What kind of engine oil is best for Nissan Sylphy maintenance?
1 Answers
Nissan Sylphy uses the original 5W30 engine oil. Between 5W30 and 0W20, the Sylphy is more inclined towards 5W30, which offers better low-temperature fluidity and can adapt to colder environments. The viscosity of engine oil changes with temperature, so it's essential to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The second number represents the oil's kinematic viscosity at 100°C—the higher the number, the better it maintains viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Nissan Sylphy is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan; Use a wrench to loosen the drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to drain the oil from the main oil passages; Use a specialized wrench to remove the oil filter; Apply engine oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for leaks around the drain plug and oil filter. If any leaks are found, perform necessary repairs; After stopping the engine, pull out the dipstick to check if the oil level is within the standard range.
