Antifreeze should not be mixed with oil. True or False?

Answer: True.

Antifreeze is a chemical compound primarily used in cooling systems of vehicles to lower the freezing point of the coolant, preventing the engine from freezing in cold weather and allowing it to operate at higher temperatures without boiling over. On the other hand, oil serves a different purpose; it lubricates engine components and helps in heat dissipation.

Mixing antifreeze with oil can lead to various problems. The two substances have different properties and can react adversely, leading to oil emulsification, which substantially degrades the oil's lubricating properties. This can result in increased engine wear, damage, or even catastrophic failure. Therefore, it is crucial to keep antifreeze and oil separate to ensure that both systems operate effectively and protect the engine components. Mixing them is not recommended and can cause significant engine issues.
