[TR] Greenish oil now 50weight?

By who?  The factory manuals said 40 weight or 20W40 (Practical Hints 6th
ed), only if temperatures were above 70F.

Not necessarily.  Viscosity grade says nothing about the additive package.
You can buy non-detergent 50 weight (which also lacks the other additives,
like ZDDP).

Of course, it might be Paul lives where it is somewhat cooler than Temecula
(projected high today 94F).
