[Healeys] Oil Additive Question

[BJ8 Healeys]

I've only scanned over the Healey Marque article briefly, but my impression of 
its conclusion is that modern oils are fine for our engines as is because oil 
technology has replaced the ZDDP anti-wear additive with something just as good.  
It mentioned a flat-tappet Nissan engine used in testing that did just fine on 
the current oil formulations.  That would seem to refute earlier claims on the 
list that old cams were destroyed quickly by using the modern oil without 
ZDDP. 
I don't believe I've ever seen an issue on the list where the more information we have on the subject, the more confusing it becomes.
