Where is the gear oil added and where is it placed in the Xiali A+?

The gear oil in the Xiali A+ is drained at the bottom of the gearbox and added in the middle of the gearbox housing. Introduction to gear oil: Gear oil is a type of lubricant used in various gear transmission devices. It is primarily composed of petroleum-based lubricating oil or synthetic lubricating oil, mixed with extreme pressure anti-wear agents and oiliness agents. Introduction to the gearbox: The gearbox is the transmission. The transmission is one of the most important components in a car's drivetrain. The transmission consists of two main parts: the gear transmission mechanism and the gear shifting mechanism. The main function of the gear transmission mechanism is to change the magnitude and direction of torque and speed; the main function of the shifting mechanism is to control the transmission mechanism, enabling the transmission ratio to be changed, i.e., to shift gears, thereby achieving speed and torque variation, enabling reverse driving, and allowing neutral gear.
My Xiali A+ has been running for eight years, and I'm quite familiar with changing the gear oil. There's a black nut on the left side of the transmission; just unscrew it to add the oil. You'll need to remove the left front wheel first to get a clear view of its position, and a 12-point socket wrench will do the job to loosen the nut. Remember to use GL-4 gear oil with a viscosity of 75W-90, about two liters is enough—overfilling can cause leaks. It's best to change the oil when the car is warm, as the old oil drains out more completely. The first time I did it myself, I spilled oil everywhere, and the stench lingered for three days. If you're not confident in your DIY skills, I recommend spending fifty bucks to have a repair shop handle it—much less hassle.
The hex-head plug on the side of the transmission is the fill port, which is particularly visible when crouching down to look at the inner side of the left front wheel. I usually check it during every maintenance service, as low oil level can cause gear shifting to feel rough. Use a dedicated oil gun to slowly pump oil through the fill port, and stop when oil starts flowing out of the overflow hole. Do not use regular engine oil as a substitute, as the viscosity of gear oil is crucial—insufficient viscosity can damage the synchronizer. The drain plug is located at the bottom of the transmission; remember to clean any metal shavings when changing the oil. The design of this location isn't very user-friendly, so it's advisable to wear anti-slip gloves during the operation.
The gear oil filler port of the Xiali A+ is located on the left side of the transmission housing, approximately behind the left half-shaft. After opening it, add 2 liters of 75W-90 gear oil until it overflows from the inspection hole. Last time I used a syringe to add it slowly, and it took me two hours. It's best to operate on level ground to ensure the oil level is accurate. The oil change interval is roughly every three years or 40,000 kilometers, but it should be shortened appropriately for older vehicles. It's advisable to prepare an oil drain pan, as the bolt washers can easily fall into the chassis.
