I started moving away from premium gas when i had my M35 and gas prices were going up daily. I used 89 octane and am still doing so with my 2008 G35. Absolutely no ill effect. I'm not sure, but I think with 89 you would have the equivalent of 1/2 tank 93 + 1/2 tank 87.

I have a 2005 coupe with 35,000 and a 2007 35x with 39,000 and have used nothing but 89 grade. Have never seen a drop in performance or mileage. I haven't tried 87 unless my wife, bless her heart, is trying to save on gas money. If she has I never noticed and difference. The coupe get 24.5 on trips and 18.5 around town and I'm a hot dogger. The 35x gets 23.5 on trips and 17.5 around town.
