I talked to Zach about the same issue. I ended up going with the Lucas break-in additive, it has quit a bit of zinc in it. 5000 ppm in 4.5 quarts is what they advertise, so 2200ish ppm in 10-11 quarts. You want atleast 1500+ IMO, and thats not counting what is in your oil already. Plus the Lucas is easier for me to find over the counter locally. Most any O'Reilly's or Auto Zone has it, I think its $12.99 a bottle.
