I've been looking at some data I've kept in an old spreadsheet for different oils and noticed this one for Ravenol RCS 5W-40. I believe I found the VOA on Oil Club RU a while back.

Flash Point °C (°F): 246 (475)
Pour Point °C (°F): -57 (-71)
cSt @ 40°C: 93.9
cSt @ 100°C: 15.03
Viscosity Index: 168
HTHS: 4.26
Sulfated Ash: 1.3
TBN: 12.5
NOACK: 5.70%

Calcium: 2752
Magnesium: 14
Phosphorus: 796
Zinc: 939
Molybdenum: 74
Boron: 85
Tungsten: 136

It has no approvals, since this is a race oil. Thoughts?
 
very high TBN for a "race oil".

I would say this is what oil would look like if you were free to blend what you like for excellent results, and not be totally concerned about cost.

The calcium is high enough that I wouldn't use it in a T-GDI engine.

That was what I was thinking. Also, I forgot to include the link to their webpage: Ravenol RCS 5W-40

Yes PAO synthetic as the analysis numbers selected, but I'm not 100% sure what Ravenol means by USVO technology, I'm assuming it's mPA and AN

The 10W-30 I'm using is similar in concept. It's better suited to T-GDI.

USVO means they don’t use VII or they use extremely stable VII to avoid and prevent shearing. I would. I Assume a 5w40 has some polymers while a 5w30 may not have any at all.

Ravenol has VMP and VST that are similar but lower Ca. VST is API SP and VMP I think has around 1700 ppm.

Check out their updated RSS 10W-60. They claim on the .de site that they have made a 10W-60 with no VM somehow. Oil club DE says it's got a ton of mPAO but still.

That calcium level was normal in API SN and older API specifications.
Well engineered engines won't have an issue.

In my understanding RCS is a thicker and high SAPS brother of RUP
(mid SAPS, it comes with BMW LL-04, MB 229.51, formerly VW 511 00,
Porsche C40 and A40 before).
I use to run RCS on my old 930 (no daily of course) for several years.
OC every two years, way below 5000 mls.
That said, I'll run REP 5W-30 (BMW LL-04, MB 229.51/52) on my Mini
Cooper soon again. More expensive, but higher flash point and lower
Noack compared to M1 ESP. Maybe I should run REP for the GTI as well,
but I prefer to run something VW 504 00 so far. And: $$$ . . . .

I'd opt for RUP 5W40. It's a no-VII race oil with approvals.

"Due to the special mixture of synthetic, highly polar Group V base oils with a high proportion of high and low viscosity PAO, it could be formulated without the use of viscosity index improvers"
