Averaging some good miles. I got this 2015 XLT loaded, it's running like a dream. Daily driver in the country, 4x4.

It was a rental car in Colorado, abused. Didn't have an oil change until 40k. Put some 0w30 in there and a drop in K&N filter.
Well then I guess my 17 with 4900 miles on it might do better once it grows up. because I'm only getting 17.3 average on the highway at 78 MPH.

You all make me jealous. I've got a 2013 EL 4WD and using the calculator method, I got around 12. Then again, I've got a lead foot, it's almost always in 4WD, and I drive it on cheaper 87 octane gas.

2000 XLT 4.6l. I get between 12-14 city 15-18 hwy. I previously owned a 1999 Town Car, 4.6l. It got around 18 city and 23 hwy. I know the Expy weighs more, but mileage was way higher. The Town car, felt like it had much more power. Anyone mess with a SCT tuner?

Just did first trip with new 2017 Expedition Limited, white frost/dune/standard length. Almost all flat interstate mostly 72-76mph, easy cruise. Actual measurement (not computer) 18mpg, guess that is ok given what I am reading here, only 400 miles on it
Traded in 2010 GMC Acadia with 94K on it, Ford rebates just too good to pass up and new Acadia shrank 30% but they kept same price. Did not want 2018 Chevy Traverse due to STOP/START system on it, reminds me of hillbilly gas golf cart in the NC mountain courses!
Ford gave my more for my trade than GMC garage that did all the service for 7+ Years! Acadia would get 21 mpg on long hauls but brakes locked up last mountain trip and I decided that it was time to switch.
Expedition will be used exclusively for long interstate trips as our grown kids and families are 9 hours away as well as other retirement travelling. That is the only kind of travelling I did with the Acadia as it was a porker too!

Welcome to the forum!

I'm very happy with mine. It's great on the highway. Very comfortable, my butt doesn't get sore, but my legs get stiff after we have been driving for for 3 or 4 hours so it takes a little getting going when we pull into a rest stop. :)

The 2017 models will see, nice rebates once the new body style, 2018 is available. My local dealer, had a lone 2015 platinum, siting on lot for almost two years. $8,000 in rebates, plus dealer discount, could not move it. Not many people willing to spend $70k on one. They have priced the new models, with extras, that make no sense. Then when you trade it in, they offer nothing.

My new 2017 Limited got the $8000 Ford Rebate plus 4100 Dealer discount plus $750 email from Ford on last minute discount (got night before made deal) plus $10K on a 2010 GMC Acadia with 94K. Original MSRP on Expedition ws $62K. I told my next door neighbor about the deals and he traded Explorer he had for a new XLT Expedition for his wife.
I really could not say no given my preference priorities. When I started looking on a Thursday, dealer had 3 Limiteds; Silver, White Frost, and Red. When we stopped by after a dinner out on Saturday to show my wife, the Silver and Red were gone so I told dealer Monday am we would proceed with the deal on the White Frost.
Our plan will be similar to the Acadia, long distance driving only due to crappy mileage around town and we have 3 other vehicles (including 2 beaters) to use around town that get worlds better mileage. I feel the Expedition will run to 150K if maintained, the Acadia just had too many issues that dated from its design in the mid 2000s, smoking brakes travelling in the NC mountains with our granddaughter aboard was the last straw, though it performed better over its life than I had expected, mostly as great GMC dealer took great (but not cheap) care of it. Issue with brakes was fluid was worn out, dirty. Changing it and master cylinder solved last problem-I had never believed the brake fluid changed being pushed was a realistic maintenance issue, now I am a believer.
I do not doubt Ford will increase rebates on 2017 Expeditions, but in our Southern area there are not many left other than Black 4WD units. The pricing they are putting on the 2018 Expeditions and Lincoln Navigators are staggering so they will want to dispose of any internal competition.
I believe that all the bad exhaust cabin leak publicity is hurting Ford on getting rid of the Explorers, Ford needs to address the issue-I had researched the net pretty heavily on Expedition having similar issue but nothing credible was found.

