Do you think I would see any difference in gas mileage or performance going from a 91 octane with 10% ethanol to a 94 Octane with no ethanol added? The price is about 3 or 4 dollars more a tank. Good idea?

My guess it won't make much difference unless you're pushing the car to very high limits of performance- like you're racing on a track. Try out a tank of the good stuff on a road trip (less variables) and see how it works versus your normal range with 91. Remember you would need to get an extra 20-50 miles per tank to actually save money on this proposition with the good stuff.
On an average commute, you'll probably be ahead simply saving your money and buying the 91 which meet's Acura's requirements as-is. If you do decide to do the experiment-please followup with your results.

Eliminating the ethanol alone should increase your gas mileage, I'm not sure how much. I use ethanol-free gas now and i've seen my gas mileage improve nearly 10% consistently. On the other hand, it costs 10% more so it evens out.

Ethanol free gas has not been an option in the Chicagoland area for atleast a decade. Hell, I dont even know what that is anymore ;-)
Rule of thumb is generally ethanol will cause your mileage to decrease thats just a given fact however as mentioned in order for it to be beneficial your going to have to see measureable gains and I personally think youd be surprised at how minimal the differences really are. It wont hurt to try so I say go for it but your going to have to be as consistant as possible between the tanks otherwise any differences cant really be used as even the outside temperature makes a difference in fuel economy.

Well I think I'll give it a try, I generally get between 440-450 KM per 53 or so L. I drive a mix of highway and city driving. I'm thinking either way it can't hurt. It's only 3 or 4 dollars a week.

Ethanol has about 70% as much energy per gallon as gasoline so at 10% ethanol you'll have about 3% less energy per gallon and at least a 3% drop in fuel economy. There are other factors that go into it as well but it's worth trying the "good" stuff for a few tanks to see if it works out in your favor.

Premium here in OK is 91. They did away with 93 few years ago. August of last year I started going to a station that sells ethanol free gas and my mpg increased by 4mpg and I do 90% city driving. I now average 23 city whereas before it was 19. Its usually around .20 to .30 higher at this station since it's ethanol free. Well worth it in my opinion.
