Actual gas mileage

[Robert Smith]

Hi again everyone.

I am going to take my first trip across country in my Expedition without my travel trailer. Can anyone give me a reasonable expectation as to fuel mileage? Probably two passengers, a dog, and luggage.

Thank!

I wouldn't take my expy on a trip lol I've never seen it get higher than 12.9mpg, but in reality you should expect 15.5-17mpg, possibly slightly better if you actually maintain using the cruise control for acceleration and deacceleration

 

[Robert Smith]

Thank you. That’s what I was hoping for. I love cruise control so that’s a definite. I love my car too much to not take it

At this moment we are road trippingi from Portland to Las Vegas and am getting almost 15 in my 2014- cruising at 75-80

 

[Robert Smith]

Great, thanks! Drive carefully and enjoy!

I see 19-20 in my lifted 2016 el wth 35s at 63mph on road trips

 

[Robert Smith]

Excellent. I’ll hope for the best, prepare for the worst.

Going to mountains I get 16-17....70-75...on the coast going to beach I can get 20 if I stay under 65...usually get 18-19...2010 EL

In my 05 with the 5.4 3v engine, and 120,000 miles on the clock - the first long trip 500+ miles (one way) we averaged 16.5 MPG at roughly 75 MPH on cruise control.

The 15, 16, and 17 all have the 3.5L EcoBoost engine and get better gas mileage than the 5.4L

I can usually squeeze 16mpg out of it on straight freeway, 75mph, being REALLY gentle. Lately it’s been 12-13 though and I’ve been blaming it on the cold but it’s warmed up a bit around here and I have seen no improvement so I’m going to have to start looking closer at it.

Exactly what mine's been doing. Changed the fuel filter and air filter and haven't seen much difference. Let us know what you find out if you dig into it.

It takes forever for the running average to come back up when it warms up if you reset it you'll see it's doing better

It's the winter gas, you always get lower mileage with the winter formula. Once the summer gas starts flowing, your mileage will go up. If you reset the average you will see a noticeable increase. The system takes the average of the last 500 miles driven so it takes a while for the increases to become apparent.

3" lift and 305mm wide tires. Gets 12-13mpg on the dash computer. Real calculations have yet TBD.

Just put a new set of 275/55/R20 Michelin Defenders LT M/S on my 2014 Limited 4x4. I was getting 14.6 city / about 16 or 16.5 highway on the original Pirelli Scorpions with 63K mils on them. That was not too bad considering what I have read here. We will see what difference these new Michelin's make.

It really depends on how fast you drive, terrain, head/tail winds, traffic. Every mph over 55 increases gas usage. Expys aren't that aerodynamic...push a lot of air.

Although I don't have any long distance trips in mine yet, my highway mileage at 70 mph is 18.5 on cruise control. EcoBoost motor

do the math on miles driven divided by gallons to fill at the pump for your actual mpg.

have a great trip.

We're in the same boat. I'm glad we only drive it less than 200 miles a week

Past 3 weeks been cruising the interstate and seem to consistently get lower mpg numbers during first 45 minutes of driving then it returns to more normal 16-18. I reset it and give it 10 minutes to settle in. I've been trying to determine difference between AWD & 2WD. This is while set on Cruise at constant speed. Oddly I also seem to get same or better mpg in AWD. Need more testing the results seem odd. Its clear that 72mph gets worse mpg than 65mph as expected.

During summer on 80mph roads out west I get better numbers than I'm seeing now but summer/winter gas blend splains that.
