Sounds like a bunch of techno-babble to me. Seems to contradict itself, but not committing to a specific outcome. When oil is used mostly for lubrication, I can see that it would become contaminated with residue from the friction of the moving parts. In an engine, there is always some blow by that contaminates the oil. BUT....at the same time, back in the '70s, I recall a number of "old timers" insisted that re-refined oil was the best thing to use because it had already had the paraffin burned out of it. There was no talk of oil breakdown. I would think that oil used in a hydraulic system would last a long time, and would eventually become contaminated with material from the pump or cylinders it operates. I would think that things like residue from combustion, wear from moving parts, and heat would be the determining factors in deciding when oil should be changed. Keep in mind that not everything you read on the 'net is factual or truth. The oil producers have a vested interest in selling you more oil. The equipment makers have a vested interest in making your equipment last longer (but not TOO long ). These days, it seems that everybody has an agenda.
