Is the original engine oil for Lavida 5W-30 or 5W-40?

What is the function of refrigeration oil?

In the compressor, refrigeration oil mainly serves four functions: lubrication, sealing, cooling, and energy regulation. Below is a detailed introduction to refrigeration oil: 1. Lubrication: Refrigeration oil acts as a lubricant during compressor operation, reducing friction and wear, thereby extending the compressor's service life. 2. Sealing: Refrigeration oil provides a sealing function in the compressor, ensuring sealing between the piston and cylinder surfaces, as well as between various rotating bearings, to prevent refrigerant leakage. 3. Cooling: While lubricating the moving parts of the compressor, refrigeration oil carries away the heat generated during operation, keeping the moving parts at a lower temperature, thereby improving the compressor's efficiency and operational reliability. 4. Energy Regulation: For refrigeration compressors equipped with energy regulation mechanisms, the oil pressure of the refrigeration oil can be used as the driving force for the energy regulation mechanism.

What is the difference between Maserati leather and genuine leather?

Maserati leather is genuine leather. Genuine leather is made from animal hides and processed, conceptually opposed to artificial leather made from chemical fiber materials. In the market, genuine leather generally refers to one of three types: top-grain leather, split leather, or bonded leather, with prices decreasing in that order. Below are some additional details: 1. Legality: According to the Light Industry Standard BT133-2010 "Handbags and Backpacks" Amendment No. 1 and QBT255-2010 "Travel Bags" Amendment No. 1, revised regulation 4.4 states: if the surface material is more than 90% top-grain leather (excluding laminated leather), it can be labeled as genuine leather. 2. Genuine leather: Car seats use various types of genuine leather, including top-grain leather, bonded leather (containing genuine leather components), microfiber leather, and so-called Maserati leather (microfiber, split leather), among others.

Can I Still Drive When the Maintenance Mileage is Due?

You can continue driving, but it is recommended to schedule maintenance as soon as possible. Below is more information about vehicle maintenance: 1. Vehicle maintenance generally refers to routine service items performed within the manufacturer's specified time or mileage after the car has traveled a certain distance, aimed at ensuring vehicle performance. 2. Car maintenance includes changing the engine oil and oil filter. The maintenance interval depends on the effective duration or mileage of the oil and oil filter used. The validity periods vary among different brands and grades of mineral oil, semi-synthetic oil, and fully synthetic oil. 3. Oil filters are generally divided into standard and long-life types. Standard oil filters are replaced along with the oil, while long-life oil filters have a longer service duration.

What are the reasons for a sudden increase in car fuel consumption?

The reasons for a sudden increase in car fuel consumption include the following: 1. Failure to match or unsuccessful matching with the engine control unit after cleaning the throttle body. 2. Faults in the engine's electronic control system, leading to an overly rich air-fuel mixture and increased fuel consumption. 3. Damage to the engine ignition coil or spark plugs, fuel injector leaks, etc., resulting in higher fuel consumption. 4. Malfunction in the engine cooling system, causing the engine temperature to remain too low and stay in warm-up mode. 5. Excessive carbon buildup in the engine, leading to incomplete combustion. 6. Faults in the fuel tank ventilation system, causing fuel vapor leaks.

What Causes No Airflow from Car Air Conditioning Vents?

Here are the reasons for no airflow from car air conditioning vents: 1. The gear switch or knob is not properly adjusted to the correct position. 2. Damage to the air duct diverter valve. First, check if the vents are open and if the switch is properly adjusted. If the vents are open but there is still no airflow, inspect for any blockages in the vents. It is recommended to seek assistance from a professional auto repair shop. Here is some related information about the air conditioning system: 1. Parameters that can be set for the car air conditioning include the compressor cooling switch, temperature level, vent direction, airflow volume, internal/external circulation, and windshield defogging. 2. The left knob adjusts the air conditioning temperature—clockwise to increase temperature and counterclockwise to decrease it. The middle knob controls the vent direction; adjusting it to the windshield defogging position activates the rearview mirror heating when the middle button is pressed. The right knob regulates the airflow volume, and the middle button sets the air circulation mode.

What does car displacement mean?

Car displacement refers to the volume of fluid inhaled or discharged per stroke or cycle. The space volume that the piston moves from the top dead center to the bottom dead center is called the cylinder displacement. If the engine has several cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, which can represent the size of the engine better than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the displacement. The following is an introduction related to displacement: 1. Most domestic cars have a car model composed of pinyin letters and Arabic numerals at the rear, which includes the following three parts. The first part consists of 2 or 3 pinyin letters, which is the code to identify the name of the enterprise. 2. Generally, the larger the displacement, the more energy the engine releases per unit time (that is, converting the chemical energy of fuel into mechanical energy), which means better "dynamic performance". Therefore, off-road vehicles and sports cars usually have relatively large displacements.
