What kind of engine oil is best for the Beijing Hyundai Langdong?

[McMaddox]

Beijing Hyundai Langdong can use the manufacturer-recommended engine oil with a viscosity of 20 or 30, specifically the 5W30 model. Below are the detailed explanations: 1. The type of engine oil used must ensure the normal operation of the Langdong engine: The Langdong engine has a relatively precise structure with small gaps between internal components. Using low-viscosity oil can save fuel and allow the engine to perform at its best. 2. Between the 5W30 and 5W40 models, the Langdong is more suitable for 5W30 oil: The higher viscosity of 5W40 oil increases engine resistance and fuel consumption, whereas 30-viscosity oil is sufficient for the Langdong engine. 3. Different oil brands have different focuses: If you prioritize long-lasting performance, you can use Mobil lubricants; if you need strong cleaning capabilities, Shell lubricants are a good choice; and if you require oil with strong film toughness, Castrol oil is recommended.
