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

Just like Ford and GM, Chrysler recommends premuim fuel if towing. I would think the 6.4 will be the same. Recommend and require are totally different things!

Can't speak for GM or the earlier Ford's but premium is not required for use, trailer towing or not, for the current Ford 6.2:
"Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. Some stations offer fuels posted as Regular with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended."
Not in the manual but apparently the engine will make more horsepower with premium.
