GMC Yukon SLT 2010 Automatic Gasoline mileage: 300 KM or more 4WD Mileage 300, can be increased. The car has no issues, God willing. A while ago, it was in an accident and was repaired. All parts are original, and a 40,000 gear cooler was installed. There was a hit on the chassis and it was fixed. The engine was removed from the bottom for cleaning. The oil pump was changed to a Denali. The car has no issues. The highest offer is 26, and we ask God for more.
