[Mgs] Re,: Kendall Oil (ZDDP)

[Steven Trovato]

The argument I have always heard is that old cars were built with 
larger tolerances, so to maintain oil pressure and get the oil to be 
everywhere it has to be, the 20W50 is better.  On a new modern car, 
where all the tolerances are much smaller, much thinner oils are 
appropriate.  I'm not really volunteering to defend this logic.  I'm 
just saying that it is what I've always been told.
