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

From my experience quite a few engines that require premium fuel will still run just fine with regular fuel albeit with slightly reduced performance.
I believe the ECM (on most premium fuel engines) simply adjusts the timing accordingly when it senses any pre-ignition from the use of regular fuel.
