Default Re: 5.7 versus 4.7 fuel economy
Hi all,
I have a Dodge Ram Hemi q/c and I get 19 hwy when cruising at 70-74 mph and baby it along. The 5.7 gets better than the 4.7 when you ease it along. I usually get about 13.8 to 14.9 combined mileage but I also drive it fairly hard. I have an 07 Crewmax ordered and I wouldn't consider anything but the 5.7 in it. Most Megacab owners wish they had the cummins over the hemi in those trucks.
