I read in the owners manual that my WRX needs Subaru Anti-Freeze which is Ethylene Glycol (green).

 

It also states you must not mix it with other ethylene glycol anti-freeze???

 

So question is, with a second hand car you can tell your car has Subaru Anti-Freeze in it cos its green looking fluid, but surely then you can just mix any other green ethylene glycol anti-freeze into the radiator reservoir 50/50 for the desired protection? Or am I missing something? Is Subaru anti-freeze a specific type?

 

Comments and Feedback appreciated. :)

Not really but as a rule you shouldn't mix great quantities of different coolants, best off just flushing the system and making up a new batch.

Subaru stuff shouldn't be any different just costs more from om the dealer

Not sure what make I have but its blue [emoji2]
