What is the grade of A3B4 engine oil?

A3B4 belongs to a higher grade of engine oil. A3B4 is one of the standards certified by the European Union, where 'A' stands for gasoline engines for passenger cars, and 'B' stands for diesel engines for passenger cars. The numbers represent the oil quality grade. A3B4 is a higher-grade mainstream lubricant, which is a catalytic type of gasoline and light-duty diesel engine oil. A3B4 is an engine oil standard set by the European Automobile Manufacturers Association (ACEA), representing gasoline engine oils. API is the oil standard certified by the American Petroleum Institute. Although these are two different oil certification standards, there is a certain relationship between ACEA and API. For example, A3B4 is only equivalent to the SL grade in API. The viscosity of engine oil should not be too high or too low. If the viscosity is too low, it will increase engine wear. If the viscosity is too high, it will affect the increase in resistance during engine operation, leading to reduced engine power and increased fuel consumption. When the engine is working, the oil forms a film on the surface of various components inside the engine, which can reduce friction between the components and lower the operating resistance inside the engine. If the oil viscosity is too low, the oil cannot form a stable film, which will exacerbate engine wear. The viscosity of engine oil changes with temperature, so special attention is needed to its performance under low and high temperatures. For example, in 5W-30, the first number represents low-temperature fluidity. 5W means it can withstand low temperatures of -30 degrees Celsius. The smaller this number, the better the low-temperature fluidity. 0W is -35 degrees Celsius; 5W is -30 degrees Celsius; 10W is -25 degrees Celsius; 15W is -20 degrees Celsius; 20W is -15 degrees Celsius; 25W is -10 degrees Celsius. This ensures smoother cold starts for vehicles. The second number represents the kinematic viscosity of the oil at 100 degrees Celsius. The higher the number, the better the oil can maintain its viscosity index at high temperatures, which can also be understood as better lubrication performance under high temperatures. Relatively, the better the low-temperature fluidity, the smoother the cold start for the vehicle, and the better the protection for the engine. For full synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. For semi-synthetic oil, the replacement interval is slightly shorter, requiring replacement every 7,000 kilometers or six months. When choosing engine oil, the following points should be noted: Engine oil should be selected according to the engine's requirements. It is unnecessary to use overly high-grade oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oil should be preferred. Due to its savings, long lifespan, and high efficiency, multi-grade oil provides better protection for the engine. Based on the characteristics of multi-grade oil, it may appear darker and have lower oil pressure compared to regular oil during use, which is normal. Since engine oil greatly affects the performance and lifespan of the engine, it is essential to strictly follow the vehicle's manual to select oil of the same series, service grade, and viscosity grade. The engine oil recommended in the vehicle manual is based on the engine's performance and the temperature of the sales region, providing certain guidance for oil selection and leaving a considerable safety margin.

How to Turn Off Auto Start-Stop?

To turn off the auto start-stop system, the owner simply needs to press the auto start-stop button directly. 1. The dashboard will indicate that the system is off. If you want to use this function again, press the button again to turn it on. 2. Auto start-stop has its drawbacks—it frequently starts and stops the engine, which can cause damage to related components such as the starter and battery. 3. Although vehicles equipped with auto start-stop systems use enhanced starters and batteries, in practice, their failure rates are higher than those of ordinary vehicles without auto start-stop systems.

Does the Porsche Panamera have a shooting brake version?

Porsche Panamera does have a shooting brake version. Here is an introduction to the Porsche Panamera shooting brake: 1. Exterior: The design of this car is very similar to the fuel-powered version, but the height of the car has been increased by 5mm, and the rear space has been expanded to 515 liters. 2. Interior: The car still adopts the Porsche family-style design. The rear seats have been changed from two seats to three seats, making this shooting brake version the first five-seater model launched by Porsche. The design of the center console is relatively simple, with the biggest highlight being the 12.3-inch full LCD instrument panel, which gives the car a more technological feel.

What does Sagitar inspec mean?

Sagitar inspec refers to the car needing maintenance. Many cars have a maintenance reminder function, and the car must be serviced on time to maintain good condition. Maintenance includes the replacement of some fluids and wear parts. The wear parts on the car include belts, brake pads, brake discs, tires, spark plugs, ignition coils, wipers, and various filters. Some cars use an electric power steering system and do not require power steering fluid. The Sagitar has a body length of 4644mm, a width of 1778mm, a height of 1482mm, and a wheelbase of 2651mm. It is equipped with 1.2T, 1.4T, and 1.6L engines.
