The fluid is the latest generation of the popular Petrygo coolant manufactured since 1989. It is a ready-to-use product with freezing protection level suitable for conditions prevalent in Poland (freezing point of <-35°C). It should be used undiluted for filling (refilling) cooling systems.
Petrygo Q has been developed based on ethylene glycol (1,2-Ethanediol) and deionized water. A complete package of enhancement additives, including organic corrosion inhibitors, stabilizers, anti-foaming agents, dye and denatonium benzoate, provides effective and long-lasting protection for engine components. Petrygo Q coolant does not contain hazardous substances, such as nitrites, phosphates, amines and borates.
This all-purpose product is suitable for all types of car engines, both new aluminium types and older engines. Petrygo Q coolant can be stored for 3 years from the production date. Its service life in a cooling system is minimum 3 years or 100,000 kilometres.
