F-83 Plus

140204 pail, drum Deposit formation, Fuel consumption, High-temperature corrosion    
  • Reduces sodium, vanadium and sulfur deposits in the combustion chamber and exhaust spaces (valves, turbochargers).
  • Reduces high-temperature corrosion.
  • Minimizes low temperature acid corrosion due to sulfur.
  • Reduces fuel consumption.
  • Reduces carbon deposits.
  • Decreases smoking and particulate emissions.
  • Improves combustion efficiency.
  • Prolongs combustion gas-affected parts service life.
  • Keeps nozzles clean.

FUELTREAT F-83 PLUS is a specially formulated blend of combustion catalysts, ash deposit modifiers and corrosion inhibitors that improve combustion efficiency while at the same time, keep emissions low and prevent ash deposit formation in exhaust gas affected engine or boiler parts. The product is designed to control corrosive deposits of sodium, vanadium, and sulfur on valve seats and turbocharger blades. It prevents vanadium converting, sulfur dioxide to sulfur trioxide catalytically thus helps reduce the acid formation resulting from sulfur trioxide and exhaust steam. The former is a by-product of combustion, originating from the reaction of vanadium and sulfur. FUELTREAT F-83 PLUS will modify fuel ash in small solid non-abrasive particles, thus reducing ware on valve seats and exhaust gas affected machinery parts. The product is not affected by fuel centrifugal separation.


FUELTREAT F-83 PLUS is suitable for both medium and slow speed diesel engines facing problems related to combustion and to deposits resulting from vanadium, sulfur and sodium contaminants in the fuel.

Use and dosing

There are several methods to introduce the product to the fuel. The recommended, however, is to apply FUELTREAT F-83 PLUSĀ using a dosing pump into the fuel line prior to the suction side of the low-pressure feed pump. Alternatively, the product could be introduced into the suction side of the transfer pump when transferring into the settling or service tanks (after separation) or even into the bunker tanks prior to bunkering. Although these alternatives methods are acceptable, the product’s efficiency is reduced since mixing with fuel is not optimum. When using dosing pumps, particular care should be taken to ensure that the feeding pump pressure will be at least equal to the man metric pressure on the point of injection, otherwise, the fuel will flow back into the feeding circuit. Approved equipment should always be used. Dosage may vary from 1:6000 to 1:4000, depending on the engine or boiler condition and the quantity of emissions. The initial dose should be 1:2000 and should be maintained for three to four (3-4) weeks. Where the product is not introduced by using a dosing pump, a dose should be increased by 30-50% to account for insufficient mixing and product loss. Observe results and adjust accordingly.
