[AT] oil for old engines

[Ralph Goff]

Heres a rather disturbing bit of reading regarding modern engine oils and 
how they could be harmful to our older engines. Apparently the new oil lacks 
zinc, manganese and phos? or something.  ZDDP is the abbreviation. Read all 
about it at

or http://www.naaaccc.ca/oil_additives_.htm

I think I'll consider changing over to diesel engine oil for my engines if 
this is the case.
