What is the viscosity grade of Nissan's engine oil?
2 Answers
Most Nissan vehicles use engine oil with a viscosity grade of 0W20 or 0W30, which can be adjusted based on driving conditions and habits. Engine oil is not brand-specific to any particular car model; the correct viscosity grade selection is what matters. Below is relevant information about engine oil: 1. 0W30 refers to the SAE standard viscosity value, indicating that the oil is multi-grade. 2. The 'W' stands for WINTER, and the number before 'W' represents the oil's flow performance at low temperatures—the smaller the number, the better the cold-start performance. The number after 'W' indicates the oil's stability at high temperatures—the larger the number, the better the high-temperature stability. 3. The smaller the number before 'W', the lower the oil's low-temperature viscosity, the better its low-temperature flow performance, and the lower the minimum applicable temperature.
When I first bought my Nissan Sylphy, I was also quite confused about the engine oil grade. After driving it for two years, I’ve learned that most Nissan vehicles use either 5W-30 or 0W-20, depending on the model’s age. My manual clearly recommends 5W-30 full synthetic, especially in our southern region where it gets hot in summer—it helps protect the engine from overheating. Never use the wrong viscosity; older grades like 10W-40 can actually clog the oil passages. I once tried the wrong grade by accident, and my fuel consumption shot up by 10%. I recommend changing the oil every 7,500 km and checking the fluid level regularly. Nissan’s official website has a lookup tool—just enter your model and year to find the correct grade. Paying attention to these small details can really extend your engine’s lifespan.
