What are the Five Oils, Four Filters, and Three Fluids in a Car?

Here is a detailed introduction to the five oils, four filters, and three fluids in a car: 1. Five oils: Refers to five types of fluids—gasoline, engine oil, transmission fluid, brake fluid, and power steering fluid. 2. Four filters: Oil filter, air filter, cabin air filter, and fuel filter. 3. Three fluids: Windshield washer fluid, coolant, and battery fluid. Below is an extended introduction to car maintenance items: 1. Engine oil and oil filter replacement: Primarily pertains to the lubrication system's maintenance. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove impurities from the engine oil, ensuring the lubrication system operates normally. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car requires maintenance every 5,000 kilometers. 2. Filter replacement: The air filter's function is to filter air before it enters the cylinders, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is typically replaced after driving 20,000–25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, battery, throttle body, fuel injectors, and brake pads are all part of the inspection items during routine maintenance, with maintenance performed as needed based on usage conditions.

Is it okay to service the car only after 10,000 kilometers?

According to the regulations of different car manufacturers, servicing the car only after 10,000 kilometers may have certain impacts. This means exceeding the first service interval, which could lead to a decline in the lubricating performance of the engine oil, thereby increasing engine wear and potentially causing louder engine noise during operation. Therefore, it is recommended that car owners adhere to the first service interval for vehicle maintenance. The first service, also known as the initial maintenance, is generally performed after using a new car for 3 months or driving 5,000 kilometers (however, the interval may vary depending on the car model, and the car manual clearly specifies the first service mileage). After that, the car needs to be serviced based on whichever comes first—time or mileage. For example, if the car hasn't been used for 3 months but has already reached 5,000 kilometers, it should be taken to a 4S shop for maintenance promptly. In addition, routine car maintenance is divided into minor and major services. Generally, for household cars, the minor service interval is 3 months or 5,000 kilometers, while the major service interval is 40,000 kilometers. A minor service typically refers to the routine maintenance performed after the car has traveled a certain distance or within the manufacturer's specified time to ensure vehicle performance. It mainly includes changing the engine oil and oil filter. A major service refers to the routine maintenance performed at the manufacturer's specified time or mileage, which includes replacing the engine oil, oil filter, air filter, and fuel filter. If the car is serviced only after 10,000 kilometers, the following maintenance items should be performed: Replace engine oil and oil filter: The engine oil needs to be changed at 10,000 kilometers. Since engine oil lubricates the car during operation, its performance may degrade or even fail over time. It should be replaced during maintenance to prevent abnormal engine wear. Car inspection: After driving 10,000 kilometers, the car's engine, transmission, air conditioning system, steering system, braking system, suspension, body, tires, and other aspects should be inspected to ensure performance during operation. Clean or replace air and cabin air filters: After 10,000 kilometers, it is recommended to clean the air and cabin air filters. If the daily driving environment is harsh, these filters can be replaced after 10,000 kilometers to ensure better driving safety. These parts can be replaced by the owner, but if unsure, a professional can handle it. Check various car fluids: After 10,000 kilometers, check the coolant, brake fluid, tire pressure, etc. Abnormal fluid levels during operation may lead to abnormal wear and affect car performance.

What does idle speed mean?

Idle speed refers to the operation of the engine under no-load conditions, where it only needs to overcome the frictional resistance of its internal components without delivering power externally. This low rotational speed that maintains stable engine operation is called idle speed. Idle speed is one of the five fundamental operating conditions of an engine, providing convenience for drivers in various situations such as driving and temporary parking. For example, when waiting at a red light, it prevents the engine from stalling while also contributing to energy saving and emission reduction. However, prolonged idling can lead to carbon buildup in the vehicle. If the accelerator pedal is completely released, the engine enters idle speed. When adjusting the idle speed, the rotational speed should not fluctuate abruptly, as this can cause premature wear to the engine. It is recommended to have the idle speed adjusted at an automotive repair facility.

How to Determine When a Car Battery Needs Replacement

Methods to determine when a car battery needs replacement: 1. The car battery shows obvious swelling, deformation, or bulging; 2. The car is particularly difficult to start, and charging has no effect, indicating the battery life is exhausted; 3. Check the observation hole of the car battery—the normal state is green. If it is any other color, it means the battery life has expired. If the battery is well-maintained and good usage habits are followed, the battery life can be extended to some extent. When the electrolyte inside the battery is insufficient, it will cause the battery to lose charge, requiring timely refilling. After turning off the car, ensure all lights and electrical devices are switched off to avoid excessive battery drain leading to power loss. If the car is parked for an extended period, it is recommended to disconnect the battery's negative terminal to cut off power, which can prevent power loss.

What does it mean when the EPC light is on in the car?

The EPC indicator light can illuminate in two scenarios: during the power-on self-test and under other circumstances. The power-on self-test is a pre-driving check of all vehicle sensors. Typically, if the engine is not started after power-on, the light will turn off by itself after about 3 seconds. If the EPC light remains on after starting the vehicle or illuminates under other conditions, the possible causes include faults in the engine intake system, throttle body, fuel system, engine, ECU control unit, or brake lights. Below is a detailed explanation of the reasons for the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will activate if the engine intake is obstructed or insufficient. Throttle body fault: Carbon buildup is a common issue with the throttle body. Additionally, dirt accumulation can affect intake, triggering the indicator light. Fuel system fault: Issues such as substandard fuel, deteriorated fuel, or poor fuel atomization can cause the light to illuminate. Engine fault: Insufficient engine pressure or problems with components like the intake valves can also prompt the EPC light. ECU control unit fault: Interference with the vehicle's computer signals or false alarms from the computer may trigger the light. Brake light fault: Malfunctions like non-functioning brake lights, faulty brake switches, or brake circuit issues can cause the EPC light to illuminate. Solutions for when the EPC light is on: Troubleshoot intake system issues, use fuel with the appropriate octane rating, and clean the throttle body. Remove carbon deposits from relevant components. Re-flash the ECU with updated data. If the EPC light comes on, the driver can first try turning off the engine and restarting it to see if the light remains illuminated. If it does not, the issue may have been a temporary glitch. If the light stays on or frequently illuminates, the vehicle should be taken to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data deviates from normal values, the EPC system takes predefined actions to regulate the powertrain. Common EPC indicator lights come in two colors: yellow and red. A yellow EPC fault light indicates that the vehicle can still be driven, but it should be taken to a repair facility at a reduced speed. A red EPC fault light signifies a more serious issue, and the driver should pull over immediately and contact a repair professional. Continuing to drive with a red EPC light can damage core components or compromise safety.
