DIESEL FUEL ANTI-WAXING ADDITIVE &
COMBUSTION REMOVER

PROTECT DIESEL FUELS AGAINST WAXING DOWN TO -22°C

Diesel fuel is a notoriously bad performer in cold weather, when below zero temperatures can lead to apparent 'freezing' of the fuel.

These problems are caused by waxes in the fuel, which precipitate out as very small crystals as the temperature drops below the cloud point of the fuel.

Continued low temperatures will cause these fine crystals to grow together into much larger crystals which can block fuel filters and pipelines, causing engines and heating plant to fail due to fuel starvation.

These low temperature problems can be overcome by treating diesel fuel and heating oil with WAXBREAKER GOLD diesel additive during the winter months. Users can determine the degree of protection required, down to below -22°C, when severe conditions are forecast.

There are also year-round benefits when treating fuel with WAXBREAKER GOLD. Extra components improve ignition characteristics and combustion, keeping fuel injectors cleaner for longer periods. The result is to reduce smoke & emissions, giving a cleaner exhaust, as well as improving smoothness & fuel efficiency, so that users benefit whatever the weather.

THE BACKGROUND TO FUEL WAXING PROBLEMS

The temperature at which a given fuel will give rise to problems (the operability limit) is indicated by the COLD FILTER PLUGGING POINT (CFPP) test. Generally, the lower the CFPP, the better the low temperature characteristics of a fuel. BS2869 requires Oil Companies to supply diesel fuel with a CFPP of at least -15°C from October to March (-12°C for gas oil / "red" diesel), but only 0° during the summer months. Often it is well into the winter before diesel operators can be sure that their fuel is 'protected' to -15°C, as a result of adding winter grade fuel into tanks still containing summer grade fuel.

Although diesel fuels are formulated to provide "acceptable performance under typical winter conditions", diesel fuel treated to the British Standard can be inadequate, particularly for mobile applications, which are subject to a "chill factor". Additionally, changed operating practices at refineries, to produce fuels with a lower cloud point, has resulted in lower cetane number fuels with worse weather starting performance, and fuels with lower viscosity and lubricity. Fuel injection systems rely on the fuel to provide lubrication and hence prevent fuel pump wear.

HOW WAXBREAKER GOLD WORKS

WAXBREAKER GOLD is a hydrocarbon based liquid which is added, in advance, to diesel fuels during the winter months at dosage rates as low as 1:1000. Higher dosage rates can extend protection below -22°C, should this be required.

WAXBREAKER does not prevent the formation of wax crystals, and the cloud point of fuel is not lowered. WAXBREAKER actually encourages the initial formation of wax crystals, which remain as long needle-like crystals which can pass through fuel filters. The viscosity of treated fuel does not increase substantially, unlike untreated fuel, another factor leading to fuel starvation at low temperature.

Dispersants in WAXBREAKER GOLD maintain the fine wax crystals in suspension throughout the fuel, preventing separation and settling, which can block outflow pipes and filters. Fuel treated with WAXBREAKER GOLD will continue to flow through fuel lines and filters down to temperatures below -22°C.

APPLICATION & USAGE:

WAXBREAKER GOLD is effective with diesel fuel and 35 second fuel oil (gas oil) and will give similar results with both. Addition must be made at temperatures above the cloud point of the fuel (as a general guide, above -2°C), BEFORE any wax formation occurs.

WAXBREAKER GOLD at normal dosage rates will not re-dissolve wax which has already separated out.

WAXBREAKER GOLD may be added either to vehicle fuel tanks or to bulk storage tanks. Ideally it should be added before filling/topping up the tank, to ensure rapid, complete mixing with the fuel. Alternatively, manual agitation of the fuel, recirculation or the use of a compressed air lance, may be used to ensure complete blending of the additive with the fuel.

IMPORTANT: Check all fuel tanks for the presence of water on a regular basis and drain any water off well before the onset of winter.
