What is the difference between 0w20 and 5w30 fully synthetic engine oil?
1 Answers
0w20 and 5w30 differ in low-temperature applicability and viscosity. Here are the details: Different low-temperature applicability: 0w20 has a low-temperature startup performance rating of 0; 5w30 has a low-temperature startup performance rating of 5. Different viscosity: 0w20 has a viscosity rating of 20; 5w30 has a viscosity rating of 30. Meaning of 'W' in engine oil classification: The 'W' in engine oil classification stands for Winter. The smaller the number before W, the better the oil's low-temperature fluidity. The larger the number after W, the better its high-temperature protection performance. Engine oil is the lubricant used in engines. Base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve deficiencies in base oil performance, giving it certain new characteristics.
