Parent Petroleum Co. Premix Antifreeze with SCA CPA-SCA

larger image Castrol Premix Antifreeze with SCA (Supplemental Coolant Additive) is a premix (50/50 pre-diluted with deionized water) version of Castrol Heavy Duty Antifreeze with SCA. Castrol Premix Antifreeze with SCA is a diesel specific coolant, formulated to provide superior engine protection for heavy-duty cooling systems. Since the Castrol Premix Antifreeze with SCA is pre-charged with SCA and premixed with deionized water, the addition of SCA's and water when topping off is not necessary, Castrol Premix Antifreeze with SCA is a low total dissolved solids, low silicate coolant that incorporates nitrite to provide superior wet sleeve liner cavitation corrosion protection. Additional advantages include its phosphate free formula and state of the art inhibitor package that reduces the risk of scale and inhibitor drop-out.
