Water and mineral oil in the same loop.

Has anyone ever tried putting mineral oil in their water loop? Not a lot, just about 1/3 of the reservoir. To achieve something similar to those, oil and water with some food coloring in a bottle, projects we used to do in elementary.

buy distiled water (car battery bottled water)+ coffee paper, mineral water cause corrosion, a water cooler distill water is free from residue, you should add biocide to prevent algae in the loop, food dye causes stain and gunk on water block

Mineral oil just means petroleum oil, and is a term to distinguish it from synthetic oils or edible oils such as vegetable oil or animal fats. It is definitely not the same thing as mineral water.

The mineral oil has much less heat capacity than water so it will reduce the effectiveness of the cooling. Furthermore the pump will churn the mixture into an opaque milkshake. On the bright side the oil will help prevent any corrosion.

Not to mention that most watercooling loops use rubber o-rings which might degrade over time, depending on what specific oil type is used, although this would be one of my lesser concerns.

As it was mentioned, water has a higher specific heat than mineral oil which makes it a better carrier of thermal loads than mineral oil, so it mineral oil would actually detract from the cooling capability in the loop rather than being a water-based solution, or even pure distilled water.
