Any benefits to high octane
Are there any benefit to running octane gas when towing? I had heard when towing use high octane gas.

Just a comment since I'm not sure exactly what you are saying:
There is no sensor or computer in the vehicle that measures octane in the fuel directly. What it measures is what happens when the fuel burns: the oxygen sensors in the exhaust and the knock sensor mostly.
So.....if the knock sensor reports "all quiet on the home front", putting in fuel with a higher octane rating accomplishes EXACTLY NOTHING.
Now.....the exact composition of the fuel might make a difference if the other sensors see something different, in the exhaust gas for instance, but that is NOT because of the octane.
