XL 2008 Automatic Gasoline mileage: 300 KM or more Peace, mercy, and blessings of God be upon you. For sale: Yukon XL 2008, mileage 400,000 km. Engine and transmission are clean. I've used it for 10 years. I travel long and short distances with it, ماشاء الله (Masha'Allah - God has willed it), it has no issues. Its AC is like ice. Notes: A light scratch under the right door and the one behind it. When filling up with gasoline, if you turn it on, it delays starting. I haven't fixed it; it's a part related to the fuel system. The airbag light is on due to a sensor only. The car that takes it will not suffer, God willing. The vehicle's fuel consumption is excellent.
