What Causes Car Oil to Smell

You’re smelling car oil because of the chemical compounds it contains. These compounds, such as hydrocarbons, sulfur, and nitrogen, create an aromatic blend that’s familiar to many.

If the oil has been sitting for a while, the smell can become pungent and change in intensity. As the oil ages, it can become more volatile, producing an even more pungent odor.

Additionally, the oil can mix with other substances inside the car, such as spilled fuel, and produce a distinct smell. It’s also important to note that the type of oil used in a car can also affect the smell, as some oils are more volatile than others.

All of these factors can contribute to the smell of car oil.
