Does EcoMode Actually Save Fuel?

[@williecaguana1020]

Eco mode is honestly for people who wake up super early and can drive slow on the right lane, regular mode does just fine. Trust me I’ve broken my head figuring this crap out and it’s a waste of time

[@mcmuskie2563]

Agree

[@whynotcnc8828]

i use eco mode, runs great

[@poppyneese1811]

My 23 F150 2,7 4wd 3.73 rear does a lil better than 20 around town and about 22.5 on the highway when you check it at the pump, the MPG meter lies like a rug always about 1.3 mpg optimistic! Great Video!

[@rockreverb]

Thanks for this test . With my F150 2.7 ecoboost I always had the impression that it was more economical in normal mode rather than in eco mode. Your video shows the opposite thank you

[@tacomaken15]

I have a 21 f150 crew cab. Took a trip to south Carolina from Central nj. Total of 3 people on truck and packed bed. Couldn't get any better than 25.4 mpg. The further you go in ecomode the higher you will get. This was on cruise at 68mph.3.5l 10 speed transmission.

[@roadrunn3r92]

Nice! That’s some great MPG!

[@SergeyPupkoMusic]

Dang, must have been a very flat road... Any hills would kick in the turbos and boost = bye bye fuel.

[@SeriusQne]

Thanks a lot man, this helped me make a decision if I should use Eco mode during my first distance trip in my new Malibu

[@Mr371312]

Driving comfort is affected because eco mode tries to delay downshifting as much as possible. So when you pass the shift threshold it tends to downshift unexpectedly, causing rocking.

[@chrislancaster1982]

I wouldn't call that comfort. That would fall under performance.

[@thestranger1164]

Omg, so that's what that is.

[@jhagen4850]

Let's apply a little high school physics to this problem. When you're driving at a constant velocity on the highway what are your sources of drag? Mainly rolling resistance and aerodyanic drag, of which the latter will certainly be larger. So what is the power required to stay at this *constant velocity*? Well, the power will be the combined force of tire resistance plus aerodynamic drag. While the atmospheric conditions persist (i.e. no change in wind, temperature or air density) this will not change, which is to say that the force you're required to overcome will not change. Since power is the dot product of Force and Velocity if you're not accelerating your engine will have to generate a specific amount of power on the highway to continue at constant speed. This power will be the power previously described plus any mechanical loss in linkages. So the question is this: does eco mode help you while you're driving at a constant velocity? Why would any sane engineer design an engine to generate a specific power output sub-optimally? Which is to say, if I need to generate 40hp of power, why would I design an engine to run consuming x + 1 units of fuel per second when it can be designed to consume x units of fuel? The point is you're fundamentally misunderstanding the point of eco mode. These turbo engines are designed to deliver large amounts of torque and power. You'll probably notice that despite being turbo charged they don't actually have high compression ratios - naturally aspirated Mazda engines actually have significantly higher compression ratios. That's because they're optimized for torque and not efficiency, which would result in higher compression ratios (but lower maximum torque). So your eco mode will limit this engine advance *for the same throttle position sensing.* What does this mean? If you drive in eco mode and don't change your driving style your engine should accelerate more gently and generate some fuel savings. But it's just a mapping. If you compensate for shifted mapping by giving the engine more throttle you will likely negate any benefits. Now there may be some other things going on that I'm exluding, like advancing cylinder deactivation at lower power levels, but in general this is going to be the case.

[@anthonyhales4192]

Just tried eco mode on a 2 hour 30 min drive for the first Time. It is a huge difference in power. Throttle feels lackey, almost like that button turns the boost down on the turbos. Which is fine. I averaged 22.4 without a reset. I just bought the truck and only have 500 miles on it. I did not reset the trip.

[@georgepintye4752]

Very good video tackling a subject most truck owners ignore; their vehicle's fuel efficiency. I recently traded my 2017 2.7L STX for a 2020 with the 3.5L and 10-speed. Eco Mode does help with mileage, but it basically deactivates your turbo boost, and I mean completely. I actually wondered if it may not be become a safety issue if you find yourself in a split-second decision on the highway, but find that you can't engage the vehicle's acceleration because of the limitations of the mode. It also plays with the way the transmission shifts, and not in a good way. What is an extremely smooth shifting transmission normally becomes very herky-jerky in Eco, especially at lower speeds. After 600 miles, I think it does help save on gas, but there are clear trade-offs that aren't going to be worth it for most folks.

[@SergeyPupkoMusic]

Deactivates the turbo boost? Nah... Driving along on, cruise control, on eco, and when a hill comes up I hear those babies sing the song of my people. I think all it does is reprogram the throttle response and changes when the transmission shifts. But if I step on it it drops a few gears and turbos turn back on. At least that's how it is on my 2020 3.5.

[@markkropf8295]

Nope mine makes the same boost in eco as in normal. I just have to use slightly more throttle input.

[@lappydog9020]

2020 platinum and believe ot or not i get 2 mph better on the highway in eco

[@rasanchez169]

Imma do this test when I drive from abq nm to Las Vegas nv. And see how it does. I'll be doing the 5.0 version with mud terrain tires

[@roadrunn3r92]

Cool! let us know what your results.

[@ThatBoyMichael1]

How was it?? I literally have the same setup

[@palaiyotist]

wind also affects MPG as well as I seen that on my Ford Focus as i got 46 MPG and 500 miles on freeway with wind 11MPH pushing me (michigan to Tennessee I-75)

[@blisphul8084]

2:25 As a hypermiling Ford Maverick Hybrid owner getting 50+ MPG in optimal conditions. (Managing about 70 in a couple recent short back road trips) that number was shocking to see.

