What type of engine oil is suitable for Kia KX3?
1 Answers
Kia KX3 can use 5W40 or 0W40 engine oil. Currently, the best-selling engine oils on the market include Mobil, Shell, and Castrol. The viscosity of engine oil changes with temperature, so special attention is needed 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 second 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 a Kia KX3 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 no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passages to drain; Use a specialized wrench to remove the oil filter; Apply oil to the gasket 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, typically filling up to 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. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check if the oil level is within the standard range.
