Imo your best defense is give the oil PLENTY of time to reach operating temp. Bad things tend to happen when you hammer the throttle on cold/high viscosity oil (which is much higher stress on the pump)

On an oil analysis at 900+ miles there was metallic glitter in my oil. I drained that oil and put in a fresh change after 100 miles. I wonder if others have had this metallic glitter adding to the stress on these parts and creating the conditions for the stress fractures. I have no idea where this metallic glitter is from. I speculate it's the product of break-in.
