[Healeys] Engine Oils

[Healey Bruce]

I spoke with Dave at Red Line last week.  Red Lne 10W40 synthetic contains 
around 1250 ppm of ZDDP.  All oils meeting API SM standards (the current) 
have between 600-800 ppm.  I also spoke with David Nock, who uses Red Line 
10W40.  The viscosity of this oil is equivalent to a mineral-based 20W50, 
according to both David N and Dave (Red Line).  Bottom line seems to be that 
if it meets API SM standard, don't trust it in an old flat tappet engine.
