Gotham Long Life Supreme Diesel 50/50

This 50/50 premix Supreme Diesel antifreeze/coolant is a, hybrid organic acid technology (HOAT), extended life, low-silicate, non-phosphate product suitable for automotive/light duty and heavy duty diesel applications. Since this is a HOAT extended life antifreeze/coolant it combines organic acid salts with conventional inorganic salts and azoles; this makes it compatible with all types of both extended life and conventional technology antifreeze/coolants.

This antifreeze is precharged, meaning that it contains a minimum of 2400 ppm nitrites. Its additives effectively control wet sleeve cylinder liner pitting/corrosion in heavy duty diesel engines. The primary corrosion inhibition system consists of a combination of salts of carboxylic and phosphono-carboxylic acids. These inhibitors deplete very slowly relative to conventional inorganic salt compounds, providing the extended service life of this antifreeze. It utilizes a low-silicate level (less than 250 ppm as silicon) and is free of phosphates and amines.

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, steel, iron, copper, soldier 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.

In automobiles, light trucks, SUV’s, vans and other light duty applications, this product will provide a service life in excess of 5 years or 250,000 kilometers. In heavy-duty diesel applications (in which a formal monitoring and maintenance program is in place) it can provide a service life of 1,000,000 kilometers with the addition of our heavy-duty supplemental coolant additive at 500,000 kilometers.
