What kind of engine oil is best for the Hyundai Elantra?

[OJuliette]

When selecting the viscosity grade of engine oil, it is recommended to choose oil with a viscosity of 20 or 30. Considering temperature conditions, 5W20 or 5W30 oil is suitable for most regions, while 0W20 or 0W30 oil is recommended for extremely cold areas to ensure the proper operation of the Hyundai Elantra's engine. The details are as follows: 1. Due to the Elantra's tightly constructed engine and small surface contact distances between components, using low-viscosity oil can reduce fuel consumption and maximize engine performance. Naturally aspirated engines have lower oil requirements and can use mineral oil, semi-synthetic oil, or full synthetic oil. 2. Compared to naturally aspirated engines, turbocharged engines have a more precise structure and operate under harsher conditions, requiring higher-quality lubricants with better fluidity. 3. When choosing a lubricant brand, opt for long-lasting oil like Mobil, oil with strong cleaning capabilities like Shell, or oil with robust film toughness like Castrol. Turbocharged engines are prone to carbon buildup during high-speed operation, making Shell oil with strong cleaning capabilities a suitable choice.
