- Cummins High Output 6.7L
I've gotten some answers to this question before here in the forum, but so that it is clear, I want to run this buy everyone again: The latest Cummins 6.7 has a High output (HO) and a standard output (SO). The SO has a compression ration of 19:1, and the HO something like what is it, 16:1?
Now, before you answer this, you have to either own a 5th Gen SO, or know someone that does. All others please refrain.
What is the real difference in fuel economy between the HO & SO CTDs?
