[Mgs] [Mgb-v8] Kendall Oil

[Stephen West-fisher]

Of course, all those flat tappet engines before the late '60s did just fine
with .08% or less ZDDP :-)
And one of the current oil tests for the standard is how well it performs in
a V6 flat tappet engine.

That's just not correct, it's like saying if 0W/40 fully synthetic is right
for high-performance modern engines it must be good enough for ours, which
is
definitely *not* correct.  There is more than enough evidence out there from
*owners* that modern, low ZDDP oils cause problems, see
http://www.ttalk.info/Zddp.htm and http://lnengineering.com/oil.html#Z13.
The
fact that you can quote sources that say SM is fine, and I can quote others
which say it isn't, just goes to show how confusing the whole subject is.
It
is a fact that modern Diesel oils have a higher level of protection, and so
conform to the earlier petrol grades, precisely because Diesel engines need
more protection for the little ends than SM can give, similar to flat-tappet
engines.
