- Overheating engine: If your engine is running too hot, the oil can break down and burn, producing a strong, acrid smell.
- Low oil levels: If your oil levels are too low, the engine’s moving parts can become damaged, causing the oil to burn and produce a strong smell.
- Dirty or contaminated oil: If your oil is dirty or contaminated with debris, it can break down and burn, producing a strong, unpleasant smell.
- Worn or damaged engine components: If your engine’s components, such as piston rings or valve seals, are worn or damaged, they can allow oil to leak into the combustion chamber, where it can burn and produce a strong smell.

In addition to these common causes, there are several other factors that can contribute to burnt engine oil smell, including:
- Driving habits: Aggressive driving, such as rapid acceleration or braking, can cause the engine to work harder, leading to increased heat and oil breakdown.
- Environmental factors: Extreme temperatures, humidity, and air pollution can all contribute to engine oil breakdown and burning.
- Age and condition of the engine: Older engines or those with high mileage may be more prone to oil burning and breakdown.
