				Coolant and yes I have searched and read
			 
			 
			
		
		
		
			Still I did not see any definite conclusions to the OEM Porsche OAT coolant. Is there a substitute OAT that equals the original (and upgraded) Porsche coolant ? 
 
I know Porsche does not manufacture coolant so what are you guys using ??
