What brand of engine oil is best for Nissan Sylphy?
1 Answers
The original engine oil brand for Nissan Sylphy is Shell. If you want to change the oil during later maintenance, you can choose brands such as Mobil or Great Wall. According to the Nissan Sylphy Classic 1.6L engine manual, the older models recommend 5W30 oil, while the latest models recommend 0W20 oil. For the older Sylphy Classic engine during the new car phase, you can use 5W30 and some 0W20 oils, with the requirement that the oil viscosity should be between 8.8-9.3. The commercially available Shell Helix Ultra 0W-20 meets this condition. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C, with higher values indicating better viscosity retention at 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, and also allow the oil to drain 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 passages to drain out. Use a special wrench to remove the oil filter. Apply some oil to the seal of the new oil filter and hand-tighten it clockwise. Add the new engine oil through the oil filler cap on the engine valve cover, typically filling about three-quarters of a standard 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 there are leaks, perform necessary repairs. After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
