Can the ECO mode be turned on for a long time?

ECO mode can be turned on for a long time. ECO mode, also known as economy mode, is effective in saving fuel when the vehicle frequently drives in congested urban road conditions. Under ECO mode operation, the carbon deposits in the engine are almost the same as those produced under normal operating mode, so the ECO mode can be kept on all the time. The main principle of ECO mode is not complicated. It mainly involves a comprehensive judgment and analysis of factors affecting fuel consumption during vehicle movement, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the appropriate amount of fuel to be supplied to the engine for operation, effectively reducing fuel consumption compared to normal driving mode. Simply put, it controls the engine speed with reasonable gears to reduce unnecessary fuel consumption.
As a veteran driver with 20 years of experience, I can tell you that ECO mode can definitely be kept on long-term. I've barely turned it off since buying the car. During daily city commutes, using ECO has helped me save at least 15% on fuel costs, significantly reducing my monthly gas bills—which is crucial for my family budget. There are no downsides to keeping it on long-term; the engine and transmission operate normally, just requiring regular maintenance to check fluids and spark plugs. However, note that power may weaken on highways or uphill, and acceleration response can be slightly slower when overtaking. That's why I keep it on during rainy days or heavy traffic—safety first. Remember, the core of ECO mode is optimizing driving habits by reducing sudden acceleration, which is also eco-friendly. After over 5 years of use, my car's performance remains stable, fully meeting long-term usage design. Overall, this mode is highly adaptable, and keeping it on is absolutely cost-effective.
