RMI-25 – How much do I need?

Unlike other cooling systems treatments, it is impossible to put too much RMI-25 Cooling System Treatment in your radiator. Theoretically, you could run 100% RMI-25 in your radiator and the only difference would be quicker results. In practice though, most cooling systems usually require an antifreeze component sufficient to effectively reduce the freezing point of the coolant in cold climate areas.

Add RMI-25 Cooling System Treatment directly to the engine’s cooling system’s radiator.

It is recommended to add 8 fl oz of RMI-25 for a cooling system with a capacity up to 5 gallons/19 Liters.

For cooling systems above 5 gallons, it is recommended to use a minimum treatment of 2 fl oz per gallon of coolant capacity. When used with distilled water only, and no antifreeze, it is recommended to double this treatment rate, i.e. 4 fl oz per gallon.

Select the most appropriate size RMI-25 for your particular need. Identify your engine’s coolant capacity and choose from the various size options available –

  • 8 fl oz – can treat up to 5 gallons (19 litres). This is usually enough to treat regular cars, small pickup trucks, small agricultural tractors & machinery, commercial generators, etc.
  • 16 fl oz – can treat up to 8 gallons (30 liters). This is usually enough to treat medium to some larger pickup trucks, and similar sized agricultural and other off-road machines.
  • 32 fl oz – can treat up to 16 gallons (60 liters). This is usually enough to treat medium to large trucks, RVs, medium agricultural tractors & machinery, excavators, dozers, large ‘inboard’ motorboats, etc.
  • 64 fl oz – can treat up to 32 gallons (120 liters). This is usually enough to treat larger trucks, agricultural tractors, and other similar large machinery etc, large commercial generators, or a combination of several different engines.
  • 1 gallon – can treat up to 64 gallons (240 liters). This is usually enough to treat several large trucks & machinery, combinations of various vehicles, earthmovers, motorboats, truck or machinery fleets, etc.

Test cooling system pH level every 15,000 miles (24,000 Km) or 300 hours, and if necessary, re-treat the cooling system with RMI-25. Correct pH is 8.2 – 10. Simply use pH Test Strips to test.

Engines requiring antifreeze in the cooling system should have the ‘freeze point’ of the cooling system fluid checked during regular maintenance schedules.
