How often should I change the oil if I don't drive much?

If you don't drive much, you should change the oil every six to eight months, as the oil can oxidize and deteriorate when left in the engine oil pan for extended periods. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts and reduce wear; 2. To carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine; 3. To circulate carbon deposits, sludge, and wear particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. The method for changing the oil is: 1. Lift the vehicle with a jack; 2. Drain the old oil; 3. Remove the oil filter; 4. Install a new oil filter and refill with new oil.

At what level of tire wear must replacement occur?

When tire wear reaches 1.6mm, replacement is mandatory. Factors related to wear level: Tire tread wear level - new tires typically have a thickness of around 8mm. When wear reduces this to approximately 1.6mm, the tire should be replaced. The rate of wear is directly influenced by mileage and driving habits. The normal lifespan ranges between 50,000 to 80,000 kilometers. Upon reaching this mileage, regular checks of tire thickness should be considered. Tread aging degree: Tire aging significantly depends on usage duration and environmental conditions, with a standard service life of about 6 years. Harsh environments can accelerate this timeline. Aged tires will exhibit numerous surface cracks. If such signs are observed, immediate replacement is advised even before reaching 6 years, as delayed action may lead to severe blowout risks.

What lights must be turned on before using fog lights?

Before turning on the fog lights, you need to turn on the parking lights. Fog lights: Generally refers to automotive fog lights, which are installed on the front and rear of the vehicle. They are used for road illumination and safety warnings during rainy or foggy weather, improving visibility for the driver and other road users. Function: Their purpose is to make the vehicle visible to others in conditions of reduced visibility, such as fog or heavy rain. Therefore, fog light sources need to have strong penetration. Most vehicles use halogen fog lights, while LED fog lights are a more advanced option. Fog lights must be installed below the bumper, at the lowest point of the vehicle body, to ensure their effectiveness. If installed too high, the light cannot penetrate the rain or fog to illuminate the road, which can easily lead to dangerous situations.

What is the mileage for a new car's second maintenance?

The second maintenance for a new car is at 5,000 kilometers. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as car servicing. Car maintenance includes the engine system, transmission system, air conditioning system, cooling system, fuel system, and power steering system. Car maintenance involves: 1. Changing the engine oil, oil filter, fuel filter, and air filter; 2. Checking whether the car's coolant level meets the required standards; 3. Checking the brake and clutch fluid levels; 4. Checking whether the power steering fluid reservoir level meets the required standards and inspecting for any oil leaks at the system's pipe connections; 5. Checking the battery fluid level and the windshield washer fluid level.

What is the optimal standard for car tire pressure?

2.3-2.5 bar is the most suitable. Introduction to tire pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Effects of excessive tire pressure: Driving with excessively high tire pressure will reduce the tire's shock absorption effect, thereby increasing the burden on the vehicle's shock absorption system. Over time, it will cause damage to the engine chassis and suspension system. Uneven tire pressure can also easily cause braking deviation, increasing the wear on the suspension system. TPMS (Tire Pressure Monitoring System) can monitor any tire at any time, preventing the above phenomena and reducing the wear on the suspension system.
