Mercedes-Benz GLC-260L uses engine oil with the specification 5w40 (7L), which is fully synthetic oil, and the replacement interval is 10,000 kilometers. Functions of engine oil: Lubrication: When the engine is running, the friction between components is rapid and intense. A sufficiently thick oil film is required between the piston and the cylinder to separate the two components and reduce friction. Cooling: The engine generates a large amount of heat during operation, and the engine oil carries some of the heat back to the oil pan for dissipation. Cleaning: Oil sludge, carbon deposits, metal wear particles, and inhaled dust can form on engine components, leading to carbon buildup. The engine oil circulation ensures cleanliness.

Can Blue and Green Antifreeze Be Mixed?

Blue and green car antifreeze should not be mixed. Different manufacturers use different additives, which may lead to incompatibility and potential chemical reactions. Therefore, it is best to avoid mixing them. The antifreeze properties come from components like glycerin or isopropanol in the antifreeze. Precautions for using car antifreeze: Use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could cause chemical reactions between additives, rendering them ineffective. Replace antifreeze regularly—every two years or every 40,000 kilometers. Taxis should replace it more frequently. When replacing, drain the old fluid completely, clean the cooling system thoroughly, and then add new fluid. Avoid diluting with water. Traditional inorganic antifreeze should not be diluted with water, as it may cause precipitation and severely impair its functionality. Organic antifreeze can be diluted with water, but excessive dilution should be avoided. Some antifreeze may develop small flocculent precipitates after storage for a year. This is usually caused by additive separation and does not mean the antifreeze should be discarded. However, if large particle precipitates appear, the antifreeze has deteriorated and should no longer be used. Maintenance precautions for antifreeze: Do not directly pour concentrated antifreeze. Some drivers and mechanics may mistakenly believe that purer antifreeze is better or that higher ethylene glycol concentration is preferable. Directly adding concentrated antifreeze not only fails to meet the required freezing point but can also lead to unexpected issues, such as antifreeze deterioration, increased low-temperature viscosity, and higher engine temperatures. Regularly check antifreeze during use. Antifreeze has a shelf life of two years, so continuity is important. To minimize waste, avoid unnecessary replacement after adding antifreeze.

How Long Does the First Maintenance Take?

For the first maintenance of a new car, it is recommended to change the engine oil at 3,000 kilometers, and then perform maintenance every 5,000 kilometers. Below are some relevant details about the first maintenance: 1. Generally, 4S shops recommend doing it earlier. The first maintenance time for a new car is usually determined by either the mileage or the specified first maintenance time, whichever comes first. 2. Typically, the first maintenance for a car is scheduled between 3-5 months, with the mileage ranging from 3,000 to 5,000 kilometers, and for some cars, it can even extend up to 8,000 kilometers. This variation is due to differences in the specific technical conditions of the vehicles. 3. The engine of a new car has a break-in period. Different brands and models of cars come with different engines. Some engines use special technologies that require strict oil specifications; others are made with special materials and high precision, resulting in relatively less wear.

What is China VI?

"China VI" emission standards, the full name of which is National Sixth Stage Emission Standards for Motor Vehicle Pollutants, is an upgraded standard based on the domestic situation of China, building upon the "Limits and Measurement Methods for Emissions from Light-duty Vehicles (China V)". Here is an introduction to the new China VI standards: 1. Addition of OBD (On-Board Diagnostics) checks. If a vehicle's fault light is on or fault codes are detected in the engine system, it will be deemed unqualified and fail the annual inspection. 2. Introduction of checks for the readiness status of the engine system, such as whether the oxygen sensor is in a ready state or if the three-way catalytic converter has reached readiness. If these components are not in a ready state, the vehicle will not pass the annual inspection. 3. While China V standards used the NEDC (New European Driving Cycle) for both emission and fuel consumption tests, China VI standards continue to use NEDC for fuel consumption tests but adopt the more stringent WLTC (Worldwide Harmonized Light Vehicles Test Cycle) as the emission test cycle.

What does Mercedes-Benz sedan V12 mean?

Mercedes-Benz V12 refers to models equipped with a V12 engine. The following are specific details about Mercedes-Benz: 1. Mercedes-Benz cars equipped with a V12 engine will have a V12 badge on the side of the fenders: Very few Mercedes-Benz cars are equipped with a V12 engine due to strict emission regulations, and there are no models in the Mercedes-Benz S-Class that use a V12 engine. 2. The new Mercedes-Benz S-Class is equipped with a total of four engines: a 2.0-liter turbocharged engine, a low-power version 3.0-liter twin-turbocharged engine, a medium-power version 3.0-liter twin-turbocharged engine, and a high-power version 3.0-liter twin-turbocharged engine. 3. The Mercedes-Benz model with a V12 engine is the Mercedes-Benz S-Class AMG model: The 6.0-liter twin-turbocharged V12 engine used in the Mercedes-Benz S-Class AMG has a maximum power of 463 kW, a maximum torque of 1000 Nm, a maximum power speed of 4800 rpm, and a maximum torque speed range of 2300 to 4200 rpm. The engine also features multi-point fuel injection technology and uses an aluminum alloy cylinder head and block.

What can the Haval paddle shifters do?

Haval paddle shifters are gear shift paddles that can upshift or downshift the vehicle's transmission. Here are the specific details: 1. Paddle shifters are the car's gear shifting devices that can bypass the gear selector lever on the transmission: The driver can directly shift gears by pulling the paddle shifters. As a quick gear shifting device, paddle shifters can greatly enhance the driving operability. 2. Using paddle shifters, the driver can complete upshifting and downshifting operations without taking hands off the steering wheel: The paddle shifters are located on the left and right sides of the inner arc of the steering wheel. Pulling the paddle shifters toward the driver with the index and middle fingers is for upshifting, while pressing them toward the steering wheel with the thumb is for downshifting. When the vehicle is in D (Drive) mode, the driver can manually force the transmission to shift gears at any time with fingers, which is very useful when rapid acceleration is needed for overtaking.
