How many liters of oil are needed for a BMW X3 oil change?
1 Answers
Approximately 4.8L of oil is required for a BMW X3 oil change. The recommended oil type for the BMW X3 is 5W-30. If you plan to change the oil during later maintenance, you can choose brands like Shell, Mobil, or Castrol. The official manual recommends oil specifications such as 0W30, 5W30, 5W-40, or 0W20. The viscosity of engine oil changes with temperature, so it's important 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 car. The second number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The steps for changing the oil in a BMW X3 are 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 drain plug and place an oil pan underneath to catch the old oil until it stops dripping. Start the engine for about 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 seal of the new oil filter and tighten it clockwise by hand. Add the new oil through the engine valve cover filler port—typically, fill about three-quarters of the oil bottle. 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.
