STP® Extended Life Antifreeze/Coolant

STP® Extended Life Antifreeze/Coolant is a long service life product based on a proprietary organic acid technology (OAT). This ethylene glycol based product is free of silicates, phosphates, borates, nitrates, nitrites and amines. It protects coolant system metals against rust and corrosion and provides excellent high temperature aluminum protection. It is fully compatible with other similarly formulated OAT coolants and is recommended for use in newer model foreign and domestic cars and light duty trucks. When properly diluted and added as an initial fill, this coolant provides up to 250,000 km or 5 years service life protection in automotive applications.

For best results, Extended Life Antifreeze/Coolant must not be mixed with conventional high pH, phosphate, borate or silicate containing coolants. STP® Extended Life Antifreeze/Coolant has a distinctly orange colour to help differentiate it from conventional engine coolant, which is typically, but not always, green. While deleterious effects are not expected to be significant, the mixing of conventional coolants with STP® Extended Life Antifreeze/Coolant will result in a lower than expected lifetime (change-over intervals).

STP® Extended Life Antifreeze/Coolant offers the following advantages:

  • Extended service
  • Silicate, borate, phosphate, nitrite and amine free
  • Protects coolant system metals such as brass, copper, solder, steel, cast iron and aluminum
  • Compatible with other OEM and aftermarket similarly formulated organic acid technology (OAT) coolants

 

 

 

STP® Extended Life Antifreeze/Coolant meets the performance requirements of the following specifications:

  • ASTM D3306
  • GM 6277
  • Japanese Standard JIS K2234
  • VW TL 774D
  • Ford WSS-M97B44-D

Never use 100% coolant in concentrated form. A 50% dilution (i.e. when mixed with an equal volume of high quality soft, de-ionized or distilled water) 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.
