We've got a just broken in (around 3,000 miles) NW Connecting Rod 2.1 in
our '84 Vanagon and I'm leaning toward running a synthetic oil in it.
I'd appreciate any thoughts on this.  In particular what is a good
synthetic: Redline, Castrol, Mobil, Amsoil?  Are there real differences
between them?  What grade of oil to run?  The Redline web site seems to
suggest that it might make sense to use both a narrower viscosity range
and a lighter high end.

If you're running synthetic how often do you change it?  Do you do
filter changes between oil changes?

My goals are engine life and, hopefully, a bit more fuel economy.

Thanks, Doug
