Ethylene glycol is newtonian or non newtonian fluid?

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.

The most reliable way would be to conduct viscosity measurements in the lab. Since it is non-Newtonian, you would need to use a viscometer and then curve-fit the data to the non-Newtonian model most apt for paraffin wax. The same goes for thermal expansion coefficient as well.
