<VV> Castrol Syntec / ZDDP / SL

[EVERETT WILSON]

The last time I was in to the local Auto-Bone, a month or so ago, they had the 
20w50 syntec on the shelf.  I bought enough to do both vairs.

I have a bottle in hand, right now (no, not the Rum.  Why is the Rum always 
gone?)

Anyhow...

The front label on the bottle has a yellow box stating "Specially Formulated for 
Classic Cars".
The rear label has the usual blah, blah, blah about how wonderful the oil is, 
but then there are two things:

A yellow stripe in the fine print where it says: "Increased antiwear additive to 
help prevent flat tappet camshaft wear".

Then, further down where it starts to list the API info, there is a sentence 
which reads: "Does not meet the emission system compatibility requirements of 
vehicles since 1993".

It still shows API service SM/CF in the non-star circle and then API Service SM, 
SL, SJ, CF in text.

Therefore it is one of the "Energy Conserving" oils that is not Corvair 
recommended, as is typical of most 10W-30 oils aimed for the mass market 
these days.

And so this begs the question, "Is this "20w-50 classic" still the same 
formulation that is currently in the market place?"
