What type of oil does the Changan Lingxuan use?

[DiDaniel]

Changan Lingxuan uses 5W30 engine oil, which has strong lubrication capabilities and excellent low-temperature resistance, making it one of the commonly used oil types in the automotive market. If you wish to change the oil during later maintenance, you can choose from brands such as Shell or Castrol. 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 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 value indicates better ability to maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Changan Lingxuan 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 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 oil to the seal of the new oil filter and tighten it clockwise by hand. Add new oil through the engine valve cover filler port, typically filling about three-quarters of a standard oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug or oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to ensure the oil level is within the standard range.
