I would recommend reaching out to Pinon and asking at least from a warranty standpoint. In the end if I am buying a nice pinion gearbox bike I am fine with a little extra money each year to flush it with new oil from them. Especially if I have a belt drive I am saving a ton there and that amount for gearbox oil is probably not that much compared to chains and lubing and replacing cassettes and stuff like that.
In the end people are always trying to cheap out on silly stuff and for a system that is not cheap and doesn't require a ton of maintenance often it doesn't really make sense to try stuff that may not work or may not be rated for the gearbox and end your warranty for no reason.
