Fuel Oil Treatment
Six treatments covering storage, transfer and combustion. Formulated and batch-tested in our own plants, dosed from one litre per 6,000 litres of bunker.
What are you treating?
Why it matters
Heavy fuel changes in the tank.
Residual fuel does not sit still. Left untreated, what you bunkered is not what reaches the injectors.
Sludge
Asphaltenes and paraffins drop out and settle on the tank bottom.
Water
Separates and re-emulsifies, carrying through to the separator.
Microbial growth
Takes hold in the water layer beneath the fuel.
Poor combustion
Blocked filters, fouled pre-heaters, smoke and ash on exhaust valves.
Sheran manufactures six fuel oil treatments at its own plants in Fujairah and Athens.
The range
Nine treatments in this range.

1 / 9
Sherfuel Multi Purpose
Combustion treatment for heavy and marine distillate fuel
Dose
1 L per 2,000 to 6,000 L of bunker
Sherfuel Sludge Dispersant
Disperses existing sludge and breaks water-in-oil emulsions
Dose
Into the bunker tank before bunkering, after a compatibility test
Sherfuel Catalyst
Combustion improver, ash modifier and smoke suppressant
Dose
1 L per 4,500 L, rising to 1 to 2 L per 2,000 L above CCAI 840
Sherfuel Lubricity Improver
Non-metallic, phosphorus-free improver for low-sulphur diesels
Dose
1 L per 6 tonnes average, 50 to 400 ppm by analysis
Sherfuel Bio Control
Broad spectrum biocide against bacteria, fungi, yeast, algae and SRBs
Dose
50 ml per tonne preventive, 250 to 350 ml per tonne heavily contaminated
Sherfuel Vanaguard
Reduces the harmful effects of vanadium oxides and sodium salts
Dose
Manually before or during bunkering, or via metering pump
Sherfuel Coldflow Improver
fuel gelling and filter plugging in cold weather
Dose
250–1,000 ppm (mild 250 | moderate 500 | severe 750 | extreme 1,000)
Soot Remover Liquid
soot, slag and carbon fouling boiler and exhaust surfaces
Dose
0.25 L per MT/day (boiler) | 0.5 L per MT/day (main engine)
Soot Remover Powder
Differentiator is the dosing method: dry, through a soot blowing injector, distributed toward the rear of the flame path
Dose
0.5 kg per MT/day (boiler) | 0.125 kg per MT/day (main engines)

Common questions
Dosage, compatibility and supply.
It depends on the product and the fuel. FOT Multi Purpose doses at 1 litre per 2,000 to 6,000 litres of bunker. FOT Catalyst starts at 1 litre per 4,500 litres, rising to 1 to 2 litres per 2,000 litres where CCAI exceeds 840. FOT Bio Control runs from 50 ml per tonne preventively to 350 ml per tonne on heavily contaminated systems. Each product data sheet carries the full dosing guidance.
Yes. The FOT range is compatible with low-sulphur fuels, VLSFO and biofuel blends — dosing is adjusted to the specific fuel and treatment, so confirm your blend with us before the first dose.
A compatibility test is recommended whenever you are switching fuel suppliers or blending fuels from different sources, to rule out any interaction before treating a full tank.
CCAI (Calculated Carbon Aromaticity Index) estimates how well a fuel will ignite. A high CCAI signals poor ignition quality and combustion problems, which is one of the triggers for stepping up to FOT Catalyst.
FOT Multi Purpose ships in 25 L and 208 L drums, matching most vessels’ storage and dosing setups. Other pack sizes are available on request.
Dose continuously at the bunker tank as fuel is loaded, or as a batch treatment before transfer. Full dosing guidance is on the product data sheet for your specific vessel and fuel type.
