This is a topic that has been discussed to death and I think the consensus is it won't hurt to put a lesser grade gas in your tank, you just won't get the optimal performance. For example, I can definitely tell the difference between 89 octane and 93 octane in my '04 MDX. As for the '07, I haven't had a chance to try that experiment since my wife stole the keys.

The Acura will run on the lower octane(87), but runs best on 91 or above octane. Using the 91 or above is probably a better option because of 2 reasons:
#1: you get the optimum performance . I also noticed smoother operation, and slightly less noise.
#2: you get more miles to the gallon. I own an 04 MDX, and I tried to run it with 87 octane , and it ran just fine, but I got only about 11-13 miles per gallon in the city, and 14-18 miles per gallon in the highway. So on a full tank of gas, I ran only 218 miles!! On the other hand ,using the 93 octane, I got about 16-19 miles per gallon in city, and you won't believe this, but I got about 20-26 miles per gallon in the highway!! So a full tank of gas took me some 326 miles(with some gas to spare).
 
I recommend you to use 93 octance, or at least 91 octane. You shouldn't use the 87 octane because after all, this is a car costing upwards of 40 grand. I mean, this is a tuned V-6. My 1997 camry (V-4) uses the 87 octane, so most of the time, 87 octane is required for small cars/SUVS.
