If I fill up the tanks on both my vehicles I can run the Bronco tank to almost empty in about 400 miles, this is a 16 gal. tank and my daily driver. The Yukon has the standard tank and it will last for a couple of weeks depending how much I drive it, as the weather improves I drive it more often. I don't miss having to fill the tank on my '19 Yukon because it had a 26 gal tank.
