I've always switched all my cars over to full synthetic, even ones with high mileage, and have never had a problem of any sort.  There was something posted here once about the very first synthetics causing problems with seals, but those days (and formulas) are gone.  Your results may vary.

there any special precautions I should take when making the switch?  The van
doesn't currently leak any oil and I haven't had any oil pressure troubles,
I would just like the extra protection that the full synthetic claims to
offer.

Thanks in advance.
