Yes, you certainly can. But on the other hand, we all know that UOA can, and often does, provide valuable early warning of an impending disaster. My point is that, while "silent failures" do happen, we should very clearly be seeing mountains of evidence of harm if 20 wt oils were truly inadequate lubricants.
