Fusion Ecoboost Fuel Mileage

[timwil56]

I'm waiting on my 1.5L and currently drive a PHEV. When I had my 2.0L Escape (which I wish I still had, oh well, I thought electric was the way to go), in summer I was getting about 25-27 mpg's combined hwy/city and averaged 32, but got as high as 38 with some wind assist on long freeway trips, in winter around 22 combined. So you're right, 20 seems low under "normal" conditions. Maybe a fluke or bad gas.

Hi zip89105,

Actually based on your description you really did not do that badly...

Only 1/3 of your trip was on the highway, and the rest not.

From what I have read the 2 litre ecoboost is not as good as the 1.5 for fuel mileage but has significantly more getup and go.

On the trip I just reported about, 80 per cent was on the highway.

When I left the highway in Guelph in under 50 kilometers the car had lost more than 4 mpg from its initial average.

By the time I got back to London it had only regained 1.4.

@timwil56

The 1.5 or the hybrid is the best all around motor for mpg in my opinion, but I wanted the HP. The 1.5 negative, once again my opinion, is you might get start/stop in 2017. Ford should do what Chevrolet did to their Malibu and go with turbo motors only. I had a long trip recently and my best tank was 31mpg US, meanwhile the 2.0 egoboast carved through mountain passes with ease. The vehicle is relatively new with very low mileage so I hope to see another 1 or 2 mpg increase soon. I was just surprised as I hoped my worst tank of fuel was in the past, not the future.

[morry]

According to the Dealership in Canada for 2016 the start/stop was an option. I made sure I did not get one with it!

I actually wanted the start stop feature and that's why I went with the 1.5L. It improves the mpg's slightly, depending on driving style and can be turned off when not wanted or needed. After driving a PHEV for the past couple of years, I'm going to have to relearn how to drive when my Fusion arrives. In the PHEV, you're constantly trying to extend battery range and coast, regenerative brake, start very slow and switch back and forth from EV, Auto and Engine, it's kind of a PITA. I have learned to really squeeze every mile per gallon though. I'm pretty light on the accelerator and usually get better than the EPA estimates in my vehicles. The C-Max Energi was rated at 88 eMPG and I consistently get 115 eMPG, although in winter it drops to about 80-90 eMPG. Once my Fusion is broken in, I expect to get 27-28 city and depending on speed limits, 38-42 highway. I drive to AZ and back every Jan/Feb and this year, with a little wind assist, the Energi averaged 36.8 to and 38.4 back, using all ICE.

For the last few weeks the weather in this part of the world has not been very good for reporting mileages so I didn't really have anything to add to this thread.

This last Saturday was probably one of the best I am likely to see for this and the results were very good.

I set the cruise at 72 mph as usual and for the first few kilometres saw 34.6 mpg (14,9 kpl). By The Guelph exit it had only dropped to 34.1 mpg (14.6 kpl),

By my destination in Guelph it was still showing 32,7 mpg (14.1 kpl), and by the time I returned to the 401 it was down to 32.2 mpg (13.9 kpl).

By the London exit it was back up to 32.7 mpg.

I think that this will be one of my best runs for this car because the weather couldn't get much better than it was.

The air temperature was about 60 F and there was no wind the entire day. You hardly ever get it that good in this part of the country.

This meant that the air wasn't needed and we didn't even have to open any windows.

When you remember that all the EPA mileage tests are done at much lower speeds and don't REALLY allow for air pressure or wind speeds I think this car is definitely getting the "expected" results.

One other observation; while I did sometimes see higher numbers for the first part of this trip you can bet that was due to the very strong tail winds that you can get in this part of the world. Notice how much the numbers dropped once I was out of it!

This time everything was quite constant. It is quite interesting to see how much of an effect the weather can have on your results.

First 10,000 mile average (calculated) overall = 33.74 MPG. About 80 / 20 highway (speed 72 mph in CA, 77 mph in AZ).

Average range between fill ups 417 miles.

"Average MPG" read out is 0.8 MPH higher than actual.

Most recent 4000 miles (approx 6000 to 10000 odometer) = 34.20 average MPG

Fuel -- 87 octane regular.

So today I have some more stats to share...

There is nothing really special to report. In our part of the country summer has finally arrived and for my last two highway trips, of about 320 kilometers in total the daytime highs were in the low to mid eighties. Yes the a/c was definitely on.

On the same tank of gas I also did just over 180 km in and around the city.

I re-set everything in the trip computer on my last fill and this time I used 41.1 litres for 506 km.

The straight math on these figures gives a mileage of 12.3 kpl or 28.78 mpg.

The trip computer displayed an average of 12.4 or 29.0.

