Should the Sagitar use 5w30 or 5w40 engine oil?

[DiCalvin]

The Sagitar should use 5w40 engine oil. Whether in terms of viscosity range or performance, 5W40 engine oil is superior. 5W40 oil has a higher viscosity and better sealing properties. In the 'w40' designation, the 'W' stands for winter, and the preceding '5' indicates the oil's fluidity at low temperatures. The lower the number, the better the fluidity, with 5w representing an oil's freezing point at -30 degrees Celsius. The Sagitar is a compact sedan under the Volkswagen brand, with dimensions of 4753mm in length, 1800mm in width, and 1462mm in height, and a wheelbase of 2731mm. In terms of power, this model is equipped with two engines: a 1.2-liter turbocharged engine and a 1.4-liter turbocharged engine.
