Gotham Extended Life 50/50

Our Extended life premix 50/50 antifreeze/coolant contains a proprietary hybrid organic acid technology (HOAT) inhibitor system that is significantly more durable that conventional additive systems for automotive, light duty and basic heavy-duty service, resulting in a 5-year, 250,000 kilometer service life. This extended life antifreeze/coolant contains no phosphates, silicates, nitrites or amines. However, it is a balanced combination of organic and inorganic additives, a true hybrid, and is compatible with both organic acid long life coolants and conventional inorganic salt coolants.

In addition, this antifreeze/coolant contains an advanced inhibitor system that provides a wide range of inhibitors which protect all cooling system metals including aluminum, iron, copper, steel, solder and brass.. Together with the glycol base, these inhibitors combined with other additives, give year-round protection against freeze-ups, boil-overs and engine cooling system corrosion. This antifreeze/coolant also includes ingredients to disperse minor oil leakage, prevent fouling, control hot surface scaling and it will not damage auto finishes or rubber parts.

This product is compatible with all Extended life coolants including GM 6277M etc.
