Maybe Ford should have said for best results use premium fuel.
They did.
Then someone would say, but I don't want best results I prefer worse results when towing.
It is more like excellent is good enough. Those here that have actually tried it reported the results were not impressed with the improvement. The one guy that actually reported using 91 octane while towing said: " cannot tell you the difference."
Ford could write and entire bible on the effects of premium fuel but the average consumer would not understand all the technicalities, so they simply state use premium fuel when towing. Leaving us to proclaim premium is not necessary,ignore the manual.
As you stated a few lines up, they said "for best results". Ford never said that it is necessary except for the HO version. So now we have a Chevy diesel owner making up stuff that he would like to see in the manual for Ford gas engine owners. As I said earlier, somebody trying to justify not buying an EcoBoost. Now, please go share you expertise with Chevy diesel owners and leave us idiots to our stupid ways and quit taking over threads about Fords just to complain. I am happier that way.
