I decided to preemptively replace plastic coolant pipes with updated (2017 and later) parts to minimize chance of catastrophic coolant leaks. Part of this procedure required supercharger removal. "While I am there" supercharger oil was removed and replaced with Scol Eaton Synthetic Supercharger Oil p/n 001-60550.
I sent virgin sample and one that came out of my supercharger (35,000km, some racing) to Blackstone for analysis. Their conclusion was that I could probably could go longer on change interval but "Insolubles are oxidized solids formed due to heat and
use, and they're high at 0.2%. They didn't cause any trouble we can see, and the oil change should've removed them."
Out of the bottle virgin oil:
Original fill supercharger oil at 35,000 kms with some racing (meaning, time spent at high rpms and high heat).
First question: Did you get the oil directly from Eaton, or is there another source (understanding you're in a different country than I).
Tangential question: Do you have the part numbers of the coolant pipes? I should consider this same operation, especially given the summer heat we get around here.

Ebay, and other online stores. Otherwise equivalents are readily available... ac delco... Audi etc. They also use eaton superchargers
Thanks for the valuable data point. Looks like some moderate interval length is appropriate (perhaps 30k miles maximum?) but definitely NOT a lifetime fluid with that 'oxidized solids' buildup.
