2017 3.5l ecoboost Expedition, any known issues?

[Muddy Bean]

Never had a $100 fill-up in either of my Expeditions. Computer indicates well over 15 mpg for the life of the truck including several hundred miles of towing.

What car are you using premium in? The Expedition doesn't need it. (I know you know this. Couldn't resist. )

Chuck,

I’m towing a 5000lb trailer through the mountains. I absolutely need to use premium in my Ecoboost. Makes a world of difference

Premium 'recommended' for towing and advertised HP/torque. Reduced power on 87 octane.

I've only had my 2017 for three weeks, but in that time I've towed a 6,600 lb trailer 2,000 miles and took a road trip to New Orleans from Houston with six passengers. So far so good. It was a used rental that I purchased from Carmax with 58K on it. MPG towing is only 8.5 - 9.5 depending on grade and what type of truck I'm tailing. But that's to be expected I guess, with my trailer size (27ft Forest River). So far so good. We avoid driving the vehicle around town due to the poor fuel economy. But for road trips, it gets the job done. I think my minivan was more spacious, but of course it couldn't haul 7,000 lbs.

The up side to rentals is that you can be fairly sure that the vehicle was well-maintained. The down side is that many people beat on rentals. Thinking about it logically though, most people that rent an Expedition aren't driving it like a sports coupe.

A friend of mine had had a '17 Expy rental for a month or so while his company van was being replaced...he beat the snot out of it like a sports car and put on 10K miles. LOL

Says a lot about a person who beats the snot out of a rental.

Experience varies and I've yet to see the need for any octane higher than 87. Perhaps those Michigan Mountains need 93 octane with a 5000 pound trailer but towing the same weight trailer with both 87 and 93 here in the PA, WV, and VA mountain I don't see or feel any difference with the '17 truck. Only a couple of tows over the mountains with the EcoBoost but it's quantums better than the 5.5 V8 in this role even burning 87. Maybe this is coloring my experience.

I have the 3.31 axles in the '17; 3.73 in the '07.

I easily saw a 40% increase in fuel economy when I switched from regular to premium in my 17 EL. Plus was 20% over regular, premium resulted in another 20% increase over plus. Any forced induction engine needs the octane to keep the tune sharp. Sure you can run it on regular fine but the power is down. More power means less throttle needed hence the added economy.

Canada, it’s $1.15 per litre which is 4 litres per US Gallon =$4.60 per gallon. Our gas prices fluctuate from $1.05-1.30 per litre.

Mine was also a daily rental, I bought with 16,900 km on it which is approximately 10,000 miles, I’m at 22,000 km now.A few years ago I used to own a 2004 Yukon XL with the vortex engine and I got better fuel economy.

I realize my expy is heavier than my 2.7 l f150 and the f150 had a larger tank. I am going to switch my computer over to us units of measure and will report back what my mileage avg is.

Okay here it is, I get 13.9 MPG US
My 2004 Yukon XL did better. Just saying

You mentioned getting a bit over 15mpg since new.....too bad we have different axles since I use nothing but 93 and have a 3mpg delta up but with 3.73 gears....we'd need a geek to run the calcs to factor that out.

interesting....

We don’t have mountains in Michigan. I’m rubbing a 13,000 mile tour right now and I’m out west for half of that...literally california, Arizona, Oregon, Washington, all over. And yes they actually have some serious mountain passes here.

It's indisputable the 3.5 EcoBoost has more power AND gets better mileage running higher octane than 87. Perfect is the enemy of Good Enough which, for my applications including a 5000 pound trailer crossing the eastern mountains, 87 octane is Good Enough.

93 octane stays 60¢/gallon more expensive then 87 octane here in Richmond. The differential never seems to change. (My other car requires premium unleaded so I'm painfully aware of the price difference!) 87 is about $2.25 this week and 93 running a little high at $2.97, or 33% more expensive. To run this all the time would only be economic if it produced the same 33% more miles per gallon which ain't gonna happen so that eliminates the "economy" advantage.

Nice to know there's extra power available albeit at a substantial cost increase. If needed.

Remember when each grade was 10¢ higher than the previous?

Yep. Those were the days.

Getting 17.5 around town in the 18 Expy, 3.73 gears and tow pack. Got 22.0 on a recent trip running reg unleaded with cruise at 65. My Silverado V8 gets almost identical numbers but is lighter than the Expy also.

When I first started driving in '68 gas stayed at .25 per gallon. I would put in 4 dollars which was 16 gallons in the GTO and could drive close to 5 days. When the embargo hit in '73 gas jumped to .75 per gallon and everybody freaked out, and I got a '65 Beetle to drive. I miss the days of full service stations, "fill er up", and got the windows washed, tires and oil checked, AND the attendant always said THANK YOU PLEASE COME BACK. Now when you pay for gas you're lucky if the employee even looks at you while you pay for your gas and it's an odd day when they say THANK YOU........

Nothing to do with this thread except the gas...When I was a kid (born in '54), my parents had a "Rollfast" tandem bike. A bud and I would ride that to the local gas station (about 1 mile away) for boat gas. The kid on the back seat would carry the 5 gallon boat can, and it was heavy and awkward on the bike. Never made the news though, always successful. Oh yeah, $.28/gal or so...

I'm torn between the V6 in the newer models and the V8 in the pre '15's. I still like the V8 and it seems to be the best for my budget. I'm going from a 2004 Tahoe LT with just under 200K to an EL. Under 100K for not more than $20K is my goal...

If your buying out of warranty and running it to or past 200k I’d go with the 5.4L V8.
