There has been some concern in recent years about whether engine oil can cause cancer in humans. Engine oil is a mixture of chemicals that are designed to lubricate and protect the engine, but some of these chemicals may be harmful if they are ingested or inhaled.
In this article, we will explain the potential risks associated with engine oil and whether it can cause cancer.
Can Engine Oil Cause Cancer?
It is important to note that engine oil does not directly cause cancer. However, some of the chemicals found in engine oil have been linked to an increased risk of cancer in humans.
One of the most concerning chemicals found in engine oil is polycyclic aromatic hydrocarbons (PAHs). PAHs are a group of chemicals that are formed when organic matter is burned, such as during the combustion process in an engine.
PAHs have been classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen. This means that there is sufficient evidence to suggest that PAHs can cause cancer in humans. The IARC has identified several types of cancer that may be caused by exposure to PAHs, including lung cancer, skin cancer, and bladder cancer.

How Can You Be Exposed to PAHs in Engine Oil?
The most common way is through inhalation of fumes or particles that are released during the use of engine oil. This can occur if you work on cars or other machinery that uses engine oil, or if you are exposed to engine oil in a poorly ventilated area.
With that said, PAHs can also be ingested if you come into contact with contaminated soil or water, which can occur if engine oil is improperly disposed of.
It is important to note that the risk of cancer from engine oil is relatively low for the average person. Most people are not exposed to high levels of PAHs on a regular basis, and the risk of cancer is typically associated with chronic exposure over a long period of time. However, those who work with engine oil or are exposed to it on a regular basis may be at a higher risk of developing cancer.
In order to reduce your risk of exposure to PAHs in engine oil, it is important to take proper safety precautions when working with or around engine oil. This includes wearing protective clothing, such as gloves and a mask, and working in a well-ventilated area. In addition to this, engine oil should always be disposed of properly, in accordance with local regulations.
As you can see, engine oil does not directly cause cancer, but some of the chemicals found in engine oil, such as PAHs, have been linked to an increased risk of cancer in humans. The risk of cancer from engine oil is relatively low for the average person, but those who work with engine oil or are exposed to it on a regular basis may be at a higher risk.
However, by taking proper safety precautions and disposing of engine oil properly, you can reduce your risk of exposure to harmful chemicals and protect your health.
