What kind of oil should be used for a 1.5t engine?

[DePhoebe]

1.5t engines use fully synthetic oil. Here is more related information: Introduction to engine oil: 1. The working environment of a 1.5T turbocharged engine is more demanding than that of a naturally aspirated engine, so the requirements for lubricating oil are higher. Generally, 5W-40 fully synthetic oil is required. If you frequently drive aggressively, 5W-50 should be used. 2. For example, in "15W-40, 5W-40," the "W" stands for Winter. The smaller the number before it, the better the low-temperature fluidity of the oil, indicating that it can be used in lower environmental temperatures and provides better protection for the engine during cold starts. For instance, 5W represents resistance to external temperatures as low as -30°C, while 20W is resistant to -15°C. 3. The number after the W represents the kinematic viscosity of the oil at 100°C. The higher the number, the higher the viscosity. 40 means the kinematic viscosity standard at 100 degrees Celsius is between 12.5mm2/s and 16.3mm2/s, and it definitely does not mean, as some rumors suggest, that it can be used below 40°C.
