I also have run these back to back on used oil and noted similar results. Also Noted slightly higher wear metals and more viscosity degradation (which could be a good thing depending on what you want) for the Edge Pro than the TWS over a similar ~7200 mile interval. Inconclusive until I test the TWS that is currently in the car as the wear metals could just be the engine aging.
