Coolant additive packages are normally applicable for extreme and/or heavy duty applications.

Any gains are marginal with the current long life coolants actually employed.

For mixed metal coolant environments, stick with a glycol based coolant. Organic acid based coolants are more prone to cause nominal corrosion in the presence of a current.
