This car is known for disappearing coolant especially when the car is new. Factory fill is typically halfway between max and min at cold. My guess is the coolant level was low after a bit of driving, you brought your car in for service, they saw the coolant was low, and topped it off with the pink toyota coolant literally every other Toyota uses. The subaru coolant is already very dark to begin with, the pink must mixed made it near black.



As well, every FRS/BRZ/86 is made in the same factory in Japan. I'm very confident this is what happened and even for a hot country like the Philippines, it still uses the same "blue" coolant as the ones sold in North America, but you can always read the manual to make sure.


EDIT: I just read the Australian 86 owners manual and it also calls for Toyota Blue. Yes, the person at the dealership MESSED UP by telling you it needed pink coolant.
