Everyone, thanks for your input!  I learned a lot.  It's a project I'm
going to do, as I feel it will help with longevity of my 2.1L DJ-code
engine.

In regards to experience with synthetic oil, I used it in my '85 Westy
which was my daily driver from 2000 to 2004.  I put 65K miles in that
period, many of them flying down the interstate at 75mph for 12 to 14
hours at a time.  I never had or saw any problems, but I didn't have
an oil temp gauge to see just how hard I was pushing that engine.
Yes, it made it well past 189K miles with original heads and head
gaskets, but I don't think I'll be taking the same chances now or
driving my current Westy that fast despite the 112hp.
