Why Change Oil While the Engine is Hot?
Changing oil while the engine is hot may seem counterintuitive, as most people assume that oil is best changed when the engine is cold. However, there are several reasons why some mechanics and car owners prefer to change oil while the engine is still warm:
- Hot oil is thinner and easier to drain, making the process less messy and more efficient.
- The oil filter is more likely to be clean and free of debris when the engine is hot, making it easier to remove and replace.
- The engine is more likely to be in a state of equilibrium when hot, which can make it easier to diagnose any issues or problems with the oil system.
Risks Associated with Changing Oil While the Engine is Hot
While changing oil while the engine is hot may have some benefits, it also carries some risks:
- The engine may be more prone to oil leaks and spills, as the hot oil can cause the seals and gaskets to expand and become loose.
- The oil filter may not be properly seated or secured, which can lead to oil leaks and other problems.
- The hot oil can cause the engine to overheat, leading to damage to the engine block, cylinder head, or other components.
