As perfectly stated by others just slap a cheapie new oil filter on. This will not only catch the flushed crap better, no sense in flushing out a dirty filter that is easily changeable. Can't think of a good analogy - but essentially the oil filter is a disposible item, why clean it?

Check my web site for a super duper flush procedure designed for high milers.

To answer another caller's question, from my several years of experience the flush really helps in the oil consumption department. What?? (you say)

In higher mileage, dirty engines when changing over to synthetic oil, the oil consumption rate can temporarily go up. Sometimes quite surprisingly. What happens, is indeed the synthetic oil starts cleaning the petroleum oil gunk out - this junk, when cleaned, it goes into the oil and very often escapes the oil rings and is combusted along with some of the synthetic oil. The flush accelerates the cleaning and hence cuts back on this oil usage. I know it sounds weird...but I and many others have seen this happen. It's pretty interesting when the oil consumption period stops....it just stops. Period.
