Yea & there are many types of additives that make an oil EP and fall into the GL specs. 'Active' and 'non-active' additives? Active would be say sulphur, non-active would be barium. Sulphur would cause the situation you have discribed (as seen in the oxidation on Pete's Quaife), barium would not but would still be a GL/EP oil.....but barium is far more expensive.
