Product information

This product supersedes product no: 9-303.11, 9-303.11U

Unitor DieselPower Enhancer is used to improve lubricity, as well as help maintain colour and stability to control the formation of organic sludge and to inhibit corrosion.

Unitor DieselPower Enhancer also disperses accumulated deposits, and reduces filter clogging, injector sticking, and corrosion of bunkers and fuel lines.


  • Improves fuel lubricity
  • Reduces wear of fuel pumps and fuel injection equipment
  • Proven by independent tests -- HFRR and Bosch
  • Maintains long term storage and thermal stability of marine distillate fuels
  • Protects against corrosion
  • Protects against fuel injection fouling and fuel filter plugging




Directions for use

DieselPower Enhancer may be applied directly to bunkers or storage tanks but for best mixing should be applied to feed lines during filling.

DieselPower Enhancer has been tested for compatibility with materials of construction and may be used with copper, aluminium, brass, mild steel, 304 and 316 stainless steel, PFTE, Buna-N, polypropylene and polyurethane. DieselPower Enhancer should not be used with rubber, neoprene, PVC Hypalon, Viton, or ethylene/propylene rubbers.

Used as a lubricity improver and stabiliser

To get the full benefit of the lubricity protection a dosage of 1 liter of DieselPower Enhancer should be added to 4 tonnes of fuel.

Used to stabilise and maintain distillate colour

To stabilise and maintain distillate colour, the dosage level will normally lie in the range of 5 to 35 mg/l and dosage may vary depending on the fuel used. The correct dosage can be determined by laboratory test.

Used to inhibit sludge formation, disperse existing sludge and control filter plugging

To inhibit sludging formation, disperse existing sludge and control filter plugging the dosage level will normally lie in the region 40 to 80 mg/l.

If organic contamination is heavy, treatment at a rate of 1 to 2 litres per 5,000 litres fuel oil is recommended to all systems. Treat next bunkers at a reduced dosage of 1 to 2 litres per 10,000litres of fuel oil. Thereafter, assuming tests show satisfactory conditions, maintenance dosage of the order of 0.4 to 0.8 litres per 10,000 litres of fuel oil should be applied.

Note: If the tank being filled already contains some fuel, ensure that this fuel is also dosed at the same ratio.

Note: If microorganism contamination is suspected test the fuel using Unitor Bacteria Test Kit and if contamination is found DieselPower MAR 71 can be used to sanitise the fuel.
