my wife had an 01, stock hwy 16-18mpg

chipped & opening up exaust, hwy 18-21mpg

 

I've got an '01 and I hit 20mpg with cruise on highway and about 16 in town....No Bull. I bought mine for this very reason two weeks ago.
And I can't hardly tell when I'm towing my Full size Jeep. Only mods on my truck are intake and exhaust. I have Cali emmissions on my truck.

 

Here's my data over 64 hand calculated fuel ups. My modifications are listed. The larger tires that came with my used Excursion hurts my mileage, but the 203* thermostat has helped on my 7.3's.

The X...sometimes pulling the big trailer (Ford Excursion) | Fuelly

Includes towing information, attempts at additives, etc.

Your geographic location will impact winter mileage. Can get pretty cold here in Wisconsin. That, along with lower Btu winter fuel, impacts mileage in cold months for me.

 

WOW SD26, that is one impressive spread sheet. thank you for sharing. those numbers are very helpful and a bit disappointing at the same time but at least it is realistic. thank you

 

LOL! Yeah, life sucks, eh? Yes, I nearly hit 19MPG a few times. My life time MPG includes towing a big trailer and a small trailer. Does have an impact in the overall average. As does winter in Wisconsin. 13-14MPG in the cold seems to be pretty regular for me. Definitely is in the 16-17MPG range in the summer. My regular work commute is about 24 miles, so I get good and warm. It's not interstate driving; it's rural, mostly, has about ten stop signs, and takes me 35 minutes plus to do. So, I wouldn't call my MPG highway. That kind of helps, right?

As for the spread sheet, fuelly.com is free. I just like to load it up with data. One has to read it carefully as what goes in the tank might reflect on the next MPG and my driving notes are based upon the previous data's fill.

I don't think my DP Tuner necessarily netted any kind of a real gain in MPG. I would like to go to a narrower tire, maybe a 255/85 or a stock 265/75...or maybe even a 235/85...but that's a cost that I don't want to incur right now. The big 285's look good and have a lot of tread left. Might make a simple air dam for the front. Doubt I will get a big gain on my regular commute, but maybe a little more on long trips.

What kind of MPG are you hoping for? The Excursion is heavy. I think that hurts it, but it is such a comfortable vehicle. There is a real value in having it for it's great towing ability, comfort in people hauling, and general utility. The DP Tuner makes it just that much more fun to drive also. :icon_ford:

 

Does anyone on here really get over 900 miles to a tanks of diesel

I really would like to see it for my self.. I am on a raid trip at the moment and filled my tank to the brim (44 gallons) so we will see I have a 7.3 4x4 and live in flat florida I will let you guys no.. Honestly I think a lot of people on these forums are not taking in account all the facts

 

With a cold air intake and 4inch exhaust:
Summer diesel - I get about 14 to 15mpg in the city.
On the highway - I've gotten 19mpg, but not using any A/C or Cruise.
I found that if I used the cruise - I lost 2mpg on the highway.

 

My mileage is similar to SD26's. I have MBRP 4" exhaust, AIS intake and hydra chip set on 80hp tune. I use Diesel Kleen too. I've only had the beast for a few months, about 8k+ miles. Big difference between city and highway. The excursion hates traffic but loves to cruise at 65.

 

You should have no issues hitting 20 highway MPGs. I get 18-19 summer 16-17 winter. Mostly highway miles.

20mpg hwy keep it under 70 mph

 

Ive driven all interstate road trips and got 21.5 . we get about 16 -17 in town. Its running stock with 3:73 gears running LT285/75R17's

Ours is a 2000 Ex &.3 with 315,000 miles

 

Does anyone in this thread have a 2wd EX? If not can someone chime in on what a 2wd 7.3l average mpg is?

 

I would say it's going to be very close to a 4x4.

 

We get 13-14MPG avg city/hwy with ours, keeping it under 70. 2WD 200k and bone stock California emissions. What are we doing wrong? Wife drives like a granny. I think I'd need to hook it to the back of a semi and put it in neutral to see 20 the way this thing drinks the juice...

 

Mine with stage 1's 160 stock nozzles, TW tunes and a 38r gets 16.5 towing 10k, just checked and 18+ on the Hy.

 

4wd 2.5inch lift , 33inch mud grabber tires , 4 inch straight pipe aih delete , intake and 6 pos chip set on 75 hp , i get 16.5 mpg hwy ( mountains) and about 14 mpg city hwy mix .....thats doing calculation right at the pump

 

2001 7.3 4x4 LTD. I'm about as stock as you can find these anymore, with 283k miles, we get around 15-17 city and right around 20mpg highway depending on how much I speed.

 

I'm not the most careful driver but I have a hard time believing some of these numbers.

2000 Ex 4x4 Limited

Big filter - 4" MBRP turbo-back w/ muffler - SCT 90 Tune

Running 285s and a level kit.

I have an app that calculates costs and such including mileage.

Best I have seen is a combined 13.86mpg.

 

Your right shiny armor. Quite a few on here that are delusional with their #'s. I've owned 15-20 6.9/7.3 IDI's 92-97,&99-03 including trucks a E-350 15 passenger yoder otter& our excursion. General rule of thumb is 94/up psd's will get 12-14 city 16-18 hwy. keep in mind there r variables, ( miles, condition& prior maintenance , gear ratio , auto or manual, empty or towing etc.etc.) if someone tells you they are getting 15 mpg or better towing 10,000 lbs or more just turn around & walk away.

 

My 2000 with a 4" lift and 35's was 14. I would refer to the Fuelly App and browse the excursions on there. You can see all the excursions , different years , drivetrains , and get a real world idea of what to expect , not what someone netted one time or someone going off the overhead display. Going off Fuelly will give you the BEST and most accurate idea of what to realistically expect , period.
