You can directly top up oil if the car engine oil is insufficient. Faults caused by insufficient oil: "When the oil level is too low, it leads to poor lubrication on the friction surfaces of various engine components. Insufficient oil also reduces the engine's cooling and heat dissipation capability, causing internal overheating, which can further result in bearing bush burning and cylinder scoring. During driving, symptoms such as insufficient vehicle power and excessive oil consumption can be noticed." Symptoms of insufficient oil: The main symptom of engine oil burning is blue smoke coming from the exhaust pipe. Oil burning occurs when engine oil enters the combustion chamber through certain pathways and participates in combustion along with the air-fuel mixture. This is mainly caused by damaged piston rings leading to cylinder leakage, allowing oil to seep into the combustion chamber.

What does Elysee 16V mean?

Elysee 16V refers to the engine being a 16-valve model, equipped with a 16V engine. Here's an introduction about valves: 1. 'V' is the abbreviation for valve. 8V means two valves per cylinder - one intake valve and one exhaust valve, totaling 8 valves for 4 cylinders, hence 8V - this is the traditional engine design. 2. Similarly, 16V means 4 valves per cylinder (typically 2 intake and 2 exhaust valves, or sometimes 3 intake and 1 exhaust), totaling 16 valves for 4 cylinders - this is a multi-valve engine. 3. The 8V design has relatively simpler structure, lower cost, easier maintenance, and better low-speed performance, making it suitable for urban driving. 4. The advantages of 16V engines become fully apparent at high RPMs, allowing more complete fuel combustion, reducing fuel consumption, and increasing power output.

How to Repair Cracked Car Glass?

Car glass cracks need to be addressed promptly. For short cracks, repairs are possible, while for long cracks, the best solution is to replace the glass. Below is an introduction to repairing car glass cracks: 1. Short cracks in car glass are typically repaired using specialized repair tools and resin. The resin is injected into the crack using the repair tool, filling and solidifying to eliminate the gap, thereby achieving the repair. It is important to note that if the glass is cracked, repairable cracks should be fixed as soon as possible, and those requiring replacement should be addressed promptly. During driving, the windshield is subjected to wind resistance and constant vibrations. Over time, small cracks can gradually extend, lengthen, and expand in area. At this point, glass that could have been repaired may only be replaceable. 2. Long cracks in car glass are difficult to repair. The effectiveness of repairing large cracks is poor, often leaving visible marks. Additionally, the strength of the repaired windshield cannot be guaranteed, posing a risk of re-cracking and potential safety hazards. Therefore, replacing the glass is recommended. Moreover, glass replacement can be expensive, so it is advisable to use insurance coverage if available.

What to Do When the Car Key Won't Open the Door?

Modern car keys come in two types: remote keys and mechanical keys. Depending on the type of key that won't open the car door, there are different solutions as follows: 1. If the remote key won't open the door: It might be due to a dead battery in the remote key, a dead car battery, or strong signal interference nearby. In this case, replacing the remote key's battery or locating the hidden mechanical key inside the remote key can help open the door. However, manufacturers often hide the keyhole for aesthetic reasons. To use the mechanical key, look closely—usually, there's a decorative piece at the end of the door handle similar in size to the key. Pry it open to access the keyhole. 2. If the mechanical key won't open the door: There are two possibilities. One is that the car's central locking system is in an electronic lock state, requiring a wait of one to two hours for the lock to disengage before attempting again. The other is that the door lock cylinder is stuck due to long-term use and won't turn. In this case, the only options are contacting a 4S store for repairs or resorting to forceful methods, such as breaking the window.

Is It Okay to Buy a Car That Has Been in Inventory for 6 Months?

You need to check the following aspects of the car: 1. Battery and electrical circuits: Start the engine, turn on the high beams and multimedia system, then turn off the engine while keeping the power on. If the lights and multimedia system can still operate normally after more than 10 minutes, there should be no major issues; 2. Body and paint: Inventory cars are usually quite dirty. When picking up the car, carefully inspect the body for scratches or dents. You can also ask the dealer to wash the car and inspect it again after cleaning. If there are minor scratches or dents, you may get a better price; 3. Seals: Due to exposure to sun and rain, the seals on inventory cars tend to age significantly. Check all rubber sealing details, especially various sealing strips, as well as the tires, engine belts, and wipers; 4. Test drive: During the test drive, listen for any unusual noises, check if the brakes are responsive, and ensure smooth gear shifting. All these details should be thoroughly inspected.
