Should the Levin use 0w20 or 5w30?

[OLondon]

Both 0w20 and 5w30 engine oils are suitable for the Levin. The differences between 0W20 and 5W30 engine oils are as follows: Different low-temperature starting performance: The 'W' stands for WINTER. The number before the 'W' represents the oil's flow performance at low temperatures. A smaller number indicates better starting performance in cold conditions, meaning 0W20 has better cold-start performance than 5W30. Different high-temperature stability: The number after the 'W' represents the oil's stability at high temperatures (i.e., its tendency to thin out). A larger number indicates better high-temperature stability, meaning 5W30 has better high-temperature stability than 0W20.