Although there is nothing really great here it does confirm that the onboard computer is accurate enough to be trusted.

Also remember that my normal cruising speed for these trips is about 72 mph.

The EPA specs for my car claim 24 city 36 highway and 28 combined and even with the A/C on and cruising well above 55 mph, I am having no problem matching their claims

Getting much better mileage on the 2.0 these days. When I was running stock with a stock tune I was lucky to get 20-21mpg with mixed driving (Boston area with traffic and a commute into the city). If I tried hard to save gas I could get it to 24 on a good day. If I decided to drive hard I could drag the MPG down to 17-19.

 

With mods and a tune I am now running 22-24+ mpg consistently. I can even be rougher with the car than before and still get this kind of mileage. I have not tired to do a max it out yet but I bet I can do better than I have in the past.

[akirby]

Are you running a 91 or 93 octane tune?

[MightBeASynth]

Are you running a 91 or 93 octane tune?

 

93 Octane, still dialing it in, on the 4th revision at this point.

[tonyvdb]

I have a 2015 2.0 and have been getting 28 to 29 driving in town and some highway. Haven't been on a trip over 50 miles yet.

[akent36]

After a 350 mile road trip which included country roads, small towns, gravel roads, getting lost, etc, etc, we still got 33.8 MPG with our 2016 2 liter ecoboost. Very satisfied.

[nForrest]

2016 FWD 2.0 Ecoboost, 21-22 MPG, city driving and about 20 miles a day. I also punch on the interstate for the 6 mile run, when traffic allows. I have only had he car since December 2016. I have only made a one highway trip from Shreveport to Dallas, and got 31 mpg both ways.

 

Another thing that has some impact is, that around town I am usually I in "Sport" mode, while on the one long trip, I was in "Drive".

[vishnubysani]

....Ford Fusion 2015 Ecoboost SE 2.0L

 

I am getting 16-18 only ...95% city driving ... Not sure whats wrong I am doing ......

[zip89105]

My 2.0T also gets poor city mpg. My last tank, mixed driving (mostly city), was 19.6 mpg, and the fill-up before that was 19.9 mpg. You're doing nothing wrong. The 2.0T isn't a gas miser around town. I bought mine for the horsepower, not the mpg.

 

Edit: I live at 2000ft elevation and my air conditioning is always running this time of year, none of which is helpful for mpg.

One thing that helped my gas mileage a little was changing from the cheap brand to a Top Tear Brand Gas. After running a couple of tanks thru, I went from 20-21MPG to 22-23 mpg. Not a big improvement, but enough to notice. Also, noticed a marked decrease in particulate discharge on my chrome exhaust tips.

[mattri]

Just ran over to Iowa City for the game this weekend. Total trip was a little over 300 miles, mostly 75mph interstate with some 2 lane highways and more stop and go traffic than I care to admit. Overall agg was 36.5 out of a 2017 SE with the 1.5 running cheap gas. Not too shabby.

[CRU66]

I bought my first Ford (2015 Fusion Titanium AWD 2.0 ecoboost) about 6 months ago and I must say I'm rather disappointed in it for multiple reasons - gas mileage being one of them.  I bought the car used with only 8,000 miles and it still looked and smelled like a new car.  The car was a Ford executive's car (he didn't drive it much) and no accidents as far as I can tell.  The original sticker for the car was still in the glove box and it stated 22 mpg City and 31 mpg Hwy with an average of 25 mpg.  About 70% of the driving I do is highway so I figured I would at least get 25 mpg but was hoping for around 27 mpg average.  I checked my mileage at every fill up for the first two months and while the onboard computer was saying I was averaging 25 mpg it just didn't seem right so I started doing the math myself.  Sure enough the onboard computer was off anywhere from 1-2.5 mpg and always NOT in my favor.  So I was averaging about 22-23.5 mpg and again this was mostly highway driving.  Pretty bad for a 2.0 turbo in my opinion.  I have taken the car on two long trips since purchase and the most I saw (only one fill up) 29 mpg and that was all highway.  I estimate the actual mileage closer to 16 mpg City and 27 mpg HWY for an average of 23 mpg.  I have taken the car to the dealer and complained about the mileage but they didn't find anything wrong and just blamed the poor mileage on the AWD.  Also, I live in northwest Ohio and it's pretty flat here (no hills or mountains) so you would think gas mileage would be decent here - I can't image what mileage is like in areas that have mountains.  BTW, I have owned several other cars (Toyota, Honda, GM, etc.) that have onboard mileage calculators and all of them have been spot on except for this Fusion.  Never have I seen one off by 2.5 mpg except for this Fusion.  I just feel like Ford is lying to their customers.

