AMSOIL Propylene Glycol Antifreeze & Coolant (ANT) is formulated to provide benefits beyond those provided by today’s conventional antifreeze and coolant products. Unlike conventional ethylene glycol-based products, which are acutely toxic, AMSOIL Propylene is biodegradable and its low toxicity limits the threat to children and animals. Its unique formulation provides maximum cooling system protection in extreme temperatures and operating conditions.
Low Toxicity, Biodegradable
Conventional ethylene glycol-based coolants are toxic, presenting a poisoning risk if ingested by children, pets, livestock or wildlife. AMSOIL Propylene Glycol Antifreeze & Coolant is biodegradable, and its low toxicity limits poisoning risk.
Helps Prevent Metallic Corrosion and Erosion
AMSOIL Propylene Glycol is formulated with unique organic acids that form a protective layer that prevents corrosion on metal components. Independent tests reveal it greatly surpasses standards for metallic corrosion and erosion, achieving nearly perfect scores in ASTM corrosion and erosion testing on cast aluminum cylinder heads, steel, copper, solder, brass and cast iron and aluminum water pumps.
AMSOIL Propylene Glycol is a proprietary hybrid organic acid (HOAT) formulation that does not contain phosphate, nitrite, silicate, borate or amine found in conventional antifreeze/coolants. These materials are responsible for almost all scaling issues in cooling systems, commonly reacting with calcium and magnesium in water to form precipitates that adhere to metal surfaces and create scale and corrosion. They can also precipitate to form scale if the antifreeze/coolant inhibitor system is at the wrong pH or mixed with incompatible products. AMSOIL Propylene Glycol virtually eliminates scaling problems. It is much more resistant to issues caused when calcium/magnesium are inadvertently introduced to the radiator through tap water.
Low Toxicity Antifreeze and Engine Coolant
• Biodegradable, low-toxicity formulation limits the threat to children and animals
• Concentrated – requires mixing with distilled or high-quality water
• Protection up to 150,000 miles (240,000 km) or 5 years, whichever comes first, in passenger cars and light trucks; up to 1,000,000 miles (1,600,000 km), 20,000 hours of operation or 8 years, whichever comes first, in heavy-duty applications
• Greatly surpasses standards for metallic corrosion and erosion
• Phosphate-, nitrate-, nitrite-, silicate-, borate- and amine-free
• Compatible with all other antifreeze and coolant colors
AMSOIL Propylene Glycol effectively protects cylinder liners against cavitation erosion/corrosion pitting, without the problems associated with nitrite technology. Nitrites can cause aluminum corrosion, and they are being banned from coolants used by a growing number of manufacturers in both the heavy-duty and automotive markets. AMSOIL Propylene Glycol Antifreeze & Coolant is a top-performing technology that performs extremely well in ASTM D7583 (John Deere Cavitation Test) testing.
AMSOIL Propylene Glycol eliminates the need for supplemental coolant additives (SCAs), extenders and recharging cooling systems. It provides extended service life in all gasoline and diesel vehicles, with recommended intervals of 150,000 miles or five years, whichever comes first, in passenger cars and light trucks and 1,000,000 mlies, 20,000 hours of operation or eight years, whichever comes first, in heavy-duty and of-road applications.
Compatible With Other Fluids
AMSOIL Propylene Glycol is dyed neutral yellow and is compatible with all ethylene and propylene antifreeze and coolant colors, as well as all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems. It is also compatible with fully formulated diesel antifreezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations. Mixing propylene and ethylene glycol formulations can make it difficult to predict freeze protection. If mixing for top-off is unavoidable, it is recommended to flush the cooling system at the next convenient opportunity.
