What category is Great Wall JP1 base oil?

[LeAlejandro]

Great Wall JP1 is a Group IV base oil. Below is an introduction to engine oil: 1. Engine oil basics: Engine oils can be broadly categorized into two types - mineral oil and synthetic oil. Synthetic oils are further divided into semi-synthetic and full synthetic oils, with the fundamental difference lying in their base oil composition. In terms of performance, synthetic oils outperform mineral oils in both low and high temperature environments. As the saying goes, you get what you pay for, hence synthetic oils are more expensive than mineral oils. 2. Viscosity rating explanation: In 5W-30 engine oil, the number 5 represents the oil's low-temperature fluidity - the lower the number, the colder the environment it can be used in (5 indicates it can withstand external temperatures as low as -30°C). The W stands for winter, and the final number 30 represents the kinematic viscosity standard at 100°C (30).
