Fuel tank

[ChristopherWatson]

2018 MAX - 28 gal tank. I pull a modified Vietnam M101A1 trailer (replaced military axle and wheels/tires for a normal axle and military "style" tires. Changing the axle and wheels/tires improved gas mileage by about 2 MPG by reducing the trailer weight by about 500 lbs. Trailer has "canvas" top.
I get about 12-13 MPG going back-and-forth to Atlanta area from DC (I95 to I85) regardless of the trailer's load. I drive 75-80 MPH so I don't get run off the road. Very hilly from NC on to GA.

I believe the full tank is bigger on the MAX. For those who choose to buy an Expedition, might as well go all out and get the MAX.

Wish I could have gone for one but Ford wasn't offering their 20% discount on the Max model.

Yeah those ex military trailers are parachutes no surprise on the mileage

I’ve seen comments on here quoting 10 mpg towing several times. Tomorrow I have a 9 hour drive that’s 99% interstate to pick up a overland trailer and drive it home so I’ll get a good look at max MPG with and without trailer... I’m curious to see what it’s shakes out with.

Which trailer are you getting?

I got the Conqueror UEV490

Ok, so I towed this 4500 pound trailer roughly 500 miles yesterday with my Navigator, that has tow package, on a full tank on the interstate and a full tank on secondary roads with a fair amount of twisty mountain road driving. The interstate was through Kentucky and the Daniel Boone National Forest so there were a fair amount of up and down at highway speeds. On interstate I got 10.2MPG and the secondary roads I got 11.4. These numbers aren’t from the car computer, they are from the fuel mileage app I use. Speed is the major factor for better mileage. Highway was 65 to close to 80 MPH at times. I literally forgot the trailer was there until I checked the rear view, I was so pleased with how the Navigator can tow... so flipping easy. The tow/haul mode and trailer brake stuff makes a major difference over towing my regular trailer with no brakes. In the future I plan to make more of an effort to keep the speed down on the highway, both for the safety and MPG.

What app is that and do you recommend it?

How did your app figures compare to the vehicle computer?

I use ‘Car Minder Plus’ to track mileage and all the auto maintenance... this one will let you have multiple cars on it. I also use ‘AUTOsist’, it lets you do the same thing but also upload images or pdf’s per service so you can keep the actual paperwork with any work you enter. I like both but the second one only does one vehicle unless you pay. I also track the maintenance on some of my small gas engine stuff on the first one and multiple cars. I recommend either one so maybe try both and see what you think. I have iPhone so I can’t comment on any droid apps.

Computer showed a higher MPG than the apps by about half a gallon. This is what I found doing actual a math on paper comparison a year ago.
