Unique Stop Leak Protection Proprietary Formulation to Prevent and Stop Radiator Leaks without Additional Radiator Stop Leak Products
Universal, Long-Life Antifreeze For Use in All Diesel and Gasoline Vehicles, Heavy-Duty and Automotive
Low-Toxicity – An Ideal Choice for RV, Snowmobile, ATV and Marine Applications
AMSOIL Biodegradable Propylene Glycol Long-Life Antifreeze Engine Coolant (Product Code: ANT) provides benefits far beyond those found in conventional antifreeze and engine coolant products. Industry tests show that propylene glycol’s (PG) anti-corrosive properties are far superior to traditional ethylene glycol (EG). AMSOIL Biodegradable Antifreeze Engine Coolant’s unique Stop Leak Protection proprietary formulation adheres to metal and self seals hairline cracks to help prevent and stop radiator leaks without additional radiator stop leak products.
AMSOIL Biodegradable Propylene Glycol Antifreeze Engine Coolant provides maximum protection against corrosion in a wide variety of vehicles and it meets the long-recognized need for a universal antifreeze coolant fluid. AMSOIL Biodegradable PG Antifreeze Engine Coolant is formulated for use in heavy-duty commercial diesel vehicles as well as in light-duty trucks, cars, motorcycles and recreational vehicles. It’s compatible with other fluids, with aluminum engine blocks, and with all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems.
Unlike conventional ethylene glycol antifreeze coolant products, which are acutely toxic, AMSOIL PG Antifreeze Engine Coolant is biodegradable and its low toxicity limits poisoning risk to children, pets, livestock or wildlife, making it an ideal antifreeze for RV, snowmobile, ATV and some marine applications.
AMSOIL Biodegradable Propylene Glycol Long-Life Antifreeze Engine Coolant’s unique formulation provides maximum antifreeze and cooling system protection in the most extreme temperatures and operating conditions. It’s long-life formulation offers a much longer service life than conventional products, eliminating the need for supplemental coolant additives (SCAs), extenders and recharging cooling systems. It provides extended service life in all gasoline and diesel vehicles.

Exceeds Corrosion Standards in Industry Tests
AMSOIL Biodegradable Propylene Glycol Long-Life Antifreeze Engine Coolant is formulated with unique organic acids that form a protective layer that prevents corrosion on metal components. Independent tests reveal AMSOIL PG Antifreeze Engine Coolant 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.
- Standard corrosion allowances for loss in aluminum and solder are less than 60 mg. AMSOIL Propylene Glycol lost 0 mg in aluminum and less than 6 mg in solder.
- Standards for iron, steel, copper and brass allow a maximum corrosion loss of less than 20 mg. AMSOIL Propylene Glycol never exceeded a 3 mg loss in any of those metals in a testing period that was run for 10 weeks, three weeks longer than required tests.
Free of Silicate, Phosphate, Nitrite, Nitrate, Borate and Amine Found in Conventional Antifreeze to Help Eliminate Radiator Scaling
AMSOIL Biodegradable Propylene Glycol Antifreeze Engine Coolant is a poly organic acid formulation (POAT) that does not contain inorganic acid salts (phosphate, nitrate, nitrite, silicate, borate, amine) found in conventional and hybrid organic acid (HOAT) 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 PG Antifreeze Engine Coolant virtually eliminates scaling problems. It is much more resistant to issues caused when calcium/magnesium are inadvertently introduced to the radiator through tap water.
Provides Protection to Cylinder Liners Without the Use of Nitrites
Heavy-duty coolants typically contained nitrite and nitrite/molybdate technology to protect against cavitation erosion and corrosion pitting. However, because of its advanced poly organic acid technology (POAT), AMSOIL Biodegradable PG Antifreeze Engine Coolant is able to effectively protect cylinder liners against cavitation and corrosion without the use of nitrites. 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 PG Antifreeze Engine Coolant is a top-performing technology that performs extremely well in ASTM D7583 (John Deere Cavitation Test) test.
Reduces Risk of Bearing Damage
AMSOIL Biodegradable Propylene Glycol Antifreeze Engine Coolant also gives an added measure of protection to engine bearings in the event of crankcase contamination with antifreeze and coolant:
According to Arco Chemical Company (Document OP88-791-7.5M “The Facts about Propylene Glycol Antifreeze”), “PG-based antifreeze has shown reduced risk of bearing damage if introduced into the oil by head gasket leakage or failure. A Detroit Diesel 8V92T engine was run on a dynamometer for one hour at full horsepower (432 HP) with 8 percent [propylene glycol antifreeze] poured directly into the crankcase…no excessive wear was shown on bearings run with the 8 percent PG coolant when the engine was torn down.” In contrast, “one-half to one percent of ethylene glycol in the oil causes rapid bearing failure, resulting in the shutdown of the engine.”
Helps Stop Radiator Leaks Without Additional Radiator Stop Leak Products
AMSOIL Biodegradable Propylene Glycol Antifreeze Engine Coolant adheres to metal. It’s unique Stop Leak Protection proprietary formulation self seals hairline cracks in welds and seams to stop and prevent radiator leaks without additional radiator stop leak products or fibrous materials.
AMSOIL Biodegradable PG Antifreeze Engine Coolant’s long-life formulation lasts longer than conventional products. It eliminates the need for supplemental coolant additives, extenders and recharging cooling systems. AMSOIL PG Long-Life Antifreeze Engine Coolant provides extended service life in all gasoline and diesel vehicles:
- Protection up to 6 years, 600,000 miles or 12,000 hours of operation, whichever comes first, in heavy-duty and off-road applications
- Protection up to 5 years or 150,000 miles,whichever comes first, in passenger cars, light-duty trucks, vans and RVs
- Does not require use of supplemental coolant additives (SCAs) or extenders.
AMSOIL Biodegradable PG Antifreeze Engine Coolant is dyed neutral yellow and is compatible with all ethylene and propylene antifreeze and coolant formulations on the market, including DEX-Cool, Sierra and Zerex. It is also compatible with fully formulated diesel antifreezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations. It is compatible with aluminum engine blocks and all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems.
Note: 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.
Conventional ethylene glycol-based coolants are toxic, presenting a poisoning risk if ingested by children, pets, livestock or wildlife. AMSOIL Propylene Glycol Antifreeze Engine Coolant is biodegradable, and its low toxicity limits poisoning risk.
AMSOIL Biodegradable PG Antifreeze Engine Coolant may be used in over-the-road diesel trucks as well as passenger cars, light-duty trucks, vans and RVs. Also for motorcycles, ATVs, snowmobiles and some marine applications.
