Reasons why adding oil to a hot engine is not advisable:
* Burns: Hot oil can cause severe burns if it splashes on your skin.
* Spills: The engine is under pressure when hot, which can make it difficult to add oil without spilling. Spilled oil can be a fire hazard and contaminate the environment.
* Damage to the engine: Adding cold oil to a hot engine can cause thermal shock, which can damage engine components.
* Incorrect level: When the engine is hot, the oil expands, making it difficult to determine the correct oil level.
Best Practice:
* Allow the engine to cool down before adding oil.
* Use a funnel to prevent spills.
* Check the oil level after the engine has been off for at least 10 minutes.
Exceptions:
* Emergency situations: If your engine is running low on oil and you are unable to stop immediately, you can add a small amount of oil to prevent damage. However, it is important to address the underlying issue as soon as possible.
* Specific instructions: Some vehicles may have specific instructions for adding oil while the engine is hot. Always refer to your owner's manual for guidance.
In general, it is always best to add oil to a cold engine to ensure safety and prevent damage.
