"Kororin-kun allows users to select and simulate flow of different viscosity engine oils against each other at a range of ambient temperatures.
You can be experience the difference between Fresh Oil and Used oil through Kororin-kun ② like:
- Does Oil change after several mile use?
- How oil change via temperature difference?
- How is the used oil difference between different grades?
- Does oil link to ecology?

This tool is for demonstration purposes only and is not to be used for purpose of diagnosing or for identifying solutions for specific applications of an oil. It must be recognised that other factors, not taken into account here, such as friction and shear, can affect the rate of flow. This tool simply provides a visual portrayal of flow for educational purposes and cannot be used as a replacement for evaluating the flow characteristics of a specific oil."
