GB PREMIUM Si-OAT ANTIFREEZE is an ethylene glycol based engine coolant concentrate, incorporating Organic Acid Technology and silicate, free from nitrites, amines, phosphates and borates. Unlike traditional coolants which use inorganic inhibitors, GB PREMIUM Si-OAT ANTIFREEZE has excellent hard water stability and very low inhibitor depletion rates.
PERFORMANCE FEATURES
GB PREMIUM Si-OAT ANTIFREEZE, when used at the correct concentration, provides corrosion protection up to 250,000km for passenger vehicles or 1,000,000km for trucks and commercial vehicles. It is recommended that the coolant be changed when these mileages are reached, or after 5 years, whichever is sooner.
