What type of oil is suitable for the Kia K5?
1 Answers
The original oil specification for the Kia K5 is 5W-30, and you can choose between fully synthetic oil, SM or SN grade, with an oil capacity of approximately 4 liters. For later maintenance and oil changes, you may opt for brands such as Mobil, Shell, Castrol, or Total. The viscosity of engine oil changes with temperature, so it's crucial to pay attention 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 vehicle. The latter number represents the oil's kinematic viscosity at 100°C. A higher value indicates better viscosity retention at high temperatures, which can also be understood as superior lubrication performance under high-temperature conditions. The method for changing the oil in a Kia K5 is as follows: Wait for the engine to cool down, allowing the oil to drain back into the oil pan. Use a wrench to loosen the 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 passages to drain out. 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 oil through the oil filler cap on the engine's valve cover. Typically, about three-quarters of a standard oil bottle is sufficient. Start the engine and let it run for 5 minutes, checking for leaks around the drain plug and oil filter. If any leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to check that the oil level is within the standard range.
