[Healeys] Engine Oil (cont.) - Having list trouble (again)

[Bob Spidell]

Mainly because it appears the requirement to reduce zinc and (mainly) 
phosphorous doesn't apply to 20W-50 (arguably the best oil for a Big 
Healey).  Inertia being what it is, I doubt too many companies would 
bother to reformulate any oil they don't have to (unless it's to meet 
new SAE requirements; SL, SM, etc.). 

AFAIK, no one was required to add ZDDP in the first place.  At first it 
was a competitive advantage, but was added by most brands eventually.   
Zinc and phosphorous were never reported on the bottle before (though it 
might have said something like "improved wear resistance").  That's 
changed, at least with VR1.

Note I don't profess to be an expert, but I have done a bit of research 
trying to understand the problem.  I recall reading that all ZDDP is 
made by just one company--at some point that business model may not be 
viable.
