What type of oil is suitable for the Changan CS85 COUPE?
1 Answers
Changan CS85 COUPE is best suited with the original 5W30 engine oil. 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 varies with temperature, so special attention must 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, 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 the Changan CS85 COUPE 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 it stops flowing. Start the engine for about 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 the new oil through the oil filler cap on the engine valve cover—usually, fill 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 and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
