Patman Flush is for real and is useful in testing situation as Patman pointed out and useful if last OCI went bad to clean things out as someone else suggested.
Now if you could do the flush and save the oil, run it through a filter cart, then re-use if for another flush. Maybe get 10 flushes for a gallon jug of cheap oil.
