How Often Should You Change Oil If You Drive Less?

For vehicles driven less frequently, change the engine oil every six months or 5,000 kilometers. Full synthetic oil can be changed annually. Below are the reasons for regular oil changes: 1. Engine oil contains various additives such as anti-oxidation/corrosion agents, anti-wear agents, and detergent dispersants. After the expiration date, these additives gradually lose effectiveness, significantly reducing the oil's performance. This makes it unable to handle the engine's high-load, high-speed extreme operations, accelerating vehicle wear. 2. The primary functions of engine oil are lubrication, cleaning, and heat dissipation. Oil deterioration has a specific timeline: "conventional" oil typically begins oxidizing after about 3 months of exposure to air ("semi-synthetic" around 6 months, "full synthetic" approximately 9 months). Reduced functionality fails to provide proper engine lubrication, cleaning, and cooling, potentially damaging automotive components.

What Causes the Steering Wheel Light to Illuminate?

The illumination of the steering wheel light indicates an issue with the vehicle's power steering system. Possible causes include: 1. Excessive air in the power steering system, leading to abnormal steering. 2. Foreign objects in the steering hydraulic lines causing the steering pump flow control valve to stick. 3. Loose connections in the power steering system, resulting in steering fluid leakage. 4. Excessive wear of the steering gear piston cylinder, poor oil seal performance, or control valve adhesion/damage. Solutions: Inspect the steering gear, steering pump control valve, oil reservoir filter, and steering fluid; clean the entire power steering system; check tire pressure and refill if low; tighten all connection bolts for oil pipes; replace oil pipes, power steering pump, or power steering gear as needed.

How to Identify Tire Tread Patterns

Tire tread patterns are typically located on the sidewall of the tire. Please check the sidewall for details. Below is relevant information about tire tread patterns: 1. Longitudinal tread patterns are arranged along the circumference of the tire. A tire usually has several of these, though they are not commonly seen in everyday use. 2. Compared to longitudinal patterns, transverse tread patterns are longitudinally discontinuous but laterally continuous. This design provides the tire with greater lateral stiffness, excellent friction, and braking performance. Tires with this tread pattern are widely used in specialized fields, such as agricultural machinery like harvesters and tractors. 3. Block tread pattern tires are widely used in off-road vehicles. They are divided into three types: highway tires, all-terrain tires, and mud tires. 4. Unidirectional tread patterns have interconnected grooves, offering strong road performance and drainage capability. These tires have a fixed rolling direction. 5. Mixed tread patterns combine the quick-draining longitudinal patterns in the center with the lateral patterns on the shoulders that provide grip, creating an ideal scenario. Currently, this mixed tread is widely used in most vehicles, including cars, buses, and trucks.

What Does Normal Car Maintenance Include?

The following are the parts that need maintenance in a normal car: 1. Engine oil. Engine oil is the most routine maintenance. If the oil is not changed for a long time, the vehicle may feel sluggish when accelerating. Changing the oil usually resolves this issue. 2. The three filters, including the oil filter, air filter, and fuel filter. The oil filter must be changed whenever the oil is changed. If only the oil is changed without replacing the oil filter, it would be the same as not changing the oil at all because the filter is dirty. The air filter is generally replaced every 20,000 kilometers. The fuel filter is replaced every 40,000 kilometers. The cabin air filter should be replaced once a year. 3. Engine. Use the appropriate grade of engine oil and replace it and the filter regularly (every 5,000 kilometers); frequently maintain the air filter and replace it periodically (every 20,000 kilometers); regularly clean the fuel system and replace the fuel filter (every 30,000 kilometers); maintain the radiator cooling net periodically (every 30,000 kilometers); replace the spark plugs regularly (every 40,000 kilometers or based on driving conditions). The most important part of car maintenance is changing the engine oil and oil filter. The most frequent task in car maintenance is washing the car. The parts that need the most frequent checks are the tire surface and pressure, oil level, coolant level, and brake fluid level.

What Are the Common Problems with Power Windows?

Here are some common issues related to power windows: 1. Unusual noises from the window when driving on bumpy roads. Possible causes include loose screws or clips, foreign objects inside the door panel, or excessive clearance between the glass and the sealing strip. To fix such minor issues, simply remove the foreign objects, secure the glass, tighten the screws, or replace the inner seal. 2. Unusual noises during window operation. One possible cause is noise from the power window guide rail, which can be resolved by cleaning the rail and applying some lubricant. If the problem persists, it may indicate a faulty power window component, requiring replacement of the entire power window assembly. It is recommended to visit a reputable repair shop or authorized 4S dealership for this service. 3. Difficulty in operating the window. One reason could be aging or deformed window seals, which create resistance during operation. In such cases, replacing the seals is necessary. If the issue is minor, applying talcum powder for lubrication can provide a temporary solution. Another reason could be dirty or obstructed window guide rails, often caused by items like business cards being inserted into the window slot. Cleaning the rails and removing any obstructions is required. Additionally, a faulty motor or low battery power may also cause this issue, necessitating recharging or motor replacement. 4. The window automatically lowers after being raised halfway. This could be due to problems with the sealing strip or the power window mechanism. Vehicles equipped with anti-pinch protection for windows often encounter such issues. If this problem occurs within three years of vehicle ownership, it is likely due to a faulty power window mechanism.

How to Prevent Fogging on Rearview Mirrors?

To defog rearview mirrors, you can activate the rearview mirror heating function. Below are detailed instructions on how the rearview mirror heating function works: 1. Function: When the button is pressed, the electric heating elements behind the rearview mirror glass will quickly heat up to a set temperature within a few minutes, typically between 35-60 degrees Celsius. Warm air will emerge from both left and right rearview mirrors, while water droplets on the mirror surface will gradually evaporate and shrink due to the rising temperature. The fog will slowly dissipate, achieving the effect of heating the mirror, removing fog and frost. 2. Usage While Engine is Running: When using the rearview mirror heating function, ensure the vehicle is in an active state. Avoid using this function when the car is cold. If the battery is low on charge or malfunctioning, the rearview mirror heating may not activate. 3. Duration of Use: Each use should not exceed 30 minutes, as prolonged usage may affect the mirror's lifespan and clarity.
