Engine Break-In Oil do's and don'ts by Total Seal

^^^ LOL Long story short that I get from it is that Driven and Lucas break-in oils are the ones to use. I've been using Lucas for years for break-in, no problems here.
I goop the cam with goo. lol and use VR1 for break in. never a problem.
back in the late 70's I broke in a 557 solid with wheel bearing grease. lol
I guess with all the new metals .lol special oil is needed.
