Does driving in eco mode save fuel?

Driving in eco mode does save fuel. The main principle of eco mode is: during vehicle operation, it comprehensively evaluates the automatic transmission gear, engine speed, and transmission oil temperature to control the engine speed with appropriate gears. The onboard computer then calculates the optimal fuel amount to supply the engine for operation. As an energy-saving mode for vehicles, eco mode is primarily divided into active and passive types. The passive type doesn't have a dedicated button but includes a reminder function. When the vehicle speed exceeds 20 km/h, eco mode intelligently assesses the fuel consumption and displays it in green on the dashboard. The eco mode automatically deactivates when encountering uphill climbs or acceleration.
With over a decade of driving experience, I can confirm that ECO mode genuinely helps save fuel. It adjusts throttle response and shift logic to make acceleration smoother, reducing unnecessary fuel consumption. It's particularly effective in city traffic jams—the car won't suddenly lurch forward, which actually lowers engine load and can cut fuel consumption by around 10%. From my own real-world testing, using ECO mode during daily commutes noticeably slows the fuel gauge drop, saving a good amount of money. However, it's best to turn it off on highways because the slower acceleration response could compromise overtaking safety. Remember, combining ECO mode with steady-speed driving and regular vehicle maintenance makes fuel savings more sustainable.
As a commuter, I find it really worthwhile to use ECO mode on my daily drive to work. In congested areas, the car becomes much more docile and fuel consumption noticeably drops, saving me around a few dozen yuan in gas per month—quite cost-effective. The principle of ECO mode is to optimize the engine's operating state, avoiding fuel waste during sudden acceleration. However, I turn it off on mountain roads or when quick response is needed, otherwise climbing becomes strenuous. Over time, ECO not only saves fuel but also reduces engine wear and extends the vehicle's lifespan. Just don’t expect it to solve everything—combining it with other fuel-saving habits works better.
