No. It's not a 'deal' of any proportion beyond the 3% fuel consumption increase.
Buying 85 octane and trying to boost it to 91 octane would cost a fortune. Those off the shelf cans increase the octane level at only .1 per bottle.
You'll gain nothing by using grades higher than the Jag recommended 91 octane.

So you discount additives like "race gas", Torco accelerator, and Royal Purple Max-boost. I can tell you there are a lot of not great gas options. Living in Colorado it is very hard to find 91 octane with no ethanol gas and forget 93 octane. So for me I have 3 options.
1. buy premium with ethanol
2. Buy 85 octane without ethanol(12 minutes drive out of the way)and add one of the above.
3. Buy 91 octain with no ethanol is about 15 minute drive.
Price goes up a fair amount as you move down that list. So opinions on what is best and is ethanol gas that big of a deal to these engines?
Thanks

Yep, I'm with Stohlen and Unhinged. ....it can't be stressed enough that the canned octane boosters are a complete waste of time and money.
While ethanol is fine is regular use in our cars, it does degrade more quickly than non ethanol fuel and since my car sits for up to 6 months at a time and I'm lucky enough to have several sources available, I use either Chevron 94 non ethanol or Shell 91 V Power non ethanol. YMMV

This is only a factor with 'vented' fuel systems (boats, garden tools, some motorcycles or pre-1970 cars). Modern cars have sealed systems eliminating direct exposure of the fuel to air. Degradation of ethanol fuels under such conditions is similar to non-ethanol.

We've been over this; short answer is that I don't believe you. Even "sealed" systems still have air in them ....and even if I was wrong, you can't give me even ONE advantage to running ethanol contaminated fuel.....ergo, I'll continue with my non-ethanol choices.

The amount of air in the tank has a finite amount of moisture in it, I'm sure you'll agree. That moisture will be absorbed over a period of time and suspended in a harmless manner by the ethanol in the fuel.
Not sure if that's not a better situation than the same amount of moisture remaining suspended in the air space above the fuel when using pure gas.
If the gas tank was vented directly to the atmosphere, then you'd be right to avoid E10 during storage. I drain the tanks of my gas powered vehicles/tools etc. that are so equipped.
