Small amount of top off coolant not meeting ES specifications will lower the overall SCA level to some degree based on the volume of top off between visits to your service shop. It is best to provide ES Coolant (or at least regular maintenance coolant like Compleat Premix) for top off purposes rather than let drivers or operators refill the system with incorrect coolant. If testing reveals that the SCA is significantly lower than 2.5 units per gallon, ES Liquid (CC2840) can be added to restore the level of protection to 2.5 units.
