You may experience loss of performance, heavy spark knock (knocking from engine which robs power and may cause engine damage) and eventual engine damage if the heavy spark knock continues.

i know a person who run regular in a premium only sports car 1 tank 3 broken piston rods plus the other internal damage.

Also the worst part is along with what littlehorn and papa have said is that if there is damage, and there is a warranty on it, it will be void and you will be left holding the bill (my bro is a sevice manger (toyota/Lexus), and this has happened on a few FG's. but i do beleive that th 05 Acura has "spark enchancment" DON'T quote me on that, you will have to check your owners manual (if you dont have one, call a dealer). but you can run reg but the car will not preform as well as with what it was designed for. A friend at work has a 04 (he loves it) and he can run either, which is good seeing I live in Canada and gas is $1.10 a litre (or $4.20 a us gallon)
