Varmit-forget the Rotella-T. "Mark has told James a fable.
There is nothing in any oil to 'counteract' oil consumption. Especially what you've got-1 qt/150 miles. Even cement wouldn't stop that.
Instead call Mark and ask if Roush is using 'low-tension' rings on the pistons. And ask what the piston to wall and valve guide clearances are. The motor obviously has too much clearance machined in.
