It does seem there would be a high level of 0.1 microns to 4 micron particles (soot, silica, etc.) getting past the air filter and rings into the oil that an Ultra would keep passing. Over time of course. We do need that comparison between Ultra vs. MicroGreen in a long term oil test, checking for those very small particles to see if they have built up.
Without that study, I'll accept parallel filtration as basically valid and just go with getting more of the tiny stuff out as the best way to go. Why not, since MicroGreen isn't much more expensive at all.
