If I am feeding a sub panel from breaker in main panel with #4's can I use #8 ground? In the main panel I have a 3P 70A breaker in the main panel feeding the MLO sub panel.
#8 Ground

Your right. I know. EGC it is.as many years as you have been posting here, I can't believe you used the word "ground".....
"ground" is earth ie: dirt.
equipment grounding conductor ?? grounded conductor (neutral) ??

THank you. So how do you come up with that? Which NEC section?
It should be based on the OCPD not the phase conductor size?

Yes slow down! Once you have the correct terminology for the conductor, in this case an EGC, then it's easy to find the correct table.

CU or AL on the EGC?
Pretty sure we're all assuming CU.

It's not. That just where they put the table in the code book. If you look at section 250.122 it will reference the table so the location of the table within the book might not even be on the same page.
