What is your total weight of trailer and Excursion rolling down the road?
Traveling at NORMAL posted speeds, what is you mileage.
Just assembling some data points.
Not sure what the total weight is (I have never gone to any scales), but I tow a ~9,000 lb. trailer behind my EX and have myself, my wife, two kids and two dogs along with a bunch of camping stuff (including firewood) in the back. Has to be pretty heavy.
~7,200# of vehicle + ~800# of occupants & gear + ~5,400# of car trailer (loaded) = ~13,400#
600 mile round-trip from the coastal area of Virginia over some of the Appalachians and back, averaged 11.3 MPG calculated (not overhead display, which BTW said 11.7 MPG). Dropped out of overdrive maybe 4 times while making climbs (2 times in each direction). 60% of trip was interstate highway, and the remainder was 55MPH-roads with occasional traffic lights.
My ol' '87 F350 crew-cab could never do any better than 8 MPG while towing ... and only 10 MPG all the other times (it had a 5.8L gas V8 with tall rear-end gear ... US Govt. surplus truck). on the plus side, the only time the F350 ever failed me was when the battery expired ... and the battery was only 7 years old then. (lol)

Originally posted by crjackson With gear and family in X weighing about 8800 lbs, pulling an 8500 lb TT driving north from SF, CA on 101 (pretty hilly) we averaged 8.6 mpg.
I have towed that particular road and it is hilly, you are getting what I believe is the normal for that combination.
Thanks

Landyot,
Thanks for the info; this is exactly what I was looking for, happy that I am starting to get some responses to this. I know I am not the only one that is curious about this.
I do know and understand that terrain will cause a difference in the MPG….this is just a base line, and the start of a good one. I have found that even leaving in the Tow-Haul mode kills mileage quick. It is wonderful going down hills and starting from a stop!
Originally posted by Tim Lamkin Rob what kind of MPG are you getting?
I average right around 10-11 mpg. Now mind you this is if I keep the speed down to 65 or so mph. Mileage really goes into the shi**er at 70+, or when traversing hilly roads.
I noticed that, too ... MPG decreasing as speed increases. My other vehicles get better MPG at 80 MPH than at slower speeds ... but not the Might-X Now wouldn't it be interesting if some company like Diablo or Hypertech could develop a program that allows the V10 computer to shut down every other cylinder when cruising at 70 MPH or so? And make it so the "offed" cylinders alternate so you are not running on the same 5 cylinders all the time? The V10 already has such a program written into its code that does this when the engine overheats.
Once a vehicle reaches cruising speed, it does not need all of the available power to maintain that speed ... and my X has shown it gulps more fuel at 80 MPH than at 65 to 70 MPH.
Hmmm ... now the hair-topped computer is wondering about an old device that was be set-up for overdrive or undersdrive (depending on which way you installed it) ... and it attached to the aft end of the transfer case ... available for use only in 2WD. (Mental note to research that thing later.)

Hmmm ...
Interesting my 01 V10 actually made better mileage at 82 than at 75 anything over and it went in the basement FAST.
Pulled my John Deere tractor awith trailer with total weight of !12,500 lbs. At 70 mph I maintained 13.3 mpg according to overhead readout. This is with the 6.0 powerstroke

Way cool, and good mpg. Is it flat where you are pulling?
I made a 1400 mile round trip, half on flat land, half on mountain grades, pulling a 30' Weekend Warrior (too long for an Excursion), loaded at 20,200 lbs total combined weight (way too heavy for an Excursion), doing the speed limit or less, with a V10, 4.30 gears. I averaged 5.43 mpg for the trip Not to mention it STRUGLED up the hills. Hence why I bought an F350 to handle the wheelbase problem and a 6.0L diesel handle the weight problem.
Towing a 5000 lbs open car trailer, though, the V10 barely knows its back there and gets a minimal difference in fuel economy from the normal everday city driving I do, 10 mpg istead of 10.5 mpg.
