Here's up an up close look at the PAG 100 refrigerant oil and water test :
These photos provide a closer look at the test using the PAG 100 oil and water (dyed blue). As soon as the oil is poured into the water (right) it starts to mix. The PAG immediately absorbs the water.

Although we didn't use exact measurements, our mixture of water to oil was about 50/50. The test was conducted at room temperature.

PAG 100 Refrigerant oil mixed with water (dyed blue)
The photo below easily demonstrates how the PAG 100 mixed with the water (dyed blue). This was accomplished after a slow pour of the oil, before any shaking or mixing.

PAG 100 Refrigerant oil mixed with water (dyed blue)
Here's a real close up look at the mixture of PAG 100 and water after being shaken vigorously for about 30 seconds. (Vigorous shaking is similar to the oil movement inside your A/C system when the compressor engages) We photographed this sample in front of a light in order to best demonstrate how the oil absorbed the water. It's easy to see that the PAG 100 refrigerant oil and water have completely mixed. What's also interesting to note is that the mixture did not separate...even after left standing for over 48 hours!