[@blisphul8084]

To be fair though, getting 50+ on the highway is a combination of skill and luck. 70+ on back roads definitely requires precision and knowhow, which comes from experimentation.

[@JLynchJr86]

Eco mode is terrible for the highway. I just drove 1100 miles, all of it on eco mode. My MPG went from 17.9 down to 17.1.

[@mcmuskie2563]

Agree

[@GgRae-gv1tg]

Turbo is not used as much and it shifts up quicker skipping gears. Also fuel mapping is milder.

[@deedeethomas5322]

I have a 2020 Kia Sorento and i watch your video to see which drive mode was better for gas..

[@danhaley4465]

Eco mode on the highway uses more fuel than regular mode. Tested it yesterday. 235km used 340km fuel in eco mode. In regular mode it used 220km 😮 I dunno

[@mikejimenez1617]

Thanks for running the test.

[@richardleetulio7441]

so the question do we use it or not..??

[@HajunAdventures]

It just seems like econ mode on my car limits my rpm. I see how that could help me to burn less gas. But if I'm taking longer to reach my desired speed, doesn't that end up burning just as much gas? Not to mention, the italian tuneup helps keep your engine clean.

[@walkawalka4ni9]

No, accelerating faster uses more fuel. Think about sprinting vs jogging.

[@mcmuskie2563]

Ya I’ve ran 350klm to the cottage numerous times trying to keep it real. Not much of a difference at all. Eco might carbon it up more also.

[@paulyman34]

Thanks buddy great job. San Anto baby!💪♥️

[@defaultlmk9290]

It seems to improve it significantly slightly 😀 so signifacant slight improvement is essentially same as no improvement

[@dominicl99]

Thanks for running these tests so I didn't have to!

[@Tango247]

Well I am not convinced. I have a 3.5 dual turbo but I am also leveled and have added 20 inch custom wheels and 275/65R20 Terra Grapplers. I also have a bed box and other gear so conservatively I have added 250 pounds of weight to the equation. I also have the 36 gallon tank, so when full that's 80 more pounds. Basically my weight to HP ratio is going to be way outside of what I suspect the factory used to calculate. I just did a 400+ mile round trip, flat land, with "down" in ECO and "back" in normal mode. Almost all but a few of those miles on interstate. Full to start in both directions. I was also driving where I was passing a few more than getting passed and trying to run about 78 mph on cruise when traffic allowed. Yes, there were some jams and slow downs in both directions. End of story: 17.4 MPG in ECO and 17.8 in Normal. Yes I understand my speedo is off due to tire diameter but it still showed ECO wasn't as my truck is configured.

[@rndmvideoz]

Did you change wheel size in Forscan for the 20's? That will affect it if you didnt

[@echopoint8817]

I have a 3.5 EcoBoost and gets on average two more miles per gallon in eco mode

[@mcmuskie2563]

I agree, although it’s not as much as everyone thinks.

[@aaaideas4U]

Forums have all said in order to achieve 24 mpg you have to stay 55 mpg and under.

[@CWLim-so8vd]

Hi. So which mode u are using now? Eco or comfort? Or sport?

[@leojohnson9410]

I use sport, not to be stupid but when you need to put your foot down to over take or avoid and idiot it’s so much better

[@GhostOO9]

Do you think you’ll ever do the longer test?

[@markkropf8295]

Unless the trucks computer makes changes to the timing and fuel air ratio eco mode won't make any difference in a constant load condition. I don't think it does. I think what eco mode does is it trys to save fuel in 2 ways primarily. 1. Decrease throttle response. This hopefully makes most people accelerate slower and minimize any waste. 2. Lower shift points. This saves some fuel by keeping RPMs lower when driving in conditions when you are going through the gears. When you are cruising at 70 RPMs will be the same in the top gear.

[@codylucier4688]

Obviously you dont know how it works. The technology in cars and trucks is insane. It used less fuel makes less boost and certainly saves gas. Why do you think it gets faster when u out it in sport mode. It ads fuel and boost to make more power. Te hnology is crazy now a days

[@codylucier4688]

That's the beauty of fuel injected. It's all computerized

[@Chuckers84]

@@codylucier4688 actually Mark is 100% correct. It only changes the throttle mapping and shift points. When it’s in sport mode the throttle response and shifts are quickened as well as it stays in a lower gear longer. Thus getting the sense of more power and in turn loosing fuel economy. As well when you are in Eco mode the throttle is deadend and the shifts are sent up to a higher gear sooner thus giving it a slow sluggish feeling. Where the eco mode shines the best is in the city and acceleration is applied and not at a constant speed scenario like the highway.

[@allynonderdonk7577]

Ecomode started destroying my Honda Odyssey. The cylinder that shut off started building up carbon and scoring the cylinder from unburned stuff in the cylinder. Better mpg but a third less miles out of the engine.

[@poppyneese1811]

Ford doesn’t deactivate cylinders on the Ecoboost engines, pretty much transmission shits and lessens throttle response.

[@michaelsullivan5195]

Eco mode just means less aggressive shifts lower rpms instead of higher shift for power but it is a truck if you can afford the payments why worry about gas😂

[@alfredomercado8517]

What gas do you use ?

[@ChicoM16]

Eco is okay I wouldn't use too much especially In a 4 cylinder car it would mess with the the emissions first would the catalytic converter and oxygen sensors the lack of power could clogged the system

I didn’t watch the entire video so what’s better eco or normal in terms of fuel economy?

[@yonggeun4222]

normal

[@kbomera87]

@@yonggeun4222 Actually read about this, eco mode does save fuel however it depends on a number of factors. Like terrain, climate, load, speed. For example on a high way its much better to use normal mode than eco mode. Eco mode = less power output {the video would have been much better if eco mode was explained. The explanation he offers a vague.
