STP® Global Extended Life Antifreeze/Coolant
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 or 5 years of protection.
STP® Global Extended Life Antifreeze/Coolant offers the following advantages:
- Recommended for use in all makes and models of foreign and domestic passenger vehicles and light duty trucks
- Add as top-up to any colour antifreeze
- Protects coolant system metals such as brass, copper, solder, steel, cast iron and aluminum
STP® Global Extended Life Antifreeze/Coolant meets the performance requirements of the following specifications:
- ASTM D-3306
- JIS K-2234
Coolant concentrate must be diluted with water prior to use. STP® Global Extended Life Antifreeze/Coolant should not be used in concentrated form. A 50% dilution is generally recommended for the best balance of protection against freezing, corrosion and summer boil-over. For increased freeze protection in extremely cold areas, a 60% volume concentration can be used. Concentrations of greater than 70% by volume are not recommended. High quality soft, de-ionized or distilled water should always be used to dilute coolant concentrate.
