How about the VW Vanagon factory owner's manual?  That is the viscosity recommended there for all except extreme temperatures on either end.  At the high end it recommends straight 40 weight, at the low end a lighter oil, I do not remember specifically, but maybe 10 or 20 weight.

What waterboxer engines are not high mileage?  After all, the newest one around is 22 years old.
