C3 is a standard for engine oil, specifically a European standard. C3 engine oil contains DPF and WC. Domestic vehicles in China cannot use C3 engine oil because it is formulated for the fuel quality and road conditions in certain European countries and regions, making it unsuitable for use in China. Engine oil is often referred to as the lifeblood of the engine, as it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat within the engine. Without engine oil, the engine cannot function properly. It is recommended that car owners regularly change their engine oil during routine vehicle maintenance and replace the oil filter each time the oil is changed.

What tires are used on the Volkswagen Tiguan?

There are three original equipment tires for the Volkswagen Tiguan: Michelin Primacy-LC Bo Yue, Hankook Dynapro-HP, and Dunlop SP-Sport-01V, with a tire size of 235/50-R18-97V. Michelin was founded in 1889 in Clermont-Ferrand, France. Over more than 100 years, it has undergone continuous innovation and development. Michelin tires are marketed in over 170 countries worldwide. For the Volkswagen Tiguan's tires in daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves of the tires gradually become shallow. If the tread is worn flat, it will lose its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks may seem minor but can be a hidden danger for tire blowouts at high speeds. Additionally, promptly remove pebbles from the grooves. Try to park on level ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the car near or in contact with petroleum products, acids, or other materials related to rubber deterioration. After parking, the driver should not turn the steering wheel, as this operation accelerates tire wear. Do not splash water to cool down the tires. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure increases. At this time, you should stop to let the tires cool down. It is strictly forbidden to release air to reduce pressure or splash water to cool down, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and emergency braking to prevent accelerated tread wear due to dragging between the tires and the ground.

Where to Install ETC on a Vehicle?

The installation position of ETC for small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the lower middle part. The appropriate installation position should be at a height of no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic Toll Collection. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is handled by a proxy, the proxy's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection seal. Additionally, a bank card under the owner's name for deducting highway tolls is required, and the owner must be between 18 and 60 years old. Here are some precautions for ETC installation: Do not obstruct the driver's view; it is best to install it behind the rearview mirror: Many car models have windshields with a steep incline, which can reduce the driver's field of vision. If ETC installation does not consider this, it may increase blind spots for the driver. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If the ETC is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent issues caused by the malfunction of the ETC device of the vehicle in front, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic toll deduction for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and toll deduction failure. When using a debit card linked to ETC, insufficient balance may also lead to toll deduction failure.

Are There Differences Between China 6 and China 5?

The differences between China 5 and China 6 emission standards are as follows: Different Emission Standards: China 6 emission standards are more than 30% stricter than China 5. Excluding the influence of operating conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different Implementation Times: The China 5 standard was implemented nationwide on January 1, 2017, as the fifth-stage national motor vehicle emission standard. China 6 has been implemented since July 1, 2019. Different Principles: During the China 5 phase, diesel and gasoline vehicles had different emission standards, but China 6 adopts a fuel-neutral principle, meaning that regardless of the fuel type, the emission limits are the same. Different Issuing Authorities: The China 5 standard was issued by the Ministry of Environmental Protection; the China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different Letter Representations: China 5 is represented by 'V'; China 6 is represented by 'VI'. Different Monitoring Requirements for Plug-in Hybrid Electric Vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China 5 Standard Limits: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b, as follows: China 6a Standard Limits: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM (particulate matter) per kilometer driven. China 6b Standard Limits: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 mg of PM (particulate matter) per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted in normal use, with no driving bans or license plate restrictions, their resale value is significantly impacted. For truck owners, if they purchase a truck on loan for cargo transport, after repaying the loan, the vehicle's depreciation is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, with longer service life and more road rights, have greater advantages.

Should You Use Internal or External Air Circulation When Turning on the Heater?

Whether to use internal or external air circulation when turning on the heater depends on the situation: use internal circulation for short trips and external circulation for long trips. Internal and external air circulation in a car refer to: 1. Internal circulation means the air conditioning system is closed to outside air, only recirculating the air inside the car; 2. External circulation means the car's air conditioning system is open to outside air, drawing in fresh air from outside the car. The functions of a car's air conditioning system are: 1. To cool, heat, ventilate, and purify the air inside the car; 2. To provide a comfortable environment for passengers, reduce driver fatigue, and improve driving safety.
