Rams new 6.4 HEMI
Anyone own a HD Ram truck with the new 6.4 Hemi? Looking for some real world experience with the new Hemi. Can't seem to find one on dealer lots. Thanks

I would love to know if it really needs Premium or not, as the cost between Reg. and Premium really adds up when you're getting about 10mpg while towing!
I posted the owners manual page in this thread which states the 6.4L hemi only requires 87 octane. I just downloaded the manual from the RAM site a few days ago so I assume it is up to date. Even the 5.7L hemi doesn't require, what I consider, premium (91/93 octane). In fact, my 2005 5.7L hemi owners manual specifically states not to use premium gas since there are no gains for using it. Is says 89 preferred and 87 acceptable for the 5.7 (not 6.4).
