How Often Should You Change Your Car's Engine Oil?

How often you should change your car's engine oil depends on the type of oil used. Mineral oil generally needs to be changed every six months or approximately every 5,000 kilometers; semi-synthetic oil should be replaced every 7 to 8 months or around 7,500 kilometers; and fully synthetic oil can last for about one year or 10,000 kilometers. The oil change intervals mentioned are only guidelines, and the actual frequency should be based on your vehicle's driving conditions. If you notice significant engine vibration or increased engine noise, you may consider changing the oil earlier. Engine oil is the lubricant used in engines, composed of base oil and additives. It serves multiple functions, including lubrication and wear reduction, aiding in cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption.

What is ESP?

ESP stands for Electronic Stability Program, which is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. It analyzes vehicle driving state information from various sensors and then issues correction commands to ABS (Anti-lock Braking System) and ASR (Acceleration Slip Regulation) to help maintain dynamic balance. The ESP system consists of a control unit and components such as steering sensors (monitoring the steering angle of the steering wheel), wheel sensors (monitoring the speed of each wheel), yaw sensors (monitoring the vehicle's rotation around the vertical axis), and lateral acceleration sensors (monitoring centrifugal force during turns).

Where is the manufacturing year of a car tire located?

The manufacturing year of a car tire is printed on the tire sidewall near the rim, represented by 4 digits. The first two digits indicate the production week, and the last two digits indicate the production year. How to check the tire manufacturing year: There is usually a DOT mark embossed on one side of the tire. The last four digits after this mark indicate the production date information, consisting of four digits "AABB". The first two digits "AA" represent the week of the year, while the last two digits "BB" represent the year. Precautions for car tires: Tires with cracks should be replaced immediately. If the crack length is less than 6mm and hasn't damaged the internal cord material, it can be repaired at a shop without immediate replacement. However, if the damage is too large or the sidewall is already broken, the tire should be replaced as soon as possible. If you feel it's wasteful to discard the replaced tire, it can be repaired and used temporarily as a spare tire. The four tires of a family car are generally of the same brand and specification to ensure optimal vehicle performance. If the four tires have inconsistent sizes, structures, or wear patterns, it will affect the vehicle's handling and stability. Therefore, when tires show significant wear and one needs replacement, it's best to replace all four tires simultaneously.

What Causes Car Body Vibration After Ignition?

The severe vibration of a car engine can be caused by aging or loosening of engine mounts, carbon buildup issues, or fuel system malfunctions. Ignition System Malfunction: Problems in the ignition system, such as faults in the car's ignition system, can lead to poor ignition system performance and inadequate spark plug firing, resulting in unstable engine operation during idle. Aging of Engine Mounts: Aging or loosening of engine mounts, which are rubber blocks placed between the engine and the car frame, can cause severe engine vibration. These mounts are designed to reduce engine vibration and provide cushioning during operation, as well as to secure the engine in place. Once the engine mounts age or loosen, the engine's vibration becomes significantly worse. Carbon Buildup Issues: Carbon deposits, including those in the cylinders, throttle body, spark plugs, and intake manifold, can affect the engine's performance. Excessive carbon buildup inside the engine can impact ignition energy, air intake efficiency, and the air-fuel mixture ratio, leading to unstable power output and causing vibrations during idle and acceleration. Poor Fuel Quality: In many cases in China, unstable engine operation, such as "idle" vibration, is closely related to fuel quality. Poor fuel quality can damage engine performance, leading to idle vibration issues.

How Long Can a Car Spare Tire Last?

Car spare tires are divided into full-size spare tires and compact spare tires. Full-size spare tires can be used continuously without any issues, while compact spare tires should not exceed a speed of 60 kilometers per hour and can be driven for up to 100 kilometers. They are not suitable for long-term use. It is important to regularly inspect the spare tire to avoid discovering it is unusable when an emergency arises. Tires are circular elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. Car tires are one of the essential components of a vehicle, directly contacting the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort, smooth driving, and strong adhesion between the wheels and the road.

Do Cars No Longer Have a Break-in Period?

Nowadays, cars still have a break-in period, which typically ranges from 1,000 to 1,500 kilometers. The break-in period refers to the initial driving phase of a new car or one that has undergone major repairs, serving as the essential mileage for ensuring full contact, friction, adaptation, and stabilization of mechanical components. Vehicles in the break-in period should minimize load, as greater loads increase driving resistance and demand higher driving force from the engine, thereby increasing engine stress. During the break-in period, it's important to warm up the car before driving, and this practice should continue even after the break-in period. Warming up a car requires technique: generally, idling to warm up is not recommended. After normal startup, simply avoid aggressive acceleration and maintain low engine RPMs while driving. Typically, warming up can be completed within three minutes.
