What is the difference between 0w30 and 5w30?
1 Answers
0w30 and 5w30 differ in the following aspects: 1. The letter 'w' stands for winter. The number before 'w' represents the oil's low-temperature fluidity. A smaller number indicates better low-temperature fluidity of the oil. 2. The number after 'w' represents the oil's viscosity grade. A larger number indicates higher viscosity of the oil, meaning better protection for the engine under high-temperature conditions. 3. The choice of oil should be based on the engine's operating state under high temperatures. A higher number after 'w' indicates better viscosity of the engine oil, providing superior protection for the engine in high-temperature conditions.
