What in motor oil is carcinogenic?

Motor oil may contain various carcinogenic compounds, primarily polycyclic aromatic hydrocarbons (PAHs) that can form during the refining process or from the combustion of fossil fuels. Additionally, some additives used in motor oils, such as certain detergents and anti-wear agents, may also pose potential health risks. Prolonged exposure to these substances, especially through skin contact or inhalation, could increase the risk of cancer. It's essential to handle motor oil safely and follow proper disposal guidelines to minimize exposure.
