(I know buster is going to freak out over this question, but here goes anyway
):
Just how incompatible would you imagine the base stocks, and AW,AF/detergent packs to be between the RLI 0W-30 and Sustina 0W-20 for a winter OCI blend??
Is there ANYTHING to worry about with this mix (regardless of buster's, or others' dissing of it)?
Looks like you've got Buster's response anyway.
The RLI 0W-30 base stocks are a blend of up to 30% vegetable oil and presumably (hopefully) PAO synthetics. The only thing that I can see unique about their additive package is that they use antimony in addition to modest levels of ZDDP as an AW agent.
They claim that their oils are fully compatible with other conventional and synthetic MOs.
I don't see any problem any problem blending with Sustina 0W-20.
I do have an alternative RLI suggestion, and that would be to use their 10W-60 which has a 187 VI instead.
To produce a 0W-30 with a 3.2cP HTHSV would require 60% of RLI 0W-30 resulting in a 207 VI. If you use RLI 10W-60 instead requires only have as much (30%) to produce the same HTHSV of 3.2cP but the VI will be 216.
It's hard to say if the oil would qualify as a 0W-30 although I would think so with such a high VI. Besides in you're climate VI is more relevant than a purely academic spec' of whether an oil will pump at -40 or -35C.
P.S. I'm certainly interested in how the Millers ND works out.
Do you plan on having a UOA done at the end of the season?
I'm sold on the nano technology, I just wish it came as an additive that we could add to any oil we want.
