Does driving the Sylphy in ECO mode harm the car?

[DiJack]

Enabling ECO mode in the Sylphy does not harm the car, but it should not be kept on for extended periods. This is because ECO mode primarily makes comprehensive judgments and analyses during vehicle movement regarding factors that affect fuel consumption, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to supply the engine for operation, effectively reducing fuel consumption compared to normal driving mode. However, prolonged use of ECO mode, while lowering fuel consumption, can accelerate the formation of engine carbon deposits. This is detrimental to the engine, increasing its pressure and subsequently leading to higher fuel consumption. Therefore, although ECO mode saves fuel, it should be used selectively. When to use ECO mode: ECO mode is most effective in urban traffic congestion. In stop-and-go city traffic, strong power is not required, and fuel consumption is high. Activating ECO mode in such conditions not only reduces fuel consumption but also enhances driving comfort. When not to use ECO mode: 1. When driving at high speeds (up to 100km/h), even if ECO is activated, the vehicle's computer will prioritize speed, causing the ECO mode to automatically deactivate. 2. When high torque output is needed, such as when climbing hills, the engine computer will prioritize ensuring sufficient power to drive the vehicle, automatically deactivating ECO mode.
