Traditional blue anti-freeze specially for all classic, vintage & veteran cars. Does not contain OAT inhibitors that can be damaging in older vehicles (5 litre, 25 litre)
Classic Oils 2-Year Blue Anti-Freeze is a traditional Ethylene Glycol based anti-freeze and engine coolant, specially formulated for Classic, Vintage and Veteran vehicles.

Classic Oils 2-Year Blue Anti-Freeze 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 anti-freeze 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 Anti-Freeze 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.
