While driving, the engine RPM of a typical fuel-injected vehicle is most fuel-efficient at around 2200-2500. Introduction to downshifting: It is recommended to downshift when the RPM is below 1500. The engine is more fuel-efficient at 2000-2500 RPM (with slight variations depending on the engine), with moderate torque and relatively low noise, making it suitable for normal driving. Introduction to upshifting: At 2500-3500 RPM, the engine torque is more suitable for overtaking or climbing steep slopes, but fuel consumption increases and noise becomes louder. Above 3500 RPM is not recommended for prolonged operation, as the engine consumes significantly more fuel and produces very loud noise in this range.

As a long-time driver of the Aoling CTS, I've found that this truck's optimal economical RPM range typically operates between 1800 and 2200 revolutions per minute, which maximizes fuel efficiency and minimizes wear. Under light load conditions, it's best to maintain around 1800 RPM for smooth driving. When fully loaded or climbing hills, slightly increasing to above 2000 RPM helps prevent engine strain. For city driving at 40-50 km/h, keeping the RPM steady at 2000 is ideal, while maintaining 80 km/h on highways without frequent fluctuations is recommended. Installing an RPM monitoring gauge is highly practical for real-time adjustments. Cultivating gentle acceleration habits—avoiding sudden throttle inputs or coasting in neutral—saves fuel and reduces emissions. Regular maintenance, including oil changes and air filter replacements, is also crucial to ensure stable operation within the optimal RPM range.

Based on practical testing experience, I've observed that the Aoling CTS engine operates most economically within the 1900 to 2100 RPM range, achieving optimal fuel efficiency while maintaining balanced performance. For instance, maintaining 1800 RPM suffices when unloaded, but with loads exceeding 1 ton, it's advisable to increase to 2100 RPM to handle the demand. Using a smartphone app connected to the OBD port for real-time monitoring reveals that lower RPMs in urban areas enhance fuel savings, while briefly boosting to 2500 RPM for overtaking remains safe. Modern driving techniques suggest optimizing gear shifts and speed control: stabilizing RPMs around 55 km/h minimizes sudden accelerations or decelerations. Over time, gentle driving habits not only reduce engine wear, extending vehicle lifespan, but also lead to significant cost savings.

I've been driving the Aoling CTS for over three years and found the optimal RPM to be around 2000. For daily light loads, 1800 RPM is sufficient, while heavy loads require 2200 RPM to maintain power. Simple operation: monitor the dashboard to avoid too low or high RPM, preventing excessive vibration or sudden fuel consumption spikes. Cultivate smooth driving habits for fuel efficiency, durability, and clutch protection.
