How much engine oil should be added to a Passat 1.4?

[MacReed]

Approximately 4.5L of engine oil should be added to a Passat 1.4. When adding oil, base it on the actual situation, adding it in small amounts multiple times to avoid overfilling, which could damage the engine. Engine oil selection: When selecting engine oil, it's not about choosing the most expensive one, but rather selecting the appropriate oil based on the characteristics of the car's engine and your usual driving habits. You can categorize the selection by the oil used in winter and the oil used in summer. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there's no need to choose oil with a better low-temperature viscosity grade. Engine oil grades: Engine oil grades are divided by quality and viscosity grades. Oil for gasoline engines is usually denoted by the letter "S," while oil for diesel engines is usually denoted by the letter "C."
