MaxLifeTM/Multi-Vehicle Antifreeze/Coolant is the only antifreeze that contains AlugardTM Plus, a patented additive that makes it compatible with any other color antifreeze. This universal formulation helps extend the life of your vehicle by keeping your vehicle's engine temperature stable in all climates and driving conditions by transferring heat from the engine to the radiator. Other antifreeze brands claiming 'all makes, all models' use a corrosion inhibitor package without silicate. These chemistries, when mixed together, may fail to protect the cooling system from rust and corrosion.
