Doesn't seem insignificant to me when all that's separating two moving parts is a 1 micron thick film of oil, as can be found in places in the engine. In those boundary areas I'll take any reduction in friction from an EP additive I can get...

Appreciate if you care to provide link(s) on the diamond thing and its mechanism ?
I believe the Ti additive interacts with the metal (not the oil) at these high pressure/temperatures area to form a sacrificial layer between surface asperities, thereby reducing friction.
Typically this contact in surface asperities (boundary area) occurs when the MOFT has broken down. In effect, the EP additive is your last defense against metal to metal contact.
