* Chemical incompatibility: Brake fluid will react with the engine oil, breaking down its lubricating properties. This will lead to drastically reduced lubrication, causing increased friction and wear on all moving parts within the engine.
* Sealing issues: Brake fluid can swell and damage rubber seals and gaskets within the engine. This can lead to leaks of oil, coolant, or even fuel.
* Corrosion: Brake fluid is highly corrosive to many engine metals. This can lead to significant corrosion and damage over time.
* Increased viscosity: Brake fluid can increase the viscosity of the engine oil, making it thicker and harder to pump. This can lead to reduced oil flow, further damaging engine components due to lack of lubrication and potential overheating.
* Foam formation: The mixing of brake fluid and engine oil can cause foaming, reducing the oil's ability to lubricate effectively.
The result of even a small amount of brake fluid contamination could range from:
* Reduced engine performance: Noticeable loss of power and efficiency.
* Engine noises: Increased ticking, knocking, or other unusual sounds.
* Premature wear and tear: Rapid deterioration of bearings, piston rings, and other internal components.
* Engine failure: In severe cases, the engine could seize up completely due to lack of lubrication and increased friction.
If you suspect brake fluid has been mixed with your engine oil, immediately change the oil and filter. A thorough engine flush might also be necessary, depending on the quantity of contamination. It's best to consult a mechanic to assess the damage and recommend the appropriate course of action. Ignoring the problem will almost certainly lead to costly repairs or complete engine failure.
