You make a good point, and it puzzles me as well. I 'think' but don't
know that
those engines are manufactured with superior cylinder wall finish and
probably
piston rings engineered for this -- but I'm only surmising it.
However, I built one TR4 race engine in which I put synthetic oil at
startup, on
the advice of a person who worked for a major oil supplier. The rings
never
seated, and it caused a teardown and rebuild. So I reverted back to
starting
rebuilt engines on regular oil, getting the rings seated, and then
switching to
synthetic.
By the way -- talk about modern engines -- a number of major
manufacturers do not
start their engines up prior to turning the key at the drive-off at the
end of
the assembly line. Honda started it and just blew away the other engine
manufacturers with the cost reduction -- and Honda engine longevity and
reliability is pretty darned good.
