Explorer Gas Mileage - including Ecoboost

[Professorfingers]

For the performance I get with the 3.5 turbo, I am very happy. No sluggish zones, just step on the gas and it goes. And the tranny works very well, as well.

JMHO,

I'm using Petro Canada 87 octane after finding no difference using the 91. On my last fill it read 324 miles to Empty. In 50/50 driving I'm averaging around 21.1 mpg (Imp) or 17.5 (U.S.). Also still using Winter gas and running Winter tires, until next week that is.

I'd be happy with your numbers and hoping maybe by accumulating a few more thousand miles to get the car "fully" broken in.
I've pretty much stopped WOT and generally only get up to 3500rpm+, when making a pass; otherwise it's always under 3000rpm.

From what I have noticed with Ford vehicles, the trip computer takes at least 3 fill ups and ~ 1k miles before it starts showing the correct mpg. Even then it may be +/- 1mpg for what I have noticed. That is why it is always best to do manual calculations.

The biggest driving changes I have made that seem to make the most difference:

1. Driving 5 mph slower than the stated limit (can be tough in some instances to do, but for the most part I make it happen)

2. Excess idling (I work in the city and cannot avoid this at times)

3. Slow take off and anticipating stopping (again, can be tough to predict)

Speed is greatest killer of fuel mileage and the thing drivers have the most control over.

True that...

I filled my tank yesterday and the computer said I had 395 miles to empty. It has slowly been rising since I purchased the EXP. I now have ~2400k miles...I like seeing this go up...Last calculated MPG was 20.6. Now it looks like the actual versus the computer is ~.5mpg difference. Does anyone really know what the reserve capacity is? I know the fuel tank says 18.6, but not sure if that is the full capacity or there is a reserve beyond that.

For tuned Diesel engines, "boost" is the fuel mileage killer.
If you can run your engine without making unnecessary boost, you will achieve the best mileage.
Once you start demanding power and boost from the engine, the fuel mileage goes into the toilet.

I am sure gasoline engines react the same.
Like Peter said, speed kills mileage because the greater the speed, more boost is needed to maintain.
So, stick to 65 and use the CC. Keep the boost under 5lbs and it should produce numbers close to standard V-6 mileage.

Check page 174 of your Manual and good luck trying to figure that out.

About 1.5gal after the gauge is completely empty and DTE says 0.

Yeah I read that earlier today and that's why I asked....

So is that part of the 18.6?

Yes.

Hi, I bought used 2015/8 (2016 model) Explorer Limited 3.5 V6 (290 bhp) couple of weeks ago and car is otherwise very nice, but gas milleage seems to really poor. I know that way of driving, stops and all different factors affects...

But, no matter how nicely and smootly I try I can do only 13 mpg.... which seems way out of the average based data I see from other Explorer drivers in Fuelly.com

Car has still bumber to bumber warranty left, but for making diagnostic easier I would like to have list for the service things they should look at. So are there know issues in Explorer which could cause bad mpg?
What are most common causes etc?

 

[Mr. Alligator]

13 mpg at what speed? City? Highway?

Are you sure it's not 13L/100km?
13mpg is about 20L/100km and that is horrible for an NA v6.

Welcome to the Forum.
Your thread has been merged with this one on the same issue. One of the biggest influences on gas mileage is SPEED. Also ensure that tire pressure is up to specs.

I am getting about 19 highway....and 13 city (live in downtown Boston...so i average about 15MPG a tank)

 

[LMC122]

I've owned a 2014 sport with about 65000mi for a few months now, and no matter how easy you drive it 16-17 mpg is it, maybe 18 on the highway with cruise control set on 70.
Previously owned a xlt v6 awd and averaged 20-21and was able to get 25 all highway. I understood the sport was going to get less then my xlt but it should do better the that.
Is there anything to check or look for. No check engine light, fresh oil, new air filter, and tires at 35psi. As far as i can tell it drives good plenty of power.
Even with cruise control on 60-65 it struggles for 20mpg. Has to be something, ive read plenty of post an articles of these getting 22-23 on the highway at 75, and 19 mixed driving.

Spark plugs getting worn?

I've only got 3400km on my 2017 Explorer Sport. My computer says I'm getting 18.7L/100km (12.5mpg) and I have never reset it since new including break-in. In any case, the number is close enough to my actual economy, as I've been recording my kms and liters filled up. Only using premium (91 octane). Also it was 18.5L/100km when new, and hasn't diverged significantly.

Almost all my driving is city driving in stop and go conditions (Vancouver BC). And recent winter conditions, I've been driving around in winter mode which has me at about 21L/100km for localized last fill up.

I do tend to accelerate more than the average person when I'm at the front during a red light, just because it's still so fun. I also generally drive in Sport mode because I like the throttle response better and feel the normal drive mode throttle programming has issues. I definitely wouldn't suggest keeping it in Sport mode for any fast cruising above 80km/h (50mph).

If I drove in an economical pattern, I don't know if I could beat 17L/100km in my city commute conditions. It's 30km round trip each day.

I have noticed with the 3.5L V6 Ecoboost, it is quite easy to flood the turbos with gasoline, if you happen to gun it at just the wrong time (cooling technique). When this happens, you'll feel significant turbo lag, almost like the car is about to stall out for nearly a second before it suddenly lurches forward with insane power, and likely crucify your economy. The trick is in the correct timing and pressure of acceleration. Haven't quite mastered it yet, but I'm getting better at it. That's why driving in Sport mode makes it easier to avoid. My only tip so far is don't ever suddenly floor the acceleration if you already moving. Only do that at a stand still. If you want to quickly pass someone while moving, then accelerate at about 50-75% force until the power kicks in. Again, mostly just a feel thing.
