Oil analysis sure can be a useful tool. When I first took my job and started an oil analysis program this unit had a severe intake leak that was found via analysis and repaired by an outside shop. The iron, chromium and nickel were all very elevated. Since the repair the metals have been trending down nicely.
This oil was drained and I refilled with Schaeffer's Supreme 7000 15W-40.
