Danny,

Very primitive system: filter cloth between 2 metal screens in the bottom of an upside down plastic quart oil bottle. I pour from one gallon cantainer to another with the filter in between.

In over 20,000 miles betweeen 2 300SDs, I have not plugged either an inline or a can filter. I only use a 5% or less mix, so there isn't any smoke visiable.

Using used crankcase oil for fuel makes waste oil worth whatever the price of Diesel fuel is. I figure the added oil also helps lubricate the injection pump what with the sulphur content of the Diesel getting lower all the time.