Nobody is lying.  The EPA mileage tests are very stringent.   Ecoboost engines have a wider range of mpg than naturally aspirated engines.   You can get better mileage if you drive the right way but you can also get worse mileage.

 

Find a level stretch of highway and set the cruise control to 55 or 60, reset the mpg and let it go for a few miles and report back.  If there is a problem it could be anything from a dragging brake to a lazy O2 sensor or even bad gas.

 

Also - are you sure it has the OEM tires and wheels?  Do they match what is on the sticker?   Have you checked the tire pressure?

[Thomas R]

2014 1.5L. Got up to 38 mpg on the freeway... until I hit L.A.

Get 27 mpg mixed driving.

 

[CRU66]

akirby, as for your questions...

 

"You can get better mileage if you drive the right way but you can also get worse mileage."  - I'm a 50 year old man who drove a hybrid before this car so I'm not a teenager beating on my car.  I am and drive like an old man so I don't know how I could get better gas mileage by my driving habits unless you suggest I start beating on my car?  I've gone so far as to use the paddle shifters to force the car to shift to the next gear before it does on it's own (trying to keep the rpm's down).

 

"Find a level stretch of highway and set the cruise control to 55 or 60, reset the mpg and let it go for a few miles and report back." - As I stated in my original post...the computer reports better gas mileage than what you are actually getting so your test wouldn't even be valid.  According to the computer my car is averaging 25 mpg but if you actually do the math (miles driven divided by gas used) you get a lower number every time by 1-2.5 mpg.  The highest I have ever gotten was 29 mpg and that was 100% flat highway (65 mph) driving (gas station exit to gas station exit).

 

"If there is a problem it could be anything from a dragging brake to a lazy O2 sensor or even bad gas." - I would hope that the dealer would've checked that out when I complained to them?  Wouldn't a lazy O2 sensor cause a bad idle?  If not, how would I diagnose that?

 

"Also - are you sure it has the OEM tires and wheels?  Do they match what is on the sticker?   Have you checked the tire pressure?" - Yes, as I stated in my original post...I bought the car with only 8,000 miles on it and it does have the original tires and rims.  I have checked the tire pressure multiple times.  So far I have put 9,000 miles on the car for a total of 17,000 miles but there has been no change in gas mileage.  The computer is still 1-2.5 mpg off from the actual math and I am not overfilling the gas tank - once pump stops, I don't keep trying to fill it more by "clicking" the pump handle.

[akirby]

I don't have a clue how you drive - I'm just putting facts and options on the table.  You don't have to "beat" it to get bad mpg.  I've found one thing that makes a difference is taking your foot completely off the gas when coasting.  Keeping just a slight pressure on the pedal prevents the Deceleration Fuel Shutoff from engaging.

 

Just for fun - try fuel from a different station to make sure you're not getting lower octane than advertised.  It can happen.   If that doesn't make a difference try a tank of premium and see if that makes a difference.   Also make sure it's E10 and not E15.   The EPA tests with pure gasoline (not E10) even though most of us can't find pure gas any more.   E10 will lower mpg versus pure gas.   E15 will be even worse.

 

The test is perfectly valid and it doesn't matter if the computer is off a little.   The point is to see what you're getting as close to EPA tests as possible.   If the test says 27 mpg that points to a problem.  If the test says 33 mpg then it's probably your driving.

 

Don't assume the dealer did anything.  Dealers are independent businesses not controlled by Ford.  Some are great, some are terrible.  If those other tests point to a problem you can always try a different dealer.

[drolds1]

Hence, the statement, "Your Mileage May Vary" or YMMV, which has entered the American lexicon and is now used in a variety of instances that have nothing to do with EPA figures.

 

As akirby points out, knock 3% right off the top for E10, which is mandatory in many places.  More.

 

I've never been a fan of small engines in big cars as a path to fuel efficiency.  I believe that sometimes a bigger, more powerful powerplant doesn't have to work as hard thus produceing better real-world mpg.

 

Case in point: attached is a shot of the fuel economy readout from my 2017 MKZ 3.0TT taken on a trip this past summer.  This was taken while cruising on the NJ Tpk at the speed indicated and A/C running.  I was able to maintain this for the entire highway portion of the trip.  Including stop-and-go at the beginning and some local driving at the end, I averaged 26+ mpg for the entire 94 mile journey.  This is a 400hp/400lb.ft, 4300lb AWD sedan.  Before you bring up the accuracy of the fuel economy gauge,  I've checked it against the old-fashioned, hand calculated method numerous times and the results have always been within .1 mpg of each other.

 

Lincoln doesn't even use the "Ecoboost" name anymore.  It's just 2.0T or 3.0T.
