What kind of engine oil should be used for the 2020 Bora 1.5L naturally aspirated engine?

[Costa]

Volkswagen Bora should use SM or higher grade 5W-40 engine oil. Because the Bora engine operates with high efficiency and has a high compression ratio, which results in relatively high internal engine temperatures, using high-viscosity engine oil can protect various components inside the engine and cool them to reduce the ambient temperature. Below are the relevant details: 1. Selection of viscosity grade: Generally, in winter, 5W is sufficient for most regions, but in some northern areas (such as Jilin Province), it is better to use 0W engine oil to achieve better cold-start performance and adapt to local environmental conditions. For the high-temperature viscosity value of engine oil, 30 or 40 is usually suitable. However, if the vehicle is frequently driven in congested traffic conditions, is older, or is a heavy-duty vehicle used for long-distance transportation, the viscosity of the lubricating oil can be appropriately increased, such as using 0W50 lubricating oil. 2. Selection of brand: For the choice of lubricating oil brand, if you prioritize the long-lasting performance of the oil, you can choose Mobil engine oil; if you focus on the cleaning performance of the oil, Shell engine oil is recommended; if you need oil with strong film toughness, Castrol is advocated. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell engine oil with strong cleaning capabilities can be selected.
