How many liters of engine oil should be added to a BMW X3?

BMW X3 requires approximately 4.8 liters of engine oil. This vehicle is equipped with a turbocharged engine, and it is recommended to use fully synthetic engine oil. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Taking the 2021 BMW X3 xDrive25i Luxury Package as an example: it is a mid-size SUV produced by BMW Brilliance, with dimensions of 4717mm in length, 1891mm in width, and 1689mm in height, and a wheelbase of 2864mm. It is powered by a 2.0T turbocharged engine with a maximum power output of 135kw and a maximum torque of 290nm, paired with an 8-speed automatic transmission.

Should the Classic Focus use 92 or 95 octane gasoline?

The Classic Focus is recommended to use 92 octane gasoline. The standard for selecting gasoline grade is the compression ratio of the car engine. Generally, the higher the compression ratio of the engine, the smaller the volume of the combustible mixture being compressed, resulting in more power and lower fuel consumption. 92 octane gasoline has an octane rating of 92 and a heptane content of 8, making it suitable for mid-range cars. Taking the Focus 2021 Sedan 1.5L Manual Fengyue model as an example: it is a compact car launched by Changan Ford, with a length, width, and height of 4647mm, 1810mm, and 1468mm respectively, and a wheelbase of 2705mm. It is equipped with a 1.5L naturally aspirated engine, with a maximum power of 90kw and a maximum torque of 153nm, paired with a 6-speed manual transmission.

What does CVT transmission mean?

CVT transmission refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a discontinuous point but a series of continuous values, thereby achieving excellent fuel economy, power performance, and smooth driving experience, while also reducing emissions. In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft connects to the smaller pulley, which drives the larger pulley through the steel belt. Theoretically, a CVT transmission system can have an infinite number of gear ratios, allowing for more flexible gear settings. It is easier to achieve a balance between gear ratios, speed ratios, performance, fuel consumption, and exhaust emissions compared to traditional transmission systems.

How to Perform Pressure Testing and Leak Detection on Car Air Conditioning?

Steps for performing pressure testing and leak detection on car air conditioning: 1. Correctly connect the air conditioning pressure gauge to the high and low-pressure pipelines of the air conditioning system (red for high pressure, blue for low pressure), then connect the air pump for pressurization. 2. After pressurization, close the high and low-pressure valves of the pressure gauge, let it stand for 10-15 minutes, observe the pressure gauge pointer to check if there is any leakage in the air conditioning system, and locate the leak points. Precautions for pressure testing and leak detection: 1. The pressure for car air conditioning testing is generally around 20-30Bar, which is higher than the working pressure of the car air conditioning system. 2. Note that air conditioning vacuuming and refrigerant addition can only be performed after leak detection. After completing the pressure testing and leak detection and vacuuming, you can directly add the refrigerant.
