Tenth-generation Civic: 0W20 or 0W30?

[KarterAnn]

The Civic uses 0W20. In fact, the difference between 0W20 and 5W30 is not significant, and both can be used. However, 0W20 has lower viscosity than 5W30, making it more suitable for colder regions, while 5W30 is commonly used in North China. Below is some relevant information: 1. Engine oil refers to the lubricant specifically designed for internal combustion engines, which also provides functions like rust prevention and cooling. Common grades include 0W20, 0W40, etc. The 0W20 grade is characterized by good high and low-temperature fluidity, meaning it is relatively thin. 2. Specific characteristics of 0W20: The "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating it can be used in lower environmental temperatures and offers better engine protection during cold starts. The number after the "W" (after the hyphen) represents the oil's high-temperature resistance; the larger the number, the better the oil's protective performance at high temperatures. In other words, this oil provides good cold-start performance and remains relatively thin at high temperatures.
