Car engine oil is considered to be at a normal level when the oil quantity is between the two marks on the dipstick. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is categorized by quality into Group I, Group II, and Group III base oils, with Group I and II being mineral oils and Group III being synthetic base oils. There are various types of additives, and the quantity and quality of these additives directly affect the API quality rating of the lubricating oil.

How to Read Traffic Lights When Driving?

Vehicles cannot go straight or turn left when the arrow light is red for right turns, prohibiting right turns, while a circular light showing red allows right turns if there's no accompanying 'no right turn' sign. At intersections when the green light is on, proceed in the indicated direction, especially following arrow light directions. When the yellow light is on, vehicles that have already crossed the stop line may continue through. Pedestrians on crosswalks at traffic light intersections have the right of way; vehicles permitted to turn right must yield to pedestrians.

What to Do When the Trunk Lock Won't Open?

Solutions for a trunk lock that won't open: Enter the car, fold down the rear seats, open the trunk interior panel, and manually pull the unlocking lever to unlock it. The reasons why the trunk lock won't open are as follows: 1. Linkage rod issue: If you frequently use the key to open the trunk, the linkage rod may be broken. 2. Lock cylinder problem: If you always use the remote to open the trunk, the lock cylinder may be dirty or rusted. Spraying rust remover into the lock cylinder a few times can help open it.

How to Drive on the Road for Beginners?

When driving, pay attention to the choice of time. If you are driving eastward, try to avoid the hours around 8 or 9 in the morning. If another vehicle is overtaking you while driving, make sure to yield. When pulling over to the side of the road, always check the right rearview mirror to avoid potential traffic accidents. Maintain a safe distance from the vehicle in front of you while driving to prevent rear-end collisions due to lack of skill. On highways, be mindful of your speed and keep it within a range that you feel comfortable controlling.

How to Reset the Urea Solution Warning Light?

Low urea pressure with high urea consumption: If the dashboard warning light frequently flashes, indicating low urea pressure and high urea consumption, replacing the water heating valve will fix the problem. 3. Insufficient power with abnormally high or low urea consumption: If the warning light stays on constantly, the vehicle lacks power, and torque is limited to 1800 RPM, indicating the SCR system is not functioning properly with either excessively high or low urea consumption, replacing the urea pump and power supply module connector is necessary.

What to Do When the Windshield Wiper Doesn't Work?

Solutions for a non-functioning windshield wiper: 1. Blown fuse: Open the fuse box and check if the corresponding fuse (refer to the manual on the cover for specifics) has blown. If so, simply replace it, but remember to turn off all the car's electrical systems before replacement. 2. Burned-out motor: The probability of a motor burning out is actually quite low, but it could be due to quality control issues. With the car's ignition switch in the 'on' position, try opening the hood and activating the wiper. If it's not damaged, you should hear the motor running, and the sound is quite noticeable. If there's no sound and you detect a slight burning smell, it's likely that the motor is damaged.
