How many liters of engine oil should be added to the Ford Edge 2.0T?

Ford Edge 2.0T requires approximately 5 liters of engine oil. The detailed information is as follows: Precautions for adding engine oil: After adding engine oil, you can use the oil dipstick to check if the amount is appropriate. It is important to note that you should wait for three minutes after turning off the engine before checking the oil level with the dipstick. Reason for waiting three minutes after turning off the engine: The three-minute wait allows the oil to flow back into the oil pan, ensuring a more accurate measurement. Additionally, make sure the vehicle is parked on a level surface, not on a slope. If the vehicle is on a slope, it will tilt, causing the oil in the oil pan to tilt as well, resulting in an inaccurate oil level reading. Requirements for engine oil: Since the Ford Edge 2.0T is equipped with a turbocharged engine, and turbochargers operate under high temperature and high-speed conditions, the engine oil requirements are higher. It is necessary to use fully synthetic engine oil.
