Can Adding Sugar to the Engine Be Detected?
2 Answers
Adding sugar to the engine can be detected if it was recently added and the time is relatively short, as the sugar hasn't had time to melt yet. However, if the vehicle has been driven for a while, the high temperature of the engine will cause the sugar to melt, making it undetectable. Nevertheless, it can still be determined by checking the viscosity of the engine oil and the condition of the engine lubrication system components. Maintenance Notes: As a crystalline substance, sugar does not dissolve in engine oil. However, as the vehicle is driven and the engine block temperature rises, the sugar will gradually melt, significantly increasing the oil's viscosity. This can cause the engine to experience "bearing seizure," preventing normal circulation. If sugar has caused damage to the engine, a major overhaul is necessary. The entire oil system must be cleaned and inspected, and components such as the oil pump and oil pipes that may have become clogged will need to be replaced. It is advisable to have repairs done at an authorized service center, as although the cost may be higher, the quality is guaranteed. If repairs are done outside a service center, it is recommended to monitor the process closely if possible. Choose a repair shop with a good reputation and strong brand. Additionally, the difference between authorized service center repairs and external repairs lies in their qualifications. Authorized service centers must undergo a series of strict inspections by the automobile manufacturer before being approved, meaning they have official recognition from the manufacturer.
As someone who frequently repairs cars, I know that adding sugar to the engine can definitely be detected. Sugar melts into a sticky substance under high temperatures, clogging the fuel injectors or fuel pump, causing engine shaking and stalling. During inspection, mechanics first listen to the owner's description of issues, such as difficulty starting or poor acceleration, then use a diagnostic tool to read fault codes, revealing fuel system problems. Next, they disassemble the engine and visually spot yellowish-brown caramel residue or detect a sweet smell—these anomalies are very noticeable, requiring a thorough cleaning of the entire system during repairs. I recommend checking the fuel filter during regular maintenance to prevent such sabotage. In short, adding sugar not only makes it easy to detect but also leads to thousands in repair costs. Car owners should protect their vehicles and avoid such pranks—safe driving comes first.
