fuel grade

RE: fuel grade
It is fine, I dont beleive it will hurt the engine unless it runs below the 87 grade level, but the manual recommends 91+ octane. If I am wrong please someone correct me.
From the manual: The recommended gasoline octane rating for your vehicle is 91 aki / 95 ron. Do not use any fuel with octane ratings lower than 87 aki / 91 ron otherwise expensive engine damage will occur. Your vehicle may also be operated by using unleaded regular gasoline with a minimum octane rating of 87 aki / 91 ron. However, using 87 aki / 91 ron octane fuel will lead to a certain loss of engine power.

Audi recommends 91, but no lower that 87, im really just wondering if 89 might cause problems after constantly using it for a long period of time, thanks for your input, and I suppose i should just play it safe with 91
