You can expect only the best protection for your engine and drinking water systems with Starbrite Antifreeze -200°F (-129°C), even in the extreme cold weather. You’ll also be protected against corrosion with its premium additive package preventing corrosive damage from key alloys like aluminum, copper, brass, and solder, and still won’t damage rubber, seals, or hose materials. The 3X-died blue color provides excellent blow-through visibility and is formulated with virgin, non-toxic USP-grade ingredients. Starbrite Antifreeze is alcohol-free and ready-to-use or be diluted - simply follow the directions on the label.

With Starbrite antifreeze you’ll get burst protection to -200°F (-129°C) and freeze protection within a range of -98°F to -103°F (-72°C to -75°C). Most PG refractometers and/or hydrometers will not provide freeze point readings below -70°F.
