My reservoir was low so i went and purchase subaru coolant to than find out that the previous time it was low my dad filled it with auto zone orange antifreeze. What should I do? Is it ok to fill the reservoir with the subaru coolant or do I continue to use the orange one ?

What ever you do don't mix them. I'm not sure on how the Orange stuff is on a Subaru system, but if you don't want to flush it you can add distilled water or more of the orange stuff. Just don't mix different color coolants. they can have unexpected chemical reactions to each other.
