OEM Toyota Blue Super Long Life Coolant == Super Coolant Pre Mixed?
 

I bought a super coolant premix from the subaru dealership. I can't find anywhere that confirms nor denies that its the same thing from the blue toyota super long life. Since the engine is the same from fr-s and brz.. It should be ok to use the coolant I bought from subaru to top off my coolant?? It's near the low line while the engine is warm so I wanted to top it off.





Here's the one I bought from subaru dealership https://parts.subaru.com/p/subaru__B...A868V9270.html

If you bought the right pre mixed coolant for these cars from a dealer, don't worry your golden. You never know if you mix and match if it will handle longevity or proper specs right. So the Toyota stuff is fine or the Subaru stuff, prob best not to mix. I'm sure your fine if you only added a bit.


I base this on nothing more than ignorant common sense so grain of salt and all that.

I also have zero evidence to back anything up but given that it wouldn't make sense for Toyota to give you the wrong coolant (other than the person working their to just botch the transaction) it should be fine.
I personally went with the Subaru coolant because it's a Subie engine and why not.
