Can Adding Sugar to the Engine Go Undetected?

[OJuliana]

Adding sugar will always be detected, regardless of the amount. Here are the relevant details: Reasons it can be detected: If sugar is added to the engine and the time elapsed is short, the sugar may not have melted yet and can be detected. If the vehicle has been driven for a while, the high temperature of the engine will melt the sugar, but it can still be identified by checking the viscosity of the engine oil and the condition of the engine's lubrication system components. Effects of adding sugar: Sugar, as a crystalline substance, does not dissolve in engine oil. However, as the engine heats up during operation, the sugar will gradually melt, significantly increasing the oil's viscosity. This can cause the engine to "seize," preventing normal oil circulation. The damage caused by adding sugar necessitates a major engine overhaul. The entire oil system must be cleaned and inspected, and components like the oil pump and oil lines that may be clogged will need to be replaced.
