Pentofrost E coolant 1.5 liter bottle. Also known as Pentofrost ++ This is the exact antifreeze specified for all VW Common Rail TDI engines. This is purple coolant designed to last as long as your car. The primary difference between this coolant and the earlier pink VW/Audi G12 and G12+ coolants is the partial substitution of glycerine for some of the ethylene glycol content for reduced toxicity and environmental impact.

  Total system capacity is about 6 liters. Use a 50/50 mix of this coolant and water. This coolant is backwards compatible and can be mixed with earlier VW/Audi pink G12 and G12+ coolants.

  Fun fact - Valvoline is the blender and supplier for all coolant sold at Volkswagen Auto Group dealerships in North America. Zerex and Peak are Valvoline brands.
