hobot, engines without filters normally it is recommended non detergent oil, to allow the particles to ''sludge'' up, detergent oil with filters to hold in suspension and hope fully taken out by filter.

I understand that concept, but wouldn't it also make sense to keep them in suspension and change it out often?

I've been using high-detergent Redline synthetic in an old Guzzi Eldorado (no oil filter) with the same results I saw in the Commando - at relatively constant oil-change intervals, the oil comes out cleaner looking over time. This program seems to be working for me.
