Where did you get this information? Can you share it. Yes I’m asking you to prove this statement.J Gibbs Driven BR30 Break In oil (regardless of it's Zinc & Zddp content ) has probably the Lowest Functional Anti-Friction wear protection package of Any commonly available motor oil & Least camshaft--Flat Tappet friction wear protection.....It's Lowest wear protection rating Will likely permit any new parts fit dimensional irregularities be most agressively self-clearanced wear mated in of all available motor oils & Least protective of Camshaft--Flat Lifter wear....If that's what you're looking for on first start up,... that's the oil (best friction in a can) product to use...
I started using Joe Gibbs driven racing oil and break in oil on the 90’s on advice from a great local machinist/drag racer. Everyone using it has had zero problems. This includes new engine break in and decades of street operation and drag racing on various vehicles.
