I have searched all over the place and can't seem to find what I am looking for.

I want to know why would you change the thermostat to a low temperature one if the original does it's job correctly? At what point in the weather would the low temp actually be beneficial, I am in Tennessee so not the hottest place around but it has it's days. Is there any way to tell what thermostat is already there? Maybe during the initial heat cycle?
I am asking all of this because I do not know what I have. I don't want to go back to an OEM if the previous owner has a low temp, obviously because it is running good. But if it's OEM it is running good and I wouldn't need the low temp, I suppose.

I am sure this has all been discussed and I am just lost in the amount of thermostat post's out there.

On a side note where have you gotten your unicorn blood coolant at?
