I buy the Murrays concentrated (green) coolant from O'Reilly's Auto. It's only $9 and makes two gallons of 50/50 mix as opposed to $9+ for the 1gal premixed stuff and the $11+ 1gal. Prestone extended premixed?

Not really "adamant" or adams ant bout any coolant producer. I use Oreally too for bout everything. Oreily house brand is prestone.
End users have mixed coolants choices in the past. Big no no is using low cost yellow "old school" engine coolant with ext life or long life.

I am just wondering what the coolant formula makeup. of Toyota Long Life coolant (red/pink) (borate free) and true differentation might be.
Water quality varies . Coolant quality, formula makeup and proper application are important.
However the rest like color dye agents and word marketing aka "long life" "ext life" are just that marketing and branding.
