6.4L Hemi mpg
All hwy, no trailer.
Forum Discussion
I think the key component for a 6.4 to achieve good fuel economy as demonstrated by the OP is for the engine to be able to run in the 4 cylinder mode. I suspect running into a stiff headwind or running larger tires will prevent cylinder deactivation and fuel economy will suffer.
I drove out to our deer camp last Friday with no head wind and achieved 21mpg, but driving back home with a stiff head wind the mpg dropped to 19.2 when I got home.
In addition I don't hand calculate my fuel economy anymore since the trucks computer is within .1 mpg of the hand calculated value.