I'm sure the 18' will drop after a while. A lot of people forget consumers buy at what price they 'perceive' the most value. If it is priced at 60k dollars for a base model no one will buy it and it will drop like a rock. I was talking to a guy who bought a new Tahoe LTZ and I didn't realize how much GM would negotiate, he got it cheaper than I've seen a lot of new expys sell for. A full size SUV is not worth 60 grand any day as a base model. Mine was 32 grand MSRP in 07, today for the same truck its 52 grand MSRP. From 97-07 the price went up only about 1,000 to 2,000 dollars then from 07-17 it went up 20,000 dollars.

The 2018 has a 3.5L, The 5.4l had only slight more. What is point, on gas mileage?
Yeah but 2000 technology is very different from 2018 technology. Plus, there is also the turbochargers to factor in, and the fact that there is better gas mileage tech that didn't exist so long ago. Still, I prefer my V8. :)

The 4.6 isn't tiny compared to today's engines like the 3.5. The 5.4 is just gigantic. Huge deck height and just a bulky, top heavy (large heads)engine that has a large physical stance.

The 4.6 isn't tiny compared to today's engines. Looks like a blue whale next to a 3.5. If you've ever seen either out of their trucks. Yes the 5.4 is bigger, it's way big. The deck height on the 5.4 is very tall and overall it's a big bulky and TALL engine, but it's great on gas when geared correctly.
They used the 4.6l in Crown Vic P71 interceptor cop cars, GT Mustangs and Lincoln Town car for 18 years. They all performed well with this motor. Yes, it sucked in the Expedition. The truck version, does not have same power or mileage, no matter what it was rated at. The 5.4l was a pig on gas and not that powerful. The jury is still out on the 3.5ltt, people like them, much better, compared to 5.4L. It has 65 more hp and a couple more MPG.

The 4.6 wasn't a truck engine. The 5.4 has a way better torque curve to deliver power. 365 ft pounds is not lacking any power lol. Mine does fine on gas don't know what you mean by a gas pig. 5.4 Triton was designed to be a truck engine unlike the 4.6. The 3.5 does nothing for me I've driven plenty now. Torque comes in good and it goes but it feels blah compared to a Modular V8 when you get on the gas they don't have that roar. I like that I can throw 5,000 plus pounds behind me and not even feel it... can't say the 4.6 would do that.

The 5.4l make best power around 4000 rpm. That is screaming, foot to floor. The new 3.5l, makes power quicker, at a lower RPM. It is in its power band, were you need it, for normal driving.

I won't drive the 3.5 simply because I know of a few who have had issues with them. It's a short-er term motor IMO. Maybe a coincidence, maybe not, not for me. A truck engine is designed for longevity and power in a happy medium... the ecoboost has crazy power but won't last as long and requires more maintenance. 5.4 reaches 365 ft pounds in 3,000 rpm range and has a pretty better torque curve compared to 4.6. The 5.4 is the red line and 4.6 is pink they speak for themselves.IMG_8429.JPG

the 5.4 is what, 330CI? Kind of neat how our perspective on things changes over the years or for those of us of different ages....when I was a kid, we had three cars in our driveway...none of them had UNDER a 440CI engine with the Caddy having a 502CI (8.2L)engine.....THAT was a Gigantic engine........to me.

Still see lots of 8.2s in the new boats... Mercruiser still loves to use twin 502s for both inboard and sterndrive power. It's the only thing that will push bigger cruisers around. People complain about gas in cars... try revving twin 502 V8s at 3,500 rpm for hours on end on a lake trip now that's eating gas, then once in a while you have to open them up to hear them scream at 4,500 rpm hehehe. I agree a 330 isn't that big in the block aspect but physically the 5.4 is huge because of its OHC design and gigantic head.

My dad was into Oldsmobile Cutlasses. We had a 72 with a 350 4 bbl carb, and then a 77 with the same engine. Then dad switched to Buicks by then the engines started getting smaller.
