Is There a Problem If a Car Hasn't Had Its Oil Changed for a Year and a Half?

It is problematic if a car hasn't had its oil changed for a year and a half, as the oil will deteriorate and lose effectiveness, providing no protection to the engine. The functions of engine oil: Engine oil lubricates and reduces friction, aids in cooling, seals against leaks, prevents rust and corrosion, and acts as a shock absorber for the engine. Regular oil changes are essential: Depending on the type of oil, fully synthetic oil typically needs to be changed every 10,000 kilometers, semi-synthetic oil every 7,500 kilometers, and mineral oil every 5,000 kilometers. Even if the mileage hasn't been reached, the oil must be changed after one year because, even if unused inside the engine, oil loses most of its functionality after a year.

Can the exterior of a car radiator be washed with water?

Car radiator exteriors can be washed with water. Below is an introduction to the cleaning methods and intervals for radiator exteriors. Cleaning methods for radiator exteriors: The correct cleaning method involves removing the radiator for washing. Separate the radiator and condenser, then use a brush or high-pressure water gun to remove dirt from the gaps. Rinse the surface with clean water, but be careful not to damage the aluminum fins or pipes. Aluminum fins are easily deformed and can be damaged with excessive force. Too many damaged fins will lead to poor heat dissipation, and damaged pipes on the radiator can cause coolant leaks. Cleaning intervals for radiator exteriors: It is recommended to clean the exterior of a car radiator every six months. Since it contains coolant, which prevents the cooling system from freezing in low temperatures and boiling in high temperatures, impurities and sediment can accumulate during use, affecting heat dissipation efficiency. Therefore, regular cleaning is necessary.

What Are the Reasons for a Mercedes-Benz Suddenly Not Accelerating When the Gas Pedal is Pressed?

It is related to the working condition of the engine ignition system and the electronic fuel injection system. The following are the specific reasons and solutions: 1. Abnormal ignition system: The ignition energy is too weak or there is intermittent misfiring. Solution: Replace with better-performing spark plugs. 2. Abnormal electronic fuel injection system: Low fuel pressure, clogged fuel filter, clogged or leaking fuel injectors causing poor fuel spray and atomization. Also, check if the air filter is severely clogged, as this can lead to insufficient air intake, resulting in an overly rich air-fuel mixture. Solution: Take it to a specialized repair shop for inspection and analysis. 3. Low cylinder pressure or clogged exhaust system: Solution: Take it to a specialized repair shop for inspection and analysis.

What to Do When the Central Locking System Keeps Making Abnormal Noises?

Central locking system continuously making abnormal noises may indicate a malfunction. Here are the solutions: 1. Lock Body Issue: Go to an auto repair shop to replace the lock body. 2. Anti-Theft Device Issue: You can adjust the sensitivity of the anti-theft device on its control box. Generally, the control box is installed under the dashboard. After opening it, you will see a screw knob that can be rotated to adjust the sensitivity. It is recommended to reduce the sensitivity to a level where kicking the tire does not trigger the alarm. 3. Motor Issue: An aged motor needs replacement. 4. Fuse Issue: A blown fuse in the switch circuit needs replacement. 5. Central Locking System Host Issue: A faulty central locking system host needs replacement. 6. Main Motor Linkage Rod Issue: A loose main motor linkage rod needs tightening.

What to Do If a Small Piece Is Scratched Off the Side of the Tire?

Tire sidewall scratched off a small piece needs to check whether the gap has been damaged or affected the tire material. If the sidewall is already damaged, it should be replaced in time; but if the gap has not affected the car tire material, it can continue to be used. Precautions to note when a small piece is scratched off the side of the tire: 1. If you find that a small piece is scratched off the side of the car tire, you should carefully inspect it. 2. Tire wear may interfere with the driver's normal driving and even put them in a potentially hazardous situation. 3. Tires are often used under complex and harsh conditions, bearing various deformations, loads, forces, and high and low-temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. 4. Drivers should pay great attention to the protection of car tires during driving and deal with tire failures in a timely manner.

Is It Normal for Car LED Lights to Get Very Hot When in Use?

If the temperature exceeds 60 degrees Celsius, it is abnormal and indicates a heat dissipation issue. Below this temperature, it is considered normal. Introduction to the Heating Principle of Car LED Lights: Car LED lights use light-emitting diodes as the light source. During operation, only 25% of the electrical energy is converted into light energy, while the remaining electrical energy is entirely transformed into heat energy. When accumulated in an enclosed space, the heat builds up, causing the LED lights to become increasingly hot. Therefore, car LED lights must be used in conjunction with heat dissipation devices. Causes and Solutions for Overheating of Car LED Lights: If an infrared thermometer detects that the temperature of the headlight cover exceeds 60 degrees, it indicates that the LED lights are overheating due to poor heat dissipation in the lighting system. This issue can be resolved by spraying nano-radiation coating on the surface of the light body to enhance its heat radiation capability or by installing additional fans.
