Should I use D gear or S gear on the Qijun Highway?

Use D gear on the Qijun Highway. Transmission: Because the transmission control module (TCM) employs an imprecise reasoning theory strategy. It optimizes the transmission based on the vehicle's driving conditions, somewhat resembling the learning function of artificial intelligence. D Gear: This is the most common gear in automatic transmission vehicles, usually located in the middle-rear position of the gear shift console, behind the N gear. Its purpose is to automatically select the appropriate gear when the vehicle is moving forward. D gear is a forward gear, but forward gears are not limited to D gear; they also include M gear, S gear, L gear, and numerically labeled restricted gears such as 1st, 2nd, and 3rd. Driving gears consist of both forward gears and reverse gears, while the counterpart to driving gears is the neutral gear, which means no gear is engaged.
On the highway, I usually prefer using the D gear because it's designed for smooth and comfortable driving, making it ideal for long-distance cruising. The Qijunlu Highway section has heavy traffic, and using the D gear for automatic shifting keeps the engine operating in the optimal RPM range, saving fuel and reducing noise. If I need to accelerate for overtaking, temporarily switching to the S gear provides a more responsive throttle, enhancing power and making overtaking easier. However, the S gear keeps the engine at higher RPMs, increasing fuel consumption and noise, and prolonged use may accelerate component wear. I often test drive on the highway on weekends, and after trying the S gear, fuel consumption noticeably increased by over 10%. Regular maintenance includes checking the transmission fluid to ensure everything is functioning properly—safety always comes first when driving.
As a stay-at-home dad who has been driving for years, I pick up my kids on the highway every day and habitually choose D gear. It's much more fuel-efficient than S gear, smooth as cooking at home. The Qijunlu Highway isn't particularly steep, so D gear is sufficient, making the drive quiet and worry-free while keeping fuel consumption at a minimum. Occasionally, when there's an urgent need to overtake, I switch to S gear for a quick acceleration, but it consumes fuel quickly and is noisy, so I generally avoid using it too much. The transmission is like home appliances—it needs careful maintenance without unnecessary tinkering. I always remind myself to perform regular maintenance, such as checking the engine and tires, developing good habits to save money and stay safe.
