I found better UOA's with M1, 10W-30 in 2 of my Ford trucks (vs 5W-20/30) . However, I've stopped performing UOA's due to my personal belief that overall wear rates are not reflected in the PPM numbers. As plenty of engines need internal work even with good UOA results. BMW bearing failures come to mind, as do Ford's timing chain issues, and GM's balancer chain issues.
Instead, I prefer to choose adequate viscosity for the climate, choose a quality synthetic and change it at the severe service schedule or 5000 miles, whichever comes first.
The only faith I put in UOA results is trend monitoring. A sudden increase in a specific metal, vs the engine's history, may indicate a component failure.
