Should Nissan Sylphy use 0w20 or 5w30?

[RafaelFitz]

Nissan Sylphy can use either 0w20 or 5w30 engine oil. Introduction to 0w20 and 5w30 engine oils: The main difference lies in low-temperature fluidity. 0w40 has lower low-temperature fluidity than 5w40. The number 0 indicates that the oil can remain liquid at -40°C, and will solidify below -40°C; the number 5 indicates that the oil can remain liquid at -35°C, and will solidify below -35°C. Generally, 0w40 is used in northern regions, while 5w40 is mainly used in southern regions. Introduction to engine oil: The oil grade usually indicates viscosity and quality. The viscosity of lubricating oil is often identified using SAE grades, where SAE stands for the "Society of Automotive Engineers." The "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. The number after the "W" (after the hyphen) indicates the oil's high-temperature resistance, with a higher number meaning better protection at high temperatures.
