STP® Global Extended Life Antifreeze/Coolant is recommended for use in all makes and models of foreign and domestic passenger vehicles and light duty trucks. It contains a proprietary formulation of premium corrosion inhibitors that provide extended protection against rust, corrosion and pitting caused by cavitation for all coolant system metals. It also provides excellent protection against temperature extremes, preventing freeze-up and boil over when used in accordance with OEM and product manufacturer’s guidelines regarding product dilution.
This product does not impart any colour change if mixed with another engine coolant. The superior performance and stability of premium extended life corrosion inhibitors allows them to go on working well beyond the lifetime of traditional products. When STP® Global Extended Life Antifreeze/Coolant is added to a coolant system after a complete drain, flush and fill, this product provides up to 250,000 km (150,000 miles) or 5 years of protection.
