Is 4 Liters of Engine Oil Enough for One Maintenance?

4 liters of engine oil is generally sufficient for one maintenance session for vehicles such as the Volkswagen Golf, Bora, Toyota Corolla, etc. However, there are cases where 4 liters may not be enough, such as for the Audi A5 and Volkswagen Touran, which require approximately 5 liters of oil during maintenance. The exact amount of oil needed depends on the specific vehicle model, and some models may require different amounts of oil based on their engine displacement. Below is some additional information: 1. Introduction and Function: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the "blood" of a car. 2. Composition and Function: Engine oil consists of two main components: base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives are used to compensate for and improve any deficiencies in the base oil's performance, as well as to provide additional beneficial properties. Additives are an essential part of engine oil.

Is the Emission Malfunction Light a Serious Issue?

Emission malfunction light is not a serious issue, and you can continue driving. Below are the reasons why the emission malfunction light may illuminate: 1. Due to substandard fuel quality, causing incomplete combustion of the engine's air-fuel mixture. Try to avoid refueling at small gas stations. After refueling, you can add some high-quality fuel additives to improve fuel quality. 2. If the exhaust emission light stays on, check for any faults in the engine. Problems with all sensors related to the air-fuel mixture combustion in the engine, engine wiring, engine actuator motors, solenoid valves, or the control unit can cause the engine exhaust emission malfunction light to illuminate. Additional Information: The main function of the engine exhaust emission warning light is to monitor the state of the engine's air-fuel mixture through the oxygen sensor. When the air-fuel mixture changes, leading to excessive exhaust emissions, the control unit will record the fault and store it, thereby illuminating this warning light to alert the driver.

How many years can the Ora Black Cat be driven?

Great Wall Ora Black Cat typically offers a warranty period of 8 years or around 150,000 kilometers for the three key electric components (battery, electric drive, and electric control). Introduction to the Black Cat model: As a pure electric vehicle under the Great Wall Ora brand, the Ora Black Cat currently holds a significant position in the sales composition of the Ora brand. From sales data, the Ora Black Cat can be regarded as the undisputed sales leader or pillar model of the Ora brand. After-sales service: The Ora Black Cat provides a whole vehicle three-guarantee period of 2 years/50,000 kilometers, a whole vehicle repair warranty of 3 years/120,000 kilometers, and a warranty for the power battery pack assembly, drive motor, and motor controller of 8 years/150,000 kilometers. For all three, whichever comes first in terms of time or mileage applies.

How to Determine if a Thrust Bearing is Faulty?

Here are the methods to determine if a car's thrust bearing is broken: abnormal noise when turning the steering wheel, vehicle deviation from the intended direction, increased tire noise during driving, and the steering wheel becoming heavier. Here are the reasons for thrust bearing damage: 1. The ball thrust bearing cannot withstand horizontal forces. When turning the steering wheel while stationary, the ground exerts a horizontal torque on the tire, which is the cause of the 'clunk' sound. 2. Insufficient bearing quality. 3. The hardness of the surface treatment does not meet the required standards. Additional information: The thrust bearing, also known as the pressure bearing, is located between the spring at the top of the shock absorber and the rubber at the top of the shock absorber. It consists of steel balls, a shaft ring, and a seat ring, and is an important component of the car's shock absorber system.

What is the Difference Between On-Demand 4WD and Full-Time 4WD?

Here are the differences between on-demand 4WD and full-time 4WD: 1. Different structures: On-demand 4WD has a relatively simple structure; full-time 4WD has a more complex structure. 2. Different power distribution between front and rear axles: On-demand 4WD has a smaller adjustment range; full-time 4WD has a larger adjustment range. 3. Different central differentials: On-demand 4WD responds more slowly; full-time 4WD responds faster. 4. Different operation methods: On-demand 4WD has no separate button in the vehicle; full-time 4WD has a separate button. Additional information: Part-time 4WD vehicles are designed with a transfer case device, which may be a transfer case lever, an electronic button, or a knob. Most on-demand 4WD systems have a separate button in the vehicle marked with "lock," while some are automatically engaged without any button in the vehicle.

Is There a Difference Between Factory Paint and Repainted Car Paint?

Both factory paint and repainted car paint can meet the decorative and anti-corrosion requirements of the vehicle's surface. However, their application methods differ significantly. Factory paint is applied using robotic automation, ensuring consistent viscosity and high-quality finish. In contrast, repainting is done manually, often in suboptimal conditions. The most notable difference is that repainted areas lack the electrocoat layer, consisting only of the color coat and clear coat. This often leads to issues like color mismatch and accelerated paint aging. The impact of repainting includes: 1. Effect on Used Car Value: Used car inspectors typically use paint thickness gauges. Abnormal readings indicate repainted areas, which can reduce the vehicle's resale value by 20,000 to 30,000 yuan, depending on the situation. 2. Damage to the Original Paint's Phosphating and Electrocoat Layers: These layers protect the metal substrate from corrosion. Standard repainting cannot restore them, leading to rust formation over time. Additionally, no matter how skilled the repainting job, color discrepancies and paint aging will eventually become apparent.
