My yukon xl is getting 17 city which isn't bad with the flex fuel shut off thing 19.5You show me yours, I’ll show you mine.
I know they say if you're buying a big SUV you shouldn't care about the gas mileage but I'm not one of those. I would be quite interested to know what our courageous buyers are seeing especially on the 5.3L. Trips, combined city highway, from the DIC or hand calculated all will be appreciated. How fast you drive, load of vehicle, etc.
2020 Yukon, 5.3 4wdr, 14,000 miles. I am averaging 21.5 overall. I use cruise control when ever I can, the vehicle on the current tank is running 22.5. I had a couple of 500 hundred mile trips on one tank of fuel. Love the vehicle, not one service issue since new, excluding o8l changes.I know they say if you're buying a big SUV you shouldn't care about the gas mileage but I'm not one of those.
