer lifespan and better performance. But did you know that it is also more environmentally friendly?

Synthetic oil produces less waste and is easier to dispose of properly. Consider making the switch to synthetic oil for a more eco-friendly option.

What Happens to Old Car Oil After It Is Disposed Of?

After old car oil is properly disposed of, it goes through a process called re-refining. This process removes impurities and contaminants from the oil, making it suitable for reuse.

Re-refined oil can be used as a base for new motor oil, industrial lubricants, and even as a fuel source. This process not only helps reduce the amount of oil that ends up in landfills or the environment, but it also conserves natural resources.


Proper oil disposal is essential for protecting the environment and avoiding legal consequences. By taking your old car oil to a recycling centre or using a certified oil collection company, you can ensure that it is disposed of safely and responsibly.

Remember to always store old car oil properly, check local regulations, and never mix it with other substances. And if you want to make a more eco-friendly choice, consider switching to synthetic oil. By taking these simple steps, you can do your part in protecting the environment and promoting responsible oil disposal.
