ShellZone 50/50


Shellzone Antifreeze is a superior quality, single phase, ethylene glycol based antifreeze. It is a low silicate, all-purpose coolant designed for use in both automotive and heavy duty diesel engines (with the use of SCA’s). Shellzone Antifreeze Prediluted 50/50 is a 50/50 volume mixture of Shellzone Antifreeze with deionized water.

Shellzone Antifreeze is specially formulated to meet the stringent aluminum corrosion protection requirements of today’s automotive engines. Because of its low concentration of silicate, it also complies with Cummins and other heavy-duty diesel engine manufacturer’s silicate requirements. This product is also suitable for use in industrial internal combustion engines where an antifreeze/coolant is required to provide protection against freezing, boil over, and corrosion.
