Since the advent of synthetics for consumer use (automotive) there
has been a flail about gaskets. In the auto market there are fewer and
fewer problems both as a result of using more compatible gasket materials
in the engines and in moderating the ingredients of the oil itself.
I would not use synthetics in an older engine for the same reasons (amplified)
that I would not change brands of oil in an older engine - crud releases
due to incompatibilities in the oil.
Given the previous posting, if I were you, I would get it in writing from
the manufacturers of anything in the engine compartment that touches the
oil whether there are any problems with using synthetics. If there were
no responses to prevent it, I would use the synthetic AT THE SAME INTERVAL.
This will give you very much less wear. Using the synthetic oil for a
longer interval would give you the same wear (worst case) as conventional
oil but fewer changes.
I don't own an airplane. But I use synthetics in my car and change it at
the recommended interval (or less) and am confident that when the body
and suspension is shot to hell, the engine internals will be in great
shape. :-)
