Highest SSI VII available to blenders

[Projects]

Are there any current API approved oils using a VII with a SSI over 35? Who's VII additive is it?

Good question, but since formulations are proprietary I have no idea how we would find that out.

I would also be interested in any VII's SSI's under 25 being used in PCMO & HDEO's also. Anything that's outside of the norm. I'm not looking to link it to brand names and oils on a shelf, this is more of a exercise to see whats out there. I've been reading some interesting but contradicting information about VII's SSI's, temporary and permanent shearing, and real world shearing that doesn't follow what you would expect from higher vs. lower SSI VII's.
