I'm an expert in the field of automotive engineering and safety, and I'm here to provide you with a detailed explanation regarding the flammability of motor oil.
Motor oil, also known as engine oil, is a lubricant that is essential for the proper functioning of an internal combustion engine. It reduces friction between moving parts, helps to cool the engine, and also cleans and protects engine components from wear and tear. However, it's important to understand the properties of motor oil in terms of its flammability to ensure safety and proper maintenance practices.
Flammability of Motor Oil
Motor oil is not inherently flammable in its liquid state under normal operating conditions. It is designed to withstand high temperatures without igniting. However, there are certain circumstances under which motor oil can become a fire hazard:
1. Evaporation and Fumes: As you mentioned, motor oil begins to evaporate at temperatures around 400°F (200°C). When it evaporates, it produces flammable vapors. If these vapors come into contact with a source of ignition, such as a hot engine component or an open flame, they can ignite and potentially cause a fire.
2. Contact with Hot Components: If motor oil leaks or spills onto hot parts of the engine, such as the exhaust manifold or other hot exhaust components, it can ignite. This is particularly dangerous because the oil is not designed to be in contact with these high-temperature areas.
3. Pressure Buildup: In some cases, pressure can build up within the engine, especially if there is a blockage or if the oil is not being circulated properly. This pressure can force oil out of its intended pathways and into contact with hot engine parts, increasing the risk of a fire.
4. Overheating: If the engine is overheating, it can cause the oil to reach temperatures where it may start to break down and produce flammable gases. Prolonged overheating can be a serious safety concern.
5. Contamination: Contaminants such as dirt, water, or fuel can mix with the oil, altering its properties and potentially making it more prone to ignition.
Safety Precautions
To mitigate the risk of motor oil igniting, it is crucial to follow proper maintenance practices:
- Regularly check and change the engine oil according to the manufacturer's recommendations.
- Ensure that the engine is not leaking oil and that any leaks are promptly repaired.
- Monitor engine temperatures and address any overheating issues immediately.
- Keep the engine compartment clean and free of debris that could potentially ignite.
- Use the correct type and grade of motor oil specified by the vehicle manufacturer.
Conclusion
While motor oil is not typically flammable in its liquid state, it can become a fire hazard under certain conditions. Understanding these conditions and taking the necessary precautions can help prevent accidents and ensure the safe operation of your vehicle.

"...oil to escape and come into contact with engine parts. The oil would catch fire when it contacted the exhaust manifold or hot exhaust components..." Engine oil starts to evaporate at around 400F (200C). The fumes are then flammable so if the oil is built up on some hot parts of the vehicle it could be dangerous.
