what is a realistic fuel economy on a stock 6.0 excursion?

I am in the market for an excursion but before I pull the trigger I would like to know a realistic fuel economy of these 6.0 excursions when they are bone stock, no lift, stock tires, no chips

I know it depends on how you drive them so please let me know when you drive them without flooring them what is the best you have experienced?

I really appreciate you guys feedback. thank you in advance

Just bought ours this fall and drove from Montana to Washington prior to doing any modifications. Averaged just over 18mpg (hand calc) driving 70mph in the Mountains with a slight head wind. Commuting I seemed to get 17-18mpg. I drive fairly aggressive though. The trip computer seems to always be within a .5mpg. I think it would get right around 20mpg at 65mph if you are easy on the throttle. My trip computer will say 21-22 to 55-60mph but I never drive very far at those speeds to get an accurate tankful mpg. I just did a lot of mods and haven't driven enough yet to figure out what the mpg is now. Hope that helps and good luck. We love ours now.

I have a 05 F-250 (3.73 gears) with a topper on it that weighed in at 8180 lbs when it was at stock height. I consistently averaged 14-15 mpg in mostly highway driving and IMO this is probably what you'll see with the X.

Red....would your 325 tires fit without the lift kit (i.e. would they rub on the sides if the truck wasn't lited?)

Earl
The 325-65/18s would not fit without a lift. They hit on the front when you barely turn the wheel. I have the V codes in front with the Icon 4.5" hangers which gives about 6" of lift. I have about 1" of clearance without trimming anything. I am running 4.5" backspace and get a slight rub on the leaf spring at full turn.

Mileage dropped about 1-2mpg as far as I can tell with the lift. Have not done a road trip to confirm. Other than the mpg loss - we love all the mods we have done.
