oilservice is not a fault warning light, but a maintenance reminder light. When this light illuminates, it indicates that the vehicle requires maintenance. Here is relevant information: Maintenance timing: Automotive maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of the vehicle. Different vehicle models from various manufacturers have different scheduled maintenance intervals, which should be determined according to the vehicle's user manual. Maintenance content: Regular vehicle maintenance is crucial for the vehicle's lifespan and the safety of drivers and passengers. Engine oil serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and improve any shortcomings in the base oil's performance, providing certain new characteristics, making them an essential part of lubricants.

When I saw the 'oil service' light illuminate on the dashboard, I immediately knew it wasn't a malfunction signal but rather my vehicle reminding me that an oil change is due. I recall the technician at the 4S dealership mentioning last time that this light is part of the car's built-in maintenance reminder system, primarily activated based on mileage or time calculations. For regular vehicles, engine oil should be replaced every 5,000 to 10,000 kilometers to ensure proper engine lubrication and efficient heat dissipation. Ignoring it could lead to aged oil thickening or contaminant buildup, increasing engine friction which may cause overheating or even cylinder scoring – repairs for which can be costly. I'd recommend first checking the dipstick to see if the oil level is too low or if the color has turned black, then scheduling a comprehensive service at an authorized maintenance center. Timely oil changes also extend engine lifespan and improve fuel efficiency, costing just a few hundred dollars annually – a worthwhile investment.

How to Operate the Steering Wheel to Control Car Direction?

Here are the correct methods for operating the steering wheel to control the car's direction: 1. Make full use of a reference point on the front of the car. When the reference point is in the middle or on one side of the road, you should accurately sense the vehicle's position to determine the timing and extent of steering or correcting the wheel. 2. Utilize your peripheral vision effectively to avoid the phenomenon of correcting the direction too late due to focusing only on distant objects. 3. Develop a good habit of not moving the steering wheel unless the car's front is deviating. When correcting direction, ensure it is "timely" and moderate in extent. Generally, returning to the straight position should be slightly early and with minimal adjustment. 4. Combine with field training to practice the timing and speed of steering, such as in figure-8, S-shaped, and right-angle turns. 5. When driving on the right side, to prevent the car's front from veering to the right, turn the steering wheel to the left until there is no free play, allowing your left hand to sense the vehicle's current position.

Why does the vehicle shake when starting?

There are several main reasons: 1. Incorrect air-fuel ratio: The air-fuel ratio is not accurately adjusted, which occurs in both open-loop and closed-loop control. In a closed-loop control environment, the minimum operating temperature of the car's oxygen sensor is 370 degrees Celsius. However, when the vehicle is just started, the exhaust pipe temperature does not reach 370 degrees Celsius, and the oxygen sensor does not start working. At this time, the ECU makes a misjudgment, leading to errors in controlling the ignition timing through the actuator, thereby reducing power output and causing the vehicle to shake. 2. Carbon deposits on the engine valves and intake passages: Carbon deposits absorb fuel. Even if the remaining fuel burns completely, it cannot achieve the required power, making shaking inevitable. 3. Different working conditions of each cylinder: After long-term use, the spark plugs of a multi-cylinder engine may have different ignition control and timing gaps. However, the EDC cannot detect this error, leading to a deviation between theory and practice. Some cylinders may have lower efficiency, causing the vehicle to shake. 4. Failure of the coolant temperature sensor: The coolant temperature sensor is one of the important bases for the computer to judge the real-time working condition of the car engine. During a cold start, the engine temperature is low, but if the coolant temperature sensor misjudges and sends an excessively high signal to the computer, the computer will inject too much fuel. The fuel quantity is smaller than normal, and shaking is inevitable.

Reasons for Abnormal Noise in the Coolant Reservoir?

The vehicle's cooling system has malfunctioned. Below is an introduction to the vehicle's cooling system: 1. Introduction: The main function of the cooling system is to dissipate heat into the air to prevent engine overheating, but the cooling system also has other important roles. The engine in a car operates best at an appropriately high temperature. If the engine becomes too cold, it accelerates component wear, reducing engine efficiency and increasing pollutant emissions. Therefore, another key role of the cooling system is to quickly warm up the engine and maintain it at a constant temperature. 2. Common Issues: Engine Overheating: Air Bubbles: Air in the coolant can create many bubbles when agitated by the water pump, which can hinder heat dissipation from the water jacket walls. Scale: Calcium and magnesium ions in water can gradually form scale at certain high temperatures, significantly reducing heat dissipation capacity and partially blocking water passages and pipes, preventing normal coolant flow. Hazards: Engine components expand due to heat, disrupting normal clearance fits, affecting cylinder air intake, reducing power, and diminishing the lubricating effect of engine oil. Corrosion and Leakage: Ethylene glycol has strong corrosive properties on the radiator. As the corrosion inhibitors in the coolant degrade, they can corrode components such as the radiator, water jacket, water pump, and pipes.

How to Use Car Air Conditioning Correctly?

The correct methods for using car air conditioning are as follows: 1. When using the car air conditioning, never open the car windows, as this will increase the load on the air conditioning and cause its power consumption to rise sharply. 2. If you find that your car air conditioning seems ineffective during use, it indicates a problem with the air conditioning system. You should immediately turn off the air conditioning to prevent further damage and take the car to a repair shop. 3. Different car models have different methods for turning on the air conditioning. If your car does not have an automatic speed control device, you should not turn on the air conditioning system first. The correct method is to start the engine before turning on the air conditioning. 4. For automatic transmission cars, you should not turn on the air conditioning when driving at speeds of 120 km/h. Similarly, for manual transmission cars, avoid using the air conditioning at 110 km/h. This reduces the workload on the air conditioning and helps prolong its lifespan. 5. It's important to match the air conditioning's fan speed with the car's requirements. Also, pay attention to temperature control—avoid keeping the temperature at the lowest setting for extended periods, as this can damage the air conditioning chip. 6. In summer, monitor the car engine's condition when using the air conditioning. If the engine has been running for too long and overheats, turn off the air conditioning immediately to avoid affecting both driving performance and the air conditioning system. 7. Avoid using the car air conditioning when driving on dusty roads to prevent dust from entering the system. If necessary, set the air intake to the recirculation mode to block outside dust. 8. After using the air conditioning for an hour while driving, open the windows for at least 10 minutes to ventilate the car. This prevents the buildup of carbon monoxide, which can harm health and driving safety.
