Two weeks since I've hit the "go button" on the filtered twin.  I can report that the oil, which I checked again yesterday, is absolutely clean.  Not black, not grey, not "just a tinge" of anything but yellow.  I run that engine every day, for 5-8 hours. 

I'll report back in about a month.

I 'm sure you have a way to make sure it's really circulating and getting filtered ???

I thought that even toilet paper roll filters couldn't remove suspended carbon in diesel engine oil, certainly not to clear oil levels.

That's why Mike is asking...  me too.

With my filter system the oil goes black fairly quickly.
It's probably very clean for much longer, but it is black.

Diesel oils are usually a detergent oil which means they are designed to clean the inside of the engine and pick up the carbon deposits and is why your oil goes black. To me this is exactly what it is meant to do. I had reservations about the toilet roll filter as I knew some truck drivers back in the 1970's that went over to them for cost saving but cost all of them engine rebuilds. They simply do not do the job as good as a proper paper element / cartridge type because of the type of paper used.
However one of these filters used on an engine that has not  usually have a filter of any kind is better than nothing so long as the full flow is there.

Is there any further change in the colour of the oil yet?

The oil is opaque.

My thoughts are about oil is firstly it is there to lubricate and secondly to pick up the contaminents and take thm to the filter to trap the larger particles but the smaller ones stay suspended in the oil until it is changed hence the oil changes colour to black. I can't see how a toilet roll catches those finer particles that a specific built paper element cannot trap.
I would not trust that system to do the job as well as a purpose built one. But this is my thoughts only and not my engine.
