You say you don't want an OAT coolant but if you don't use OAT chemistry then you are going to have some type of DCA/SCA. There isn't anything else to protect you against cavitation damage.
You're correct, but I'd rather have the same coolant for 6-7 years and add the DCA's as necessary, than to have to change the coolant every two years as well as adding the DCA's.
