AMSOIL 250,000 Mile Antifreeze

Minerals found in tap water combine with coolants and form scale called phosphate scale. This scale coats the interior of radiators, radiator hoses, and engine coolant passages causing reduced heat transfer and cooling efficiency. Eventually your vehicle can overheat and run hotter than it's supposed to. This can burn and thicken your motor oil causing excessive engine wear and premature engine wearout. Tip: Use distilled water when changing out your antifreeze and of course use AMSOIL Propylene Glycol 250,000 mile antifreeze for the ultimate protection.

Propylene Glycol Antifreeze and Engine Coolant
AMSOIL Antifreeze & Coolant is newly formulated to provide benefits far beyond  those found in today's conventional antifreeze and coolant products. This revolutionary formulation provides maximum antifreeze and cooling protection in the most extreme temperatures and operating conditions. And unlike conventional ethylene glycol based products, which are highly toxic and even fatal, AMSOIL Antifreeze & Coolant is formulated with propylene glycol. It is  biodegradable and requires no special disposal costs or procedures in most  areas. Above all, its low toxicity presents no threat to children, pets or wildlife

Now, AMSOIL Antifreeze & Coolant provides even greater benefits:

Lasts Longer
AMSOIL Antifreeze & Coolant contains a proprietary poly organic acid technology. It eliminates the need for periodic changing or recharging of  cooling systems. There is no need for supplemental coolant additives. AMSOIL Antifreeze & Coolant provides extended service life in all gasoline and diesel vehicles. It can be used for seven years or 250,000 miles in passenger cars, light-duty trucks, vans and recreational vehicles. It lasts seven years or  750,000 miles in over-the-road diesel trucks.

Compatible With Other  Fluids
AMSOIL Antifreeze & 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.

Stops Leaks
AMSOIL Antifreeze & Coolant adheres to metal. It self-seals hairline cracks in  welds and seams to prevent leaks, without additional stop-leak products or  fibrous materials.

Prevents Metallic Corrosion
Independent tests reveal AMSOIL Antifreeze & Coolant surpassed standards for metallic corrosion. It plates to metal to protect even when  exposed to acids and salt spray. Standard allowances for loss in aluminum and solder are less than 60 mg. AMSOIL Antifreeze & Coolant lost 0 mg in aluminum and less than 6 mg in solder.

Standard for iron, steel, copper and brass allow a maximum loss  of less than 20 mg. AMSOIL Antifreeze and Engine Coolant never exceeded 3 mg loss in any of those metals in a testing period that was run for 10 weeks, three  weeks longer than required tests.
