What kind of engine oil is suitable for Changan CS55?
1 Answers
Changan CS55's original engine oil model is SL-grade 5W-30 mineral oil. This oil is economical and reliable, having undergone precise matching and rigorous verification by the manufacturer, ensuring normal usage and engine longevity. Additionally, Shell brand engine oil is recommended for Changan CS55, with an oil fill quantity of approximately 4 liters. 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, resulting in smoother cold starts for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher number 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 engine oil in Changan CS55 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 to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; apply 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. Generally, fill about three-quarters of a 4-liter oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
