, Toyota only got on the "synthetic" bandwagon when they started branding
the stuff under their own label and now they require it to keep the
warranty valid for some vehicles.  Go figure.

  Maybe BP or Shell bought out Toyota (using their Petty Cash account) and
decided to mandate the use of their most expensive oil....

   "It's Just Business..."  (a joke)  Maybe they made a deal..Toyota...a
kickback from Big Oil in return for putting that clause into their warranty
requirements...I've come to realize that anything is possible when it comes
to making money (for the Shareholders)

   Most of Vanagons were built before Synthetic Oil even existed.   I don't
see changing over to full synthetic would make much difference on anything
except maybe a Bostig or a Subie powered one...
