Lucas Oil Additive & a Fresh Motor????????

[Mr. Chevy]

I finally got my Chevelle motor squared away and she is back in the car and running good!! I used Brad Penn "green" break in oil to break in the cam and ran the motor for about an hour with same in it and then changed it. I then put in conventional Castrol 20W50 motor oil and have driven the car approximately 200 miles.

My question is, I would like to change the oil again now and use the Lucas Oil additive (1 quart) with the Castrol conventional 20W50 oil in the motor. Will this hurt the motor?? Should I allow the rings to seat and break in more before adding this?? I went to the Lucas website and they claim you can use the stuff on a new motor. Has anyone had any issues or problems with this stuff?? All I have heard is good things about this additive..

Thanks... Rich
