What Causes Engine Sludge?

It may be caused by oil leakage during oil addition or oil seepage. The following are the hazards of excessive engine sludge: 1. It greatly reduces the heat dissipation capacity of the cylinder block, leading to excessively high oil temperature and a decrease in engine power. 2. It increases the flow resistance of the oil, reduces the oil flow rate, and thus affects the lubrication effect of the oil. 3. It clogs the engine oil passages, resulting in insufficient lubrication between engine components, and in severe cases, it can cause bearing seizure and crankshaft locking. Here are some methods to prevent excessive engine sludge: 1. According to data, fuel has a greater impact on sludge formation than lubricating oil. Therefore, using high-quality fuel is essential. It is recommended that car owners refuel at reputable gas stations, such as Sinopec. 2. In terms of lubricating oil selection, the type of lubricating oil should be determined based on the vehicle's daily usage. It is also important to frequently check the oil level of your car and replenish it as soon as possible when it is low to reduce the pressure on the existing oil.

What Do the Numbers on Car Tires Mean?

Tire data can be categorized into the following types: production date, tire specifications, and whether it is a run-flat tire. It's important to note that all this data is represented by letters or numbers on the tire sidewall. 1. Production date: The four-digit number following DOT indicates the production date. For example, 0712 means the tire was produced in the 7th week of 2012; 1015 means it was produced in the 10th week of 2015. 2. Tire specifications are generally in the following format: (tire width in mm)/(aspect ratio as a percentage of width) R (rim diameter in inches) (load index) (speed rating). For example, 185/60-R17-89H. 3. Whether it is a run-flat tire can usually be determined by the presence of a five-pointed star. However, this is not always accurate, as some brands of run-flat tires may not have the five-pointed star marking.

Why Does the Key Turning Produce a Clicking Sound But Fail to Start the Engine?

The common reasons for hearing a clicking sound when turning the key but failing to start the engine are: 1. The clicking sound is the noise from the relay or the starter motor working, indicating that the starter has responded but lacks the power to turn the flywheel, resulting in failure to start; 2. The battery may be low on charge, which can happen if the headlights were left on when parking or too many external devices were connected; 3. Insufficient voltage can also cause the engine to fail to start with a clicking sound, often due to an old battery that has degraded over time and holds less charge; 4. The gear not being in the P position when starting. It is important to contact a 4S shop promptly to diagnose and fix the specific issue.

What to Do When the Car Tire Pressure Monitoring Light Comes On?

The solution when the car tire pressure monitoring light comes on is: stay calm, do not panic, immediately reduce speed, and avoid sharp steering or sudden braking. Pull over to a safe area, get out of the car to inspect the tires. If low tire pressure is detected and you have a portable inflator, you can measure and inflate each tire. If no equipment is available, drive slowly to the nearest service station or auto repair shop for a tire check. The tire pressure monitoring system works on the principle of gravity balance—if the tire pressure is balanced, it shows normal. If a tire is punctured and loses air, disrupting the balance, the monitoring system will alert you. In this case, pull over to a safe spot and inspect the tire. If a nail or other object is found, do not remove it immediately. Drive to a tire shop or car wash for a patch. If the object is triangular or too large, replace it with the spare tire to avoid the risk of a blowout.

How Long After Window Tinting Can You Roll Down the Windows?

After window tinting, you can roll down the windows within 3 days in summer and 7 days in winter. For a car that has just been tinted, the windows are usually tight, and during the process of opening and closing them, the edges of the window film can easily curl or lift, causing damage to the tint. Here are some precautions after window tinting: 1. Within a week after window tinting, when parking the car, choose a sunny location to ensure that the moisture inside the window film evaporates completely. The micro-water tinting process of V-KOOL window film not only protects the car's dashboard circuits but also ensures better tinting results. 2. Do not wash the car within three days after window tinting to avoid potential film detachment caused by water. Therefore, it is advisable to wash the car before applying the window tint.

Is It Illegal to Install a Rear Wing on a Car?

Installing a rear wing on a car is considered illegal modification. Here are some considerations regarding the installation of a rear wing on a car: 1. If a vehicle owner wishes to change the body color, replace the engine, or alter the body or frame, they must first make the changes and then submit an application for modification registration at the vehicle management office within 10 days. However, according to regulations, the engine and frame cannot be replaced simultaneously, and the vehicle registration information on the driving license must be updated promptly. 2. There are two main methods for installing a rear wing: adhesive mounting and bolt fixing. The former avoids damaging the trunk lid and prevents water leakage, while the latter provides a secure fit but requires drilling holes, which may damage the appearance of the trunk lid and could lead to water leakage if not installed properly. 3. It is recommended that owners avoid making arbitrary modifications and adhere to the original technical specifications. Private modifications of rear wings should be approached with caution, and exaggerated large wings should be carefully considered. Products should be purchased from reputable stores. 4. Rear wings that have not been professionally tested or designed may pose safety hazards during driving. Any vehicle modifications must comply with relevant regulations.
