Default 87 octane or 89 octane in hemi?

Newbie here with a new '07 QC 4x4 hemi.

I have seen info on the hemi wanting 89 octane. Is there any truth to this? any benefits seen?

Where I live, 89 runs around $.09 more than 87. I am wondering if I need to be paying the extra???

Thanks
John

You might want to do a search on this topic, there are probably a dozen threads dedicated to it. FWIW I notice a slight difference when running 87.
