Hi I have a 2015 f150 xlt with a 2.7L 6 speed. I noticed that I do not have the eco mode feature, just the tow and sp mode. Can I it be incorporated on my truck? Thanks

 

10 speed Trans have enough close spaced gearing to make use of the 1-3- 5, 6 skip shifting at low road speeds and light throttle.
Don't think 6 gears is enough.
The gearing spread is not enough and involves softer Throttle sensitivity changes used in the 10 speed program.
Look up both Ford Docs Pdf and read the gearing spread between the two units.
A large difference that would not be practical.
For instance, 4th jumps right to overdrive gearing 5 and 6 in the 6 speed.
While gears 8, 9, 10 are all, overdrive in the 10 speed with all the lower 7 gears to do the pulling from an engine that has spare Torque to do it..
Good luck.

 

No. it’s a 10 speed only feature.

 

I also believe that it didn't show up until 2018. I had a 2017 3.5 with 10 spd and it didn't have the eco mode.

 

Thanks for the information. I wish that instead of skipping a gear like on the 10 speed, Ford would make the eco mode on a 6 speed shift sooner on light throttle on no load. I noticed that the rpm is around 1800 before shifts. I just go this truck with 50k and I am getting between 22 to 24 mpg. Changed the oil at 6k and it was black. Going to change it maybe at 4 or 5K next time around.

I would ask you to be reasonable / practical in thinking about shift points.
The engine has to be turning fast enough to >make enough min. Torque for acceleration to pull the vehicle weight before up shifting.
If this were an EV there would usually be no shift application required based on motor Torque.
This is why there are min speed shift points programmed into the model design and application of the vehicle. The points are determined by factory testing and not all left up to just throttle application. The 10 speed has its own controller for Trans operation with the required data points coming from the PCM 'calculation of loading.
If a throttle application point is reached, the program will keep it in that gear or downshift from a higher gear if you apply more throttle above a certain min.
An example is driving in highest gear and suddenly throttling up for more power for passing that requires the Program to skip one or two gears so enough engine Torque is available to move the vehicle at a fast enough speed to make a safe pass.
This is where the reasonableness comes in. Not just for fuel mileage but also safety in use.
Best that can be done for fuel mileage is use a light foot, keep tires hard and weight to min.

Good luck.

 

Thanks for the detailed reply Bluegrass.

 

um oil is supposed to turn black, its by design
… oil has 3 jobs: 1 lubricate 2: absorb heat 3: keep the engine internally clean

if it doesn’t turn black … your engine is gonna die.
Dont believe all the mumbo jumbo that the engine should have a cleaner run through it because of how black the oil is…

 

I find the eco mode sort of pointless for my driving. Around town, it's annoying to use in traffic. On the highway, it doesn't make much difference when I'm driving hours at a time in 10th with the cruise control engaged.
