Independent tests reveal AMSOIL Antifreeze/Coolants greatly surpass 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.

Anti-Scale
AMSOIL antifreeze/coolants are proprietary formulations that do 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, and they can also precipitate to form scale if the antifreeze/coolant inhibitor system is at the wrong pH or mixed with incompatible products. AMSOIL antifreeze/coolants virtually eliminate scaling problems.

Cavitation/Pitting Protection
AMSOIL Heavy-Duty Antifreeze & Coolant 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 Heavy-Duty Antifreeze & Coolant features top-performing technology that performs extremely well in ASTM D7583 (John Deere Cavitation Test) testing.

Long-Life Formulations
AMSOIL antifreeze/coolants’ proprietary formulations provide durable and long-lasting protection of cooling system components. AMSOIL Passenger Car/Light Truck Antifreeze & Coolant can be used for 150,000 miles or five years, whichever comes first, in passenger cars and light trucks. AMSOIL Heavy-Duty Antifreeze & Coolant can be used for 1,000,000 miles, 20,000 hours of operation or eight years, whichever comes first, in heavy-duty and off-road applications.

Compatible With Other Fluids
AMSOIL antifreeze/coolants are compatible with all ethylene and propylene antifreeze and coolant colors, as well as all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems. Mixing propylene- and ethylene-glycol formulations, however, can make predicting freeze protection difficult. If mixing for top-off is unavoidable, we recommend flushing the cooling system at the next convenient opportunity.
