Bronco sport fuel milage

[wireman]

2023 round trip from SoCal to Iowa and back. 2021 Badlands 2.0 using ACC when possible.

Obviously varied terrain from mountains to flatlands thru Nebraska. Includes 1 week of city driving in my hometown.

Actual calculations for 4,189 miles were 26.9 MPG. My trip 1 meter showed 28.6 MPG for the trip, a 1.7 MPG difference from actual calculations.

Traveling 70-75 MPH on the Interstates.

Another 2023 round trip to Yellowstone and back. 2683 miles and actual MPG was 26.8

I get 29 mpg around town that‘s both in normal & eco mode in Long Island NY. I’m pretty happy with that. I’m pretty aggressive too I press that medal. In my opinion that 1.5 l does very well. Coming from a Vulcan 3.0 Taurus wagon I was doing 21 mpg around town. That Vulcan is a great engine still going with 243k hope the Dragon does as well.

Didn't know that higher octane fuel would give such a bump. All in all I'm getting 40-50 more miles per tank.

I've tested premium vs regular extensively; I've never gotten better fuel economy using premium. You can view my post on the subject here. This link opens a spreadsheet with all my data. I've made the switch from one to the other a couple of times at different times of year to control for temperature and formulation. I suspect something other than switching to premium has affected your fuel economy. Perhaps cooler temperatures has reduced your use of air conditioning.

Yeah I mean I’ve seen both sides where people say it doesn’t effect mileage and people that say it does. (Nothing of substance just individual experience) I don’t believe I have been using the A/C any less than I usually do. In fact last week I would say I used it more due to the crazy heat wave we had down here. to your point there could be another factor that I’m missing though but I’m not sure of what it would be.

Here's my logical reasoning against the idea that higher octane can improve mileage: There is no more energy (measured as BTUs) in a gallon of premium than there is in a gallon regular, therefore to increase fuel economy the PCM must do something with the way it manages the engine.

What exactly does the PCM do when you use premium fuel? Turbocharged engines produce a lot heat, which can lead to detonation at high power demand. Higher octane fuel requires greater heat and pressure to ignite, so when burning premium the PCM can advance ignition timing and increase boost (under certain conditions), affording higher maximum horsepower. At lower power demand, however, the engine doesn't produce enough heat to require the use of premium, so ignition timing can be set to whatever value achieves best economy.

If someone understands this better than me I'd love to hear an explanation of how premium can improve fuel economy. I've been asking this question for a number of years on several different forums, and no one has provided a satisfactory answer.

I wish I was the guy that was smart enough to give you the science but I am unfortunately not. Just giving my individual experience.

We are getting 28.5 mpg. We just returned from an epic road trip. We purchased 174.9 gallons of gas, ranging from $3.99/ gal (89 oct) to $2.54 / gal.

Tier 1 regular fuel for me, mainly Costco for the value.

No idea how people manage to get crazy high mpgs above the EPA rating estimations. I have the 1.5L engine and I have a lifetime estimate of at or slightly below 25mpg driving mostly in the suburbs with some very occasional highway trips here and there. This is on par with the EPA estimated values. Are you guys only resetting the trip meter when on a long downhill stretch of highway to get such high numbers?

nope then I would be up over 80mi/gal. I reset my trip 1 and average when I get fuel and they stay left alone till the next fueling. I have almost no difference in normal vs eco mode as my trip is all highway with a 110 - 120kph (65-70something mph) speed limit, aside from a 6km stretch with 6 traffic lights that 50mph

 

[Jenma]

Filled the tank about 45 miles freeway at 60 to 70 mph.

 

[REDWM]

With 10020 miles, we get around 33 miles per gallon driving in Eco mode most of the time. Ecp does fine driving in the country.

 

[Jenma]

I should have added the 33 mpg was in my Badlands, Falken tires, normal mode, sea level, at about 70 degrees.

I have a '22 Big Bend and I drive an average of around 31 miles per day. Two thirds of my daily mileage is highway. I run 93 octane fuel. I am not a drive it easy or an every light is a drag race driver. I like to get to speed quickly and settle in. I have 235/60R18 Continental tires. I don't do hand calculations. The mpg on the dash is close enough for as much as I care. And it shows 28.4-28.6.

We recently took a trip from the Rochester NY area down to Legoland in Goshen. I reset trip 2 when I fueled up. Most of the trip was highway at 73-74 mph through the hills of Central NY, North Eastern PA and the Catskill Mountains. On the way down I started around 32-33 indicated, but by the time I drove home we were right back at the same 28.5 I see most of the time.

I have a question.
Sometimes after the BS has set for a while, such as overnight, when I crank it up, it shows slightly less on the mpg readout than when I had switched it off. Sometimes as much as 1 mile per gallon diff. My 2018 F150 I traded in for it was always the same.
