“What happens when water mixes with engine oil?”- A tale of combustion, chemistry and the mysterious currents that flow within the engines that propel us.
Engine oil serves as a vital guardian, ensuring smooth operations by lubricating and safeguarding your car’s myriad moving components.
Water mixed with oil in the engine, however, diminishes the efficacy of this protective oil. Should a significant amount of oil find its way into the cooling system, the consequence is the potential destruction of your engine.

What are the risks when water mixes with oil in engine?
When water mixes with oil in engine, it diminishes the efficacy of the additives, and should a substantial amount of water infiltrate the cooling system, it has the potential to create a catastrophic situation, ultimately leading to the destruction of the engine.
Corrosion and Rust: Specifically, water stands out as a primary instigator of corrosion and rust, elements that amplify both friction and heat within the engine.
Formation of Sludge: When water mixes with oil in engine, there is a formation of sludge or thick emulsified oil. This sludge is a thick, gel-like substance that can clog oil passages and reduce the oil’s ability to flow smoothly through the engine.

Poor Engine Performance: When water mixes with engine oil it alters the chemical composition of the oil, causing it to thicken. The overall result of water mixing with engine oil is poor engine performance.
