What type of engine oil is recommended for the Nissan Sylphy?
1 Answers
Nissan Sylphy's original engine oil model is 5W30. According to the official maintenance recommendations, 5W30 engine oil of SL grade or above should be used. The viscosity of engine oil changes with temperature, so special attention should be paid 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 low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil can maintain 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 drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil 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 allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the filler port on the engine valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to ensure the engine oil level is within the standard range.
