89 is fine unless you tune it for a higher octane

The stock tune is written for 87 octane. Higher octane fuels will not gain you any performance on the 4.6L unless you're tuned for it. About 75% of the forum members are running nn-OE tunes. Custom tunes and CAI combo should be your first mod if you want about 20-25 RWHP gain.

I use 91 in mine, because the owners manual suggested it.
