Classic Oils 2-Year Blue AntiFreeze

Classic Oils 2-Year Blue AntiFreeze is a traditional Ethylene Glycol based antifreeze and engine coolant, specially formulated for Classic, Vintage and Veteran vehicles.

Classic Oils 2-Year Blue AntiFreeze uses Inorganic Acid Technology (IAT) suitable for historic vehicles.  IAT provides iron and steel corrosion prevention by nitrites and nitrates, aluminium protection by silicates and phosphates, lead solder protection provided by molybdates and includes borates to help control acidity.

Choosing the correct antifreeze for your historic vehicle is essential as many modern anti-freezes incorporate Organic Acid Technology (OAT) chemistry which has been found to be damaging in older vehicles.  OAT anti-freezes are typically red, pink or orange in colour.

2-Year Blue AntiFreeze can be used all-year-round in pumped or thermosyphon cooling systems.  It provides a high degree of corrosion protection for all engines, whether they are predominantly of aluminium or ferrous construction.  It does not evaporate in use and is not flammable.
