I've heard from several members on the board that using a bottle of EOS on my first startup (Gen I SBC) and 500 mile OCI will greatly help the motor. I just recieved my two bottles from gmpartsdirect.com and on the back it clearly states (in all caps) "GM recommends E.O.S. assembly lube only for the specific purposes listed above. GM does not recommend the use of this or any product as an additive to engine oil."
Can anyone clue me in a little more here?
