The I-6 doesn't have the ultra tight tolerances where a synth is pretty
much required to keep lubrication film available. However, there is no
real reason not to go either synth or synth blend at your mileage. If
you get small amounts of leak increase you could switch brand, fix the
seals, or add a bit of Marvell/STP blend. You can extend change
intervals a bit with either swap. Might be worth checking the result by
dropping a bit of the new oil out of the pan shortly after the switch to
see if it is loosening crud--in which case just change it and the filter
until that stops. I converted to synth blend at about 45K then just
went full synth at about 70K and haven't had any leak issues other than
that cheap plastic valve cover that went away on replacement.
Do you *need* it? No, your engine was designed for the older oils and
their change intervals. Does it extend the life? Dunno--the engine is
pretty long lived on ordinary dino pee with reasonable change intervals.
Is it your engine and your choice? You answer.

Synthetic oils-Amsoil is as good as any-are a big benefit under the
most severe temperature or duty cycle fluctuations, and under extreme
stress provided the film is kept intact. The downsides are that seals
for reciprocating engines are engineered for petroleum and not
synthetic oils, also petroleum oils have superior contaminant bearing
and corrosionproofing qualities.
Engines with substantial operating time on them should always be kept
on whatever they are already on unless changing oils can solve specific
known problems-and you are willing to redo the seals. Otherwise, wait
until the engine is apart before changing.
