Why Does Engine Oil Smell?
Engine oil is designed to lubricate and protect the internal components of your vehicle’s engine. It’s made up of a blend of base oils and additives, which work together to prevent corrosion, reduce friction, and clean the engine. As engine oil circulates through the engine, it can pick up impurities and contaminants, which can affect its smell.
The Different Types of Engine Oil Smells
Engine oil can have a range of different smells, depending on its composition and condition. Here are some of the most common types of engine oil smells:
- Normal or fresh engine oil: This is the typical smell of new engine oil, and it’s usually a mild, slightly sweet or nutty aroma.
- Used engine oil: As engine oil is used, it can start to break down and develop a stronger, more pungent smell. This can be due to the buildup of impurities and contaminants.
- Burned engine oil: If engine oil is overheated or burned, it can develop a strong, acrid smell similar to burnt rubber or plastic.
- Contaminated engine oil: If engine oil is contaminated with dirt, debris, or other substances, it can develop a strong, unpleasant smell.
- Old or degraded engine oil: As engine oil ages, it can start to break down and develop a strong, unpleasant smell. This can be due to the breakdown of additives and the buildup of impurities.
