Which engine oil is best for Sylphy maintenance?
1 Answers
Sylphy's original engine oil model is 5W30. According to the official maintenance recommendations, 5W30 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, where 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 latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a 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 special wrench to remove the oil filter; apply some oil to the seal of the new oil filter and tighten it clockwise by hand; add the new oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of the oil container; start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter, and repair if necessary; after stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
