Countries with cold climate If greater anti-freeze protection is required in very cold climates, the proportion of the anti-freeze additive G12+ can be increased. A concentration of 60% offers protection down to about -40 °C. The concentration of the antifreeze additive must not be more than 60% , otherwise this would reduce the antifreeze protection.
