1. Sludge Formation: Brake fluid contains glycol ethers and other additives that are immiscible with engine oil. When mixed, these components can react and form sludge and deposits within the engine. Sludge can clog oil passages, restrict oil flow, and interfere with proper lubrication.
2. Loss of Lubricity: Brake fluid lacks the necessary lubricating properties required for engine oil. It does not contain the additives and base stocks found in engine oils that provide a protective layer between moving engine parts. This can lead to increased wear and tear on engine components.
3. Damage to Seals: Brake fluid can deteriorate and damage seals and gaskets used in the engine, leading to oil leaks and potential engine failure.
4. Corrosion: Brake fluid contains moisture and other corrosive elements that can cause internal corrosion of engine parts. This corrosion can weaken components and lead to premature failure.
5. Engine Performance Issues: Mixing brake fluid with motor oil can disrupt engine performance, causing rough idling, knocking or pinging sounds, reduced power, and increased emissions.
6. Engine Damage: In severe cases, the combination of sludge, loss of lubrication, and corrosion can lead to catastrophic engine damage, requiring extensive repair or even engine replacement.
It is crucial to avoid mixing brake fluid with engine oil. If accidental mixing occurs, it's important to immediately drain the contaminated oil and replace it with fresh engine oil. Flushing the engine with a compatible cleaning agent may be necessary to remove any residual brake fluid and contaminants.
