This could actually be a good thing...

same old formulation that we want, with tons of zinc, but if they change the "application" to assembly lube only and NOT oil additive, then they don't need to take the zinc out to meet current EPA requirements on modern cat equiped vehicles.

Yes, it may be a good thing?

I’d just be a little cautious when going against manufacturers recommendations. If you decide to chance it, you’re on your own.

And, there’s always the old hot rodders adage, “If a little is good, then more is better.” Or is it? If you’re using a motor oil with a good known level of protection additives already blended in, then why worry about additives?

I reason that burnishing a new cam a lifters together for the first time is one application, normal engine operation is another. That said, I’d use the Engine Oil Supplement for the intended break-in use, drain, then add a motor oil with good ZDDP levels, and sleep soundly at night.
