There are fine particles that you can't filter out, which don't do nice things to injection pumps and injectors at 2000psi. It's up to you, though. BTW, I think re-using the 9-hour Delo in your crankcase is fantastic!
What sort of "fine particles" can't one filter out? Are you talking about steel? The insides of the IJP and the injectors are steel, but most debris from motor oil is bearing/ring material, substantially softer than steel, isn't it? And at less than 1-2 microns, how much is going to cause a problem?
