Well, it has gone too far now. After over a week of continuous circulation, the cutting oil's color has changed from white to purple. I think the density has also increased. Pump makes a vibration due to load now.
Checkout the pics.
You said “The coolant turned to a thicker consistency than paint!" ...what about its color?

Metals involved are brass, Cu, FeS (or some alloy, for making 'T'). As for the pump, it uses Iron, Carbon, Magnets Cu terminals and small coils. I used solder to seal the block and T. Brazed the reservoir.

Synthetic oil for Al and yellow metals, is that it? Will it last at least a year? As replacing it every six months is not practical.
What if I increase the ratio even further? A few teaspoons of the cutting oil (which I have at my disposal now) with a liter of water.
And what if I introduce a filter?
