I'll tell ya, medic.. the hemi get better mpgs than the 4.7 does, so be thankful that's what's in it..mileage-wise, teach better driving skills, slow down on the highway, no rabbit starts/stops, etc.. They aren't known for their mizer-ness, from the get-go..

The Hemi is very finicky about having the spark plugs changed at the recommended interval and use only Champion plugs. They will look like brand new when replacing but from what I have read and heard can make a huge difference in engine performance and mileage.I have read very mixed reviews about the programmers for the hemi, overall there have been few reports of improved mileage.
