What Kind of Oil is Best for Turbocharged Engines?

[LandonDella]

Turbocharged engines are best suited for full synthetic oil. Here is an introduction to full synthetic oil: Full synthetic oil is a man-made lubricant that undergoes chemical decomposition of various natural substances during production, followed by synthesis with other materials to produce the final synthetic oil. It offers more stable chemical properties, better fluidity, and lower resistance, providing optimal engine protection while reducing fuel consumption. When selecting oil, pay attention to two key indicators: SAE and API. SAE indicates the oil's viscosity grade, while API represents the oil's quality level. In the API quality classification (e.g., "SN" or "CG"): "S" denotes oil for gasoline engines, and "C" denotes oil for diesel engines. If both "S" and "C" are present, the oil is suitable for both gasoline and diesel engines. The letters following "S" or "C" (e.g., from "SA" to "SN") indicate progressively better performance with each increment. Currently, the highest API quality grade is SN.
