I wonder how many tanks of premium you need to go through before the effects could be measured. Keeping in mind dilution with what is already in your tank, and the amount of time it takes for the ECM to adjust fully to any changes to air to fuel ratios(higher octane means more oxygen for improved boom!).

ahhh definitely running this tank dry and trying premium cool thats awesome news enplanes why the tuner companies are able to show such a big jump with the premium fuel tunes off the stock hp values because the stock values are with reg fuel so really premium tunes should be compared to premium stock numbers

I figured that might be the case when the manual states "Fuels with
octane levels below 87 are not recommended. Premium fuel will provide
improved performance and is recommended for severe duty usage such
as trailer tow."

Retired and loving it!
Yeah, I know.....me too....
Although I will say that I towed our 28 foot TT many thousands of miles last summer on regular fuel, and up to 7,000 feet altitude on some mountain passes, and it seemed to do fine...definitely am going to have to try 91 octane for towing this summer...maybe I CAN get better than 8.5 mpg!!!
