Generally, the engine oil change interval is between 5,000 to 10,000 kilometers or every six months to a year. The recommended maintenance schedule can be found in the warranty certificate that comes with the car purchase. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. Below is an introduction to engine oil-related information: 1. There are 4 types of summer oils, 6 types of winter oils, and 16 types of all-season oils. The summer oil grades are: 20, 30, 40, 50, 60. The larger the number, the higher the viscosity and the higher the maximum applicable temperature. 2. The winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W. The letter 'W' stands for Winter. The smaller the number before 'W', the lower the viscosity at low temperatures, the better the low-temperature fluidity, and the lower the minimum applicable temperature.

I just bought a new car last year and was initially confused about oil changes. After consulting a friend at the 4S店 and checking the user manual, I now know that new cars usually get their first free oil change between 3,000 to 5,000 kilometers. After that, it's generally every 6 months or every 5,000 to 10,000 kilometers. The key is your driving habits and environment: if you often drive on highways or in congested city traffic, use fully synthetic oil, which can extend the interval to around 7,500 kilometers. On the other hand, if you frequently make short trips with constant starts and stops or drive in dusty areas, you should check more often and change it earlier. I make it a habit to check the oil dipstick’s color and level every month—don’t wait for the warning light to come on. Proper maintenance for a new car can extend the engine’s lifespan and make driving smoother. Don’t listen to inexperienced people giving misguided advice.

Having driven for over 20 years, I've developed my own rhythm for new car oil changes. After the first maintenance, changing every 5,000 to 8,000 kilometers or every six months is relatively safe, but modern vehicles using synthetic oil can appropriately extend this interval. Don't blindly follow old traditions; during high-speed cruising, the engine runs smoothly, making 7,500 kilometers no problem. In city stop-and-go traffic, oil contamination happens faster, so it's best to change it promptly. I recommend new car owners to carefully read the manual, which contains specific data as different models have varying requirements. Changing oil too frequently is a waste of money and can lead to oil sludge buildup, affecting performance. Regularly visit professional shops for oil quality checks to ensure no leaks and minimal dust, keeping the engine healthy and as good as new for ten years.

As an environmentally conscious individual, I pay close attention to the eco-friendly aspects of engine oil changes for new cars. It is recommended to use high-performance synthetic oil, which can support extended oil change intervals of up to 1 year or 15,000 kilometers, reducing waste oil emissions. Most modern vehicles are equipped with intelligent monitoring systems that dynamically provide prompts based on driving data, which is more precise and resource-efficient than fixed intervals. Remember that high temperatures and pressure accelerate oil degradation, and extra dust in rural areas may require earlier attention. Maintaining smooth driving with fewer sudden accelerations helps preserve oil quality and extend its lifespan. Tracking maintenance records through apps saves time and conserves energy for the planet. Proper maintenance makes your car cleaner and more eco-friendly.

How Does Vehicle Anti-Skid System Work?

Vehicle anti-skid system works as follows: The ABS electronic control unit receives signals from the wheel speed sensors, calculates and analyzes to determine the wheel slip rate and vehicle speed. The electronic control unit then regulates the wheel slip rate by controlling throttle opening and brake pressure to prevent skidding during driving. In vehicles equipped with anti-skid systems, the system is automatically activated when powered on. It primarily analyzes information from sensors to maintain optimal dynamic balance during operation. The anti-skid system enhances vehicle stability, particularly evident during oversteering or understeering conditions.

What does DSP mean in a car?

DSP in a car stands for Digital Signal Processor. DSP is the abbreviation of Digital Signal Processing in English, which translates to digital signal processing in Chinese. The function of DSP is to control frequency response, achieving certain processing and modification effects on audio signals. For example, when listening to music, there are different options such as bass, pop, rock, blues, etc. After selecting one, the tone and sound of the song will change. Digital signal processing utilizes digital processing, through computers or more specialized digital signal processors, to perform various signal processing operations. Signals processed in this manner are represented as a series of numbers that sample continuous variables in the time domain, spatial domain, or frequency domain.

How Often Should Dual Clutch Fluid Be Changed?

Dual clutch fluid should be changed for the first time after 3 years or 60,000 kilometers, and subsequently every 2 years or 40,000 kilometers. It is essential to use the manufacturer's specialized fluid for replacement. Changing the transmission fluid is the most critical aspect of transmission maintenance, and it should be performed according to the manufacturer's maintenance manual. Regularly inspect the condition of the transmission fluid; if it turns black or becomes cloudy, it should be replaced promptly. Prolonged neglect of fluid changes can accelerate wear, potentially damaging the transmission gears and increasing resistance. The dual clutch, or Dual Clutch Transmission (DCT), differs from conventional automatic transmission systems. It combines the characteristics of both manual and automatic transmissions, offering the flexibility of a manual transmission and the comfort of an automatic transmission while providing uninterrupted power output.

Which button is used to spray windshield washer fluid?

To spray windshield washer fluid, press the windshield wiper switch button. Windshield washer fluid is primarily composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. It serves multiple functions including cleaning, antifreeze, antifog, antistatic, lubrication, and corrosion prevention. The steps to add windshield washer fluid are: 1. Open the front hood and locate the windshield washer fluid reservoir; 2. Open the packaging of solid windshield washer fluid and place it into the reservoir; 3. Add clean water until the reservoir is full; 4. Wait for the solid windshield washer fluid to completely dissolve. Precautions for using windshield washer fluid include: 1. Spray intermittently, do not spray continuously; 2. Avoid filling the reservoir to the very top.
