What type of oil does the CS55 use?
1 Answers
The original factory oil specification for the CS55 is SL grade 5W-30. If you wish to change the oil during later maintenance, you can choose from brands such as Mobil and 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 low temperatures of -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 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 CS55 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 the new oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a bottle. 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 if the oil level is within the standard range.
