Can Adding Brake Fluid to Your Oil Cause Damage to Your Engine?by Daniel Pearson
It has been said that pouring brake fluid into a vehicle's oil tank will help to clear up sludge, but this could not be further from the truth. Adding break fluid to your oil could seriously damage the engine.
Damage to Engine Seals
Mixing brake fluid with oil causes the rubber seals inside an engine to swell, tear and leak, requiring an expensive reseal job to correct.
Differences in Fluids
Brake fluid is hydraulic fluid, which has a different composition than oil. Just as pouring oil into brake lines would cause brake failure, adding brake fluid to the oil tank would cause the engine's seals to break down.
Effect on the Engine
Adding any fluid other than oil causes an engine to break down, and can require a costly engine block replacement.
Dealing with Sludge
If there is reason to suspect a sludge problem exists in you vehicle's engine, take the vehicle to an oil-change facility. If you know the vehicle has a sludge problem take it to a mechanic. Use an engine flush to deal with this issue before it becomes a problem.
Change Your Oil
Changing motor oil on a regular basis -- about every 3,000 miles -- this keeps sludge from building up in an engine and helps to extend the life of the vehicle.
