Dione G-12+ Ready to Use is an ethylene glycol based engine coolant ready to use which uses Organic Acid Inhibitor Technology and is free from nitrites, amines, phosphates, borates and silicates. Fleet trials have shown that when used at the correct concentration coolants based on Organic Acid Inhibitor Technology continue to provide effective corrosion protection for up to 250.000 km for passenger cars and 500.000 km in commercial vehicles.
It is recommended that the coolant is replaced when the above mileages have been reached or after 5 years whichever is the sooner.
