What Our Members Are Saying about the Real Gas Mileage of the GMC Yukon

GMC Yukon Real Gas Mileage: Pros
YearBody/PowertrainComment
2001 4dr SUV 320-horsepower 6.0L V8
4-speed automatic AWD
Overall 14.2 MPG. In town 14 MPG, on the interstate 18 MPG @ 65 mph, 16 MPG @ 75-80 mph. Would probably have better mileage with more gears than the 4 speed auto but overall a pretty efficient powertrain considering power and weight. see full GMC Yukon review

It does 13.8 - always has from new. GM lies about 17 - not possible. You can dive this with a lead-foot or as gently as you like. Empty or loaded. Makes no odds - 13.8 mpg !! see full GMC Yukon review
