Flushing Oil Concentrate – Which size do I need?

Choose the most appropriate Flushing Oil Concentrate size for your particular need. Various size options are available –

Flushing Oil Concentrate is added directly to the oil immediately prior to the oil change. It is not recommended to be added to the oil and ran for extended periods of time. For the very best results, we recommend the following treatment rates –

Initial/Dirty Engine concentrated flush: add Flushing Oil Concentrate to the engine oil at 0.5 fl oz per quart of clean engine oil (12.5ml per liter of engine oil).

• 8 fl oz of Flushing Oil Concentrate treats a maximum of 16 quarts (4 gallons/19 liters) of oil
• 16 fl oz of Flushing Oil Concentrate treats a maximum of 32 quarts (8 gallons/38 liters) of oil
• 32 fl oz of Flushing Oil Concentrate treats a maximum of 64 quarts (16 gallons/76 liters) of oil
• 64 fl oz of Flushing Oil Concentrate treats a maximum of 128 quarts (32 gallons/151 liters) of oil
• 1 Gallon of Flushing Oil Concentrate treats a maximum of 256 quarts (64 gallons/302 liters) of oil

Continuing maintenance oil change flush (i.e. subsequent maintenance oil changes after the initial concentrated flush): add Flushing Oil Concentrate to the engine oil at 1/10th fl oz per quart of engine oil (2.5 mL per liter of engine oil).

(32 fl oz = 946 mL, 1 liter = 33.8 fl oz)
