I e-mailed Valvoline, and they promptly supplied a spec sheet for Racing Synthetic:
5w30
kv100=10.8, kv40=61, VI=170, TBN=8, FlashPt=223C, Pour Point=-42C, CCS=5200, NOACK
Looks kind of light on zddp content, but has more than an SM oil. In fact it is SL. TBN seems good for a gasoline engine. The NOACK number is higher than I have seen for other oils, which are mostly less than 11%. Maybe it will lead to high oil consumption.
The 20w50 version does have higher phosphorous content at 1300ppm. This is more of a traditional Valvoline Racing oil number for P.
