Higher octane gas does nothing unless the engine has a higher compression ratio and will knock or have the spark ******** by the engine computer under load. Octane is not a measure of btu from a gallon of gasoline but rather its resistance to pre-ignition when the fuel enters the hot cyclinders of the engine. Pre-ignition results in the engine computer retarding the spark advance and this reduces the power output of the engine. Putting high octane rated gas in an engine than it was designed to use accomplishes nothing for the engine but does help increase the profits of the oil companies.
The 89 Octane is a "plus" in that it is rated higher in terms of pre-ignition than regular 87 Octane gas. Octane is also not linear so mixing 1 gallon of 93 and one gallon of 87 octane gas does not result in 90 Octane but a mix closer to 92 octane in terms of pre-ignition.
Poorly done test. The guys should have driven both trucks up the grade at 55 mph using cruise control and then noted the MPG with each. They also do not understand how Tow Haul mode works as it is designed to keep the ATF cooler but keeping the torque converter clutch engaged longer between shifts and nothing more.
No evaluation of engine braking going down the grade which is even more important than MPG going up the grade.
