Rick,
I use Mobil 1 and have been very happy with it. Here are some articles about long term testing.
Longevity test:

Fleet test:

With a very expensive motor, I would rather be safe than sorry. The additional cost of synthetic oil is minimal in the overall cost of owning a Cobra. I would be very cautious about the informal test mentioned by jschiller, while I respect the test effort, IMHO it has too many holes in the monitoring/testing procedure and an inadequate baseline.
