Hi ya @radroach .......

My FR-S owners manual says:

“You can use any similar high-quality ethylene glycol-based non-silicate, non-amine, non-nitrate and non-borate coolant with long life hybrid organic acid technology”

So, unless you're are a chemist and can “read” the MSDS and chemical ingredients sheets for the type of Prestone you put in there …….OR, you feel lucky, like the others, I’d suggest you drain out whatever possible precipitate(s) you may have created in your car’s cooling system, flush the system and fill it up with Subaru stuff.
