Provides protection for aluminium engine parts.
Supports efficient heat transfer.
Helps maintain cooling system reliability.
Designed for extended coolant service intervals.
Supports protection of compatible mixed-metal cooling systems.
The advanced formulation makes Valvoline HT-12 suitable for vehicles that specifically require this coolant technology.
Long-Life Protection – Up to 5 Years or 250,000 km
Valvoline HT-12 Antifreeze Coolant is engineered to provide extended service life under suitable operating conditions.
Its corrosion inhibitor package helps maintain cooling system protection throughout the recommended replacement interval.
Potential service life:
Up to 5 years.
Up to 250,000 km.
Actual replacement intervals depend on vehicle manufacturer instructions, operating conditions and cooling system maintenance.
Always follow the coolant replacement schedule specified in the vehicle owner's manual.
BMW, MINI & Rolls-Royce Cooling System Applications
Valvoline HT-12 Green is intended for compatible vehicles requiring the relevant coolant specifications used in selected BMW, MINI and Rolls-Royce applications.
The product information lists the following BMW coolant specifications:
BMW LC-18
BMW LC-87
Coolant compatibility must be confirmed using the vehicle manufacturer's requirements.
Important: Not every BMW, MINI or Rolls-Royce vehicle uses HT-12 coolant. Check the required specification before purchasing or replacing coolant.
Excellent Corrosion Protection
A vehicle's cooling system contains components made from different metals and materials that must remain protected throughout operation.
Valvoline HT-12 Si-OAT Antifreeze is formulated to help reduce corrosion and protect essential cooling system components.
Helps protect:
Aluminium engine components.
Radiators.
Water pumps.
Cooling passages.
Compatible metal components within the cooling system.
The corrosion inhibitor technology helps maintain the condition and reliability of the cooling system over time.
Ready-to-Use – No Dilution Required
Valvoline HT-12 Green 908833 is supplied as a ready-to-use antifreeze coolant.
Unlike concentrated antifreeze, the RTU formulation is prepared for direct use in a compatible vehicle cooling system.
Advantages of ready-to-use coolant:
No additional water required.
No manual mixing.
Convenient for routine servicing.
Suitable for coolant replacement and topping up where the specification matches.
Consistent pre-mixed formulation.
Do not dilute unless specifically instructed by the manufacturer.
Free from Selected Traditional Inhibitors
The advanced Si-OAT formulation is described as free from:
Nitrites.
Phosphates.
Borates.
Amines.
This inhibitor technology is designed to provide effective corrosion protection while meeting the requirements of compatible modern cooling systems.
Applications
Valvoline HT-12 Green 5L is designed for compatible passenger vehicles requiring the relevant HT-12 or manufacturer-specified coolant technology.
Typical applications include:
Passenger car engine cooling systems.
Selected BMW vehicles.
Selected MINI vehicles.
Selected Rolls-Royce vehicles.
Compatible modern light-duty engines.
Older vehicles where the required coolant specification is confirmed.
Compatibility Note: Select antifreeze according to the manufacturer's coolant specification, not colour alone. Green coolant from another brand or technology may not be interchangeable.
How to Use
Check Compatibility – verify that the vehicle requires the appropriate HT-12 or listed coolant specification.
Allow the Engine to Cool – never open a hot or pressurised cooling system.
Inspect the Cooling System – check the coolant level and condition.
Add Coolant – use the ready-to-use product according to the vehicle manufacturer's procedure.
Maintain the Correct Level – fill to the recommended level without overfilling.
Check Operation – follow the manufacturer's instructions for bleeding and checking the cooling system where necessary.
Important: Do not mix incompatible coolant technologies. When changing coolant types, follow the vehicle manufacturer's flushing and replacement procedure.
