I have a 2016 F-150 Eco-Boost. In 2017 I carefully monitored my fuel consumption over numerous tanks of 87 and then 91 octane and recorded fuel consumption both towing (30 ft TT)and not using an app (aCar). I can't remember the exact data but I was able to determine that there was a definite improvement in consumption using 91. I then compared to increase in cost (expensive fuel here in Canada) and calculated that there was little difference in subsequent cost with maybe a slight advantage to the hi-test. As a result, I've only used 91 in my truck since. Of course, if my driving habits were different, the results may be different. I'm pretty light on acceleration and tend to slow gradually rather than brake hard.
