Farnsworth you are some kinda valuable asset to this community with the information you provide. Thank you for that explanation. We may have to sticky this yet for all the good stuff it has or make a new thread with all you have contributed.

So, what is your opinion on running motor oil vs th GM supercharger oil? I have a breather nut, so there should be no pressure build up in the reservoir if my breather nut is functioning correctly, right? So is there any of the bearings or rotor pack seals that are not compatible with motor oil? I cant imagine the viton seals would have any adverse reaction. But I have seen metal incompatibilities before, mostly in gear boxes though where yellow metals can be used.

Anyway, just interested in your thoughts on the matter.
