3 month study, does drive mode affect MPG? Does it matter?

Nice. seems to be a lot of variables with drive mode mpg topic. I will answer questions that people have had for me.
In eco mode, i drove about 80 interstate miles. Same as in sport mode, about 80 miles interstate. I had about 120 miles interstate in normal mode. Not to sure as percentage wise how many miles i drove.
Another comment pointed out the disparity of mpg difference week to week in various modes. I noticed that as well!! I do not know why the difference was so big. I figured maybe the software was making adjustments to the engine after seeing that I drove in the same mode after a period of time? I had no big swing in weather or trips or driving styles. I did see that and still do not know what the difference was, every fill up, once the nozel popped off, I was done putting gas into the vehicle, i did not do the top it off with as much fuel as I could get into it.
I am defineatly looking to get a tune for towing. I just have a big question. Is a tune worth it without changing exhaust, intercooler bigger cai box and so on, or will a tune serve my purposes just fine. I see a lot of Ranger owners using the unleashed tune.
Eco mode, really was a big disapointment. do not know when this mode would do better. i did think it would make a difference.
the terrain I drove in is south texas. it is flat as can be down here. the biggest and steepest hills here are the levees. wind always blows from the southeast, so the only interstate here goes west to east, so if you get the wind at your front coming, you get it at your back going. so it kind of evens itself out.
I had a constant air pressure of 38 in my tires. that is what the placard on my Ranger calls for. Me normally though, run 34 just to soften the ride. or even 32. but it has been at 38 since I started this big experiment.
I am sure there is a lot more I could have made notes on had I done this more scientiffically. but unlike a denver 100 loop, i was trying to see just what would happen with drive modes and mpg over a real everyday use of a vehicle. So this reprresents, at least i feel it does, a true real world representation of everyday use of a vehicle. not perfect conditions the car manufactures test in. Once I start working on a regular basis again maybe I could do this again. But then we throw in the towing and hauling that throw in the monkey wrench to perfect testing again. But that is real world use of the Ranger as a working vehicle, so I just may do it again once I am working 100 percent again. right now I am only doing light work 3 or 4 days a week.
I think I will begin that test in another month or 2 again! as a work vehicle and note all the drive modes utilized with the eco, sprot and normal modes being the main mode the vehicle drives in. Stay tuned. I would keep closer to 500 miles for each mode and use the same 93 octane gas and same tire pressure as the placard says.

ECO is too sluggish in hilly areas. flat areas at highway speeds it ok......but I dont like the slow throttle response.
SPORT is great on the highway. feels great,peppy, and powerful, but NOT for city driving.
NORMAL is my daily driving mode (when not on highway)
your mileage may vary :sunglasses:

I recently drove across country in my 2025 Ranger. Thinking ECO mode was the way to go. Forgot one day and starting getting like 27mpg in Normal. I really don't see the advantage of ECO. Sport for in town driving just too much. But in North Dakota on those straight 80mph highways wow!

ECO mode doesn't exist on the Raptors, we have the following:

1. Normal
2. Sport
3. Tow
4. Slippery (aka for snow / icy conditions)
5. Off-road
6. Rock Crawl
7. Baja

So, I would say Normal is the closes thing a Raptor has to ECO and kinda what we consider "eco mode".

I typically use Normal for driving around town and it works well for that, but I prefer Sport Mode for on the highway due to the better throttle / transmission response (mine is Pro Cal tuned, so 455 HP / 536 lb-ft), unless I end up in stop and go which is rare. I don't see any difference between normal and sport in highway driving since 95% of it just cursing in 10th gear in either mode.

Slippery works well in you guessed it, snow / icy conditions, but I also find it useful for cold starts in the winter as it dulls the throttle response making it easier to keep below 4k RPM and lightly modulate the throttle on a cold engine in winter.

Off-road works great for general off-road uses on trails, fields, dirt / gravel roads etc, but it does like to stay out of boost in off-road mode, seems to be tailored more towards slower speeds and throttle modulation, which is nice and also it actually helps with fuel mileage when on trails.

I spent 4~5hrs of off and on driving around an OHV park in off-road mode and only used a half tank, it was all slow speed stuff but staying out of boost basically makes the 3.0L like an NA V6, you don't need power for speeds of 15~30 mph driving on rougher slower terrain.

In normal mode, my last tank of gas I got 17.8 MPG from my raptor with a bit of hooning around (not much, but occasional pulls on on-ramps, merging and back country roads), but mostly country highways in the 55 mph range, for a Raptor that's pretty decent, especially a tuned one.

Thank you for sharing! I'm a bit of a data hound and track every fill-up. I also experimented with normal/eco mode over several tanks never found a consistent bump with eco.

I use "normal" mode most of the time and am sitting around 20.3 mpg lifetime average.

Just to say how little I used eco, I went into forscan last year and removed it from the list of available choices. I added everything except Baja, since I don't have awd available

I have pulled a 6k travel trailer in the long rolling hills of the south, alabama, Mississippi, and the flat lands of texas. I can say, when i ran in 8th or 7th gear, with higher rpm. I got better mpg and ran cooler than running low rpm in 9th gear. Weird, with the mpg anyway. But i can understand how high rpm runs the engine and transmission cooler.
But i definitely run in tow mode when pulling or hauling. I run 60 or 63 with this rig. Lots of wind resistance. Any faster i get 8mpg.

if you drive 60 on a flat road, no wind, you will definitely see a difference between sport, which will be in 7th gear, and normal or eco in 10th gear, For mpg.

at 70+ all modes are in 10th gear. But sport mode will downshift quicker when you step on the peddle.

I actually prefer normal or eco on the freeway as I am generally maintaining a speed and don’t want to be down shifting all the time with small inputs on the gas pedal.

and sport in the city, not to accelerate, but because it has better engine braking so I can use the brake less.

They work okay. The wind did not move them around much either. I only had to adjust the passenger side once on a 500 mile trip.
