What are the consequences of adding sugar to engine oil?

[EleanorMarie]

Adding sugar to engine oil will cause the oil to become sticky when heated, thereby reducing its fluidity. Detailed consequences of adding sugar to engine oil: If a spoonful of sugar is added to the engine oil, it will become sticky when the engine heats up, reducing the oil's fluidity. This can negatively impact both fuel consumption and engine performance. If left unaddressed, clogging of the oil passages may occur, leading to severe engine damage such as bearing seizure, and in extreme cases, complete engine failure. Principle behind the severe consequences of adding sugar to engine oil: As the engine operates and generates continuous high temperatures, the sugar gradually melts into a gel-like substance, making the oil extremely viscous. This prevents proper oil circulation and effective engine cooling. With the blockage of oil pipes and pumps, the engine will progressively exhibit symptoms such as power loss, increased noise, sudden stalling, and failure to start.
