If you read the owners manual ECO stands for Economy. Which tells you the engine had gone into Multi Displacement from 8 cylinders to four.

Yup its like a game try and keep it at 20 mpg for me anyway.
That may be true for the hemi with mds (I'm not sure if it is or not but if you saw it in the manual then ok), but the 4.7L doesn't have mds....it simply is a sign that you're driving efficiently (high vacuum....low engine load)...
