The Difference Between 5W30 and 0W30 Engine Oil?
1 Answers
Here are the differences between 5W30 and 0W30 engine oil: 1. Low-temperature fluidity: 5W30 and 0W30 are engine oil grades, where 'W' stands for winter use. The main difference between the two lies in the number before 'W', which represents the oil's fluidity and the minimum applicable temperature. A smaller number indicates lower oil viscosity, meaning better low-temperature fluidity and a lower applicable minimum temperature. This implies that 0W oil has better fluidity than 5W oil and can be used at lower minimum temperatures. 2. Viscosity grade: 0W30 oil has better low-temperature performance than 5W30 oil. 0W30 has lower low-temperature viscosity and better low-temperature fluidity, making it suitable for colder temperatures, down to -35°C, whereas 5W30 performs slightly worse in low-temperature resistance, with a minimum applicable temperature of only -30°C.
